Conditions & References 6 : Example 6 [Composition of Polyester] By using the effect of the hafnium (IV) compound as an esterification catalyst, the synthesis of polyester shown in Table 3 was studied (S. R. Sandler and W. Karo, Polymer Synthesis, 2nd ed. (Academic Press: San Diego, 1992) Vol.1, Chapter 2). A Soxhlet tube filled with dried molecular sieves 4A (about 1.5 g) was connected to the top of a 5 ml eggplant flask contained with a teflon coated magnetic stirrer, and a cooling tube was further attached over said Soxhlet tube. 10 mmol of hydroxycarboxylic acid, 2 ml of o-xylene and 0.2 mol percent of hafnium chloride (IV).bul.(THF)2were added and heating reflux was conducted in the argon for 24 hours. After the reaction, a solution wherein the mixture solution was dissolved into 30 ml of chloroform was poured into 150 ml of acetone while being stirred. The white precipitation that was produced, was collected by filtration, and dried under reduced pressure. Furthermore, by the same method, 10 mmol of dicarboxylic acid, 10 mmol of diol, 2 ml of o-xylene and 0.2 mol percent of hafnium chloride (IV).bul.(THF)2 were added and heating reflux was conducted in the argon for 24 hours. After the reaction, the mixture solution was dissolved in 200 ml of chloroform, and 30 ml of methanol was added. The mixture solution was concentrated, the white precipitation thus produced was collected by filtration, and dried under reduced pressure. [0028] The results are shown in Table 3. In Table 3, the following are shown: the yield represents isolated yield; DP stands for the degree of polymerization; DP and the number average molecular weight (Mn) are values obtained by 1H NMR; the weight-average molecular weight (Mw) is the value wherein gel permeation column chromatography (two columns of Two linear TSKgel-GMXXL (Tosoh Corporation) connected in series were used) is conducted to 0.2percent by weight of the generated polymer in THF at 40° C., with polystyrene as a standard; the value in parenthesis for HO [CO(CH2)11O]nH is a value of thermal polymerization condensation in the absence of catalyst; the various values for polyester in the bottom line are the values obtained by using 1 mol percent of hafnium chloride (IV).bul.(THF)2 and conducting the reaction for 4 days. These results revealed that the hafnium chloride (IV).bul.(THF)2 is useful as a catalyst for polycondensation reaction in the method for preparing polyester using ω-hydroxycarboxylic acid or the method for preparing polyester using α,ω-aliphatic dicarboxylic acid and α, ω-aliphatic diol.

1 :Example 1; Oxidative Ozonolysis of Oleic Acid; A micro falling-film reactor was used for the first part of the reaction, the reaction of ozone and oleic acid. The system consisted of 64 channels with a channel width and a channel depth of 300 μm and a channel length of 75 mm. The channels were operated in parallel and were etched through for educt input and product removal. The cooling channels corresponded in their diameter to the reaction channels. By virtue of the construction of the microreactor, contact between gas and liquid took place solely in the cooled region. The reaction was carried out in countercurrent, although co-current operation is also possible. Technical oleic acid with the following composition was used for the ozonolysis: 5percent palmitoleic acid (C16:1-FA), 69percent oleic acid (C18:1-FA), 13percent linoleic acid (C18:2-FA), 1percent linolenic acid (C18:3-FA) and 1percent gadoleic acid (C20:1). The other constituents were generally fatty acids with a chain length of C12 to C20. To dilute the reactants, the technical oleic acid was mixed with pelargonic acid in a ratio of 1:2. Owing to their instability, the ozonization products were directly reacted and cleaved with oxygen in microreactors. In such a fixed-bed microreactor consisting of 50 parallel, 70 mm-long reaction channels, with a diameter of 600 μm, with 25 μm thick filters at the outlet of the microchannels, providing for retention of the catalyst powder, having particle diameters of 50 to 80 μm, using zeolite activated with manganese, as described in International Published Application WO 95/21809 A1, the reaction was carried out at 95° C., the reactor being heated with thermal oil. In view of the residence time required, two reactors of this type were arranged in tandem. The reactors for the second reaction step were operated in co-current (trickle flow) with oxygen, the mass ratio between ozonization products and oxygen being adjusted to 90:10. However, countercurrent operation is also possible. In all tests, ca. 0.3 Nl/h oxygen was used per reactor. The heat of reaction was dissipated through the thermal oil. Both reaction steps were carried out continuously. The first reaction step took place at 20° C. 0.1 ml/min. of the liquid fatty acid mixture was used. The quantity of starting gas was varied according to the ozone concentration and the unreacted ozone was catalytically destroyed. The ozonolysis of technical oleic acid was carried out in the first microreaction system. In the second microreaction system, the ozonization products formed were cleaved under the effect of oxygen to form a mixture, with the principal constituents being azelaic and pelargonic acid. The results are set out in Table 1 (recording the mean values of three measurements). The yield of azelaic acid is based on the total input of the technical oleic acid used, i.e., including the saturated constituents. The volume/time yield is based on the empty volumes of the reactors used. The reaction mixture was analyzed by GC. Only minute traces of oleic acid were detected, so that the conversion under the selected conditions in the first reaction step can be regarded as a full conversion. After leaving the second oxidation reactor, ozonides could no longer be detected either. To monitor the GC analyses, relatively large quantities, from repeated test runs, were worked up as follows: the pelargonic acid was first distilled off and the azelaic acid was extracted with water and crystallized, yellowish crystals being obtained. After a recrystallization step, white crystals were obtained. The melting point was between 103° and 105° C., i.e., close to that of pure azelaic acid. GC analysis revealed purities of 97to 99percent. The yield of azelaic acid, based on the quantity of technical oleic acid used, was between 51.5 and 52.7percent of the theoretical and, by virtue of the excellent dissipation of heat, was almost independent of the ozone concentration in the starting gas. The yield, and hence the selectivity, for azelaic acid exceeded those of conventional processes for the selected starting composition.

[0152] 100 g of fatty compound and 1.1 g of tungstic acid (H2WO4; Merck 98percent) are introduced into a 250 cm3 jacketed reactor comprising a mechanical stirrer, and then stirred and heated at 70° C., said temperature being maintained by circulation of thermostatic water. The aqueous hydrogen peroxide is then added in weight contents which are variable according to the tests, via a peristaltic pump at variable addition speeds according to the tests. The reaction is stopped after 6 h, the aqueous phase is separated for analysis. The remaining organic phase is washed several times with hot water until aqueous hydrogen peroxide has disappeared from the washing water. [0153] The fatty substrates introduced come from the following sources: The fatty substrates introduced come from the following sources: [0154] oleonitrile (ON): Arkema with C16:0: 3percent, C18:0: 9.7percent, C18:1: 84.7percent, C18:2: 1percent (percent by weight).

The H2O2 concentration has an influence on the cleavage of the molecule treated (compare examples 1, 2, 3 and with example 4) resulting in heminitrile formation. [0159] The methyl oleate oxidation reaction results only in a very low conversion of the double bonds regardless of the operating conditions. This oleic acid derivative is not therefore suitable for the formation of diacids by oxidative cleavage. [0160] The oleic acid oxidation reaction allows a reduction in the iodine value of the medium (examples 9 to 12) and the formation of diacids, with a suitable H2O2 concentration.

Enzymatic hydrolysis of the sunflower oil is carried out, during which 22.5 kg of sunflower oil are placed in contact with a solution of a lipase (Lyven, Colombelles, France) of Candida cylindracea in distilled water (20.1 kg) with magnetic stirring at 40° C. for 5 hours. A fatty acid preparation is formed, the composition of which, determined by gas chromatography, is given in Table 1 below.TABLE 1 Fatty acid Composition by mass, percent Oleic acid, C18:1 87.6 Linoleic acid, C18:2 4.7 Palmitic acid, C16:0 3.5 Stearic acid, C18:0 3.1 Capric acid, C10:0 0.2 Others 0.9 21 g of this fatty acid preparation comprising 65 mmol of oleic acid are placed in a 250 ml three-necked round-bottomed flask equipped with a cooler, a mechanical stirrer and a heating device. There are added dropwise 2 ml of an aqueous solution of a quaternary ammonium salt (3.36 mmol) selected from the group formed of tetrabutylammonium chloride (n-Bu4NCl, Sigma Aldrich, Saint-Quentin Fallavier, France), tetrabutylammonium bromide (n-Bu4NBr, Sigma Aldrich, Saint-Quentin Fallavier, France), N-cetylpyridinium chloride monohydrate (C5H5N(n-C16H33)3Cl, H2O, Sigma Aldrich, Saint-Quentin Fallavier, France), Nmethyl-N,N,N-trioctylammonium chloride (CH3N(n-C8H17)3Cl, Sigma Aldrich, Saint-Quentin Fallavier, France), which is better known by the name "aliquat 336", and N,N,N,N-tetraoctylammonium chloride (N(n-C8H17)4Cl, Sigma Aldrich, Saint-Quentin Fallavier, France). An emulsion of the oleic acid and the solution of the quaternary ammonium salt is formed by mechanical stirring of the resulting mixture.There are prepared by mixing and stirring at ambient temperature for 30 minutes 4 g (1.2 mmol) of tungstophosphoric acid (H3PW12O40.15.4H2O) and 34 ml of 30percent oxygenated water (325.0 mmol) in 5 ml of distilled water. The solution of tungstophosphoric acid is added to the emulsion of the oleic acid and the quaternary ammonium salt. The addition of the solution of tungstophosphoric acid to the three-necked flask containing the emulsion is carried out dropwise over a period of 5 minutes. After addition of the solution of tungstophosphoric acid to the emulsion, the reaction mixture is heated to a temperature of 60° C. The reactor is placed and maintained under mechanical stirring (400 rpm) at a temperature of 85° C. and at atmospheric pressure for a period of

5 hours, and the reactor is then allowed to cool to ambient temperature again. The pH of the reaction mixture is adjusted to a value of pH=1 by addition of one volume of an aqueous solution of hydrochloric acid at a concentration of 4 mol/ l.In order to separate the carboxylic acids formed and the catalyst, one volume of ethyl acetate is added to the acidic mixture at pH=1 and then the reaction mixture is placed at a precipitation temperature (Tprecip, ambient temperature or temperature below 4° C.) so as to form a precipitate of the catalyst. The precipitate formed is washed with ethyl acetate. The aqueous phase containing the salts is separated from the organic phase in a separating funnel and is then washed with ethyl acetate. The different organic phases are combined, dried over ammonium sulfate and evaporated under reduced pressure.The samples obtained are analyzed and quantified by gas chromatography by means of a Varian chromatograph coupled to a flame ionization detector (FID) and equipped with a capillary column (L 50 m, 0.25 mm, particle size 25 -m) for analysis of the fatty acid methyl esters. The mobile phase is helium (Air liquide, France) at a pressure of 1034 hPa (15 psi) at the head of the capillary column. The temperature of the injector and of the detector is 250° C. The temperature of the oven containing the column is maintained at 100° C. for 5 minutes and is then increased gradually to 180° C. at a rate of 5° C./minute over 10 minutes and is finally increased gradually to 250° C. at a rate of 10° C./minute over 5 minutes and maintained at that temperature for 43 minutes.For the purposes of analysis, a solution of each sample is prepared at a concentration of 10 mg/ml in methyl tert-butyl ether (MTBE). The fatty acids are converted into methyl esters by treatment with trimethylsulfonium hydroxide. Pentadecanoic acid at a concentration of 2 mg/ml is added as internal standard. The results are presented in Table 2 below, in which Tprecip is the precipitation temperature, AZA percent and PEA percent represent the value of the synthesis and extraction yield of azelaic acid and pelargonic acid, respectively, relative to the starting oleic acid.TABLE 2 PEA, Catalyst prepared in situ Tprecip AZA, percent percent (n-Bu4N)3{PO4[WO(O2)2]4}; (A) 4° C. 77.6 80.9 (n-Bu4N)3{PO4[WO(O2)2]4}; (A) RT 72.9 73.9 (C5H5N(n-C16H33))3{PO4[WO(O2)2]4}; (B) 4° C. 81.5 86.1 (C5H5N(n-C16H33))3{PO4[WO(O2)2]4}; (B) RT 71.8 70.9 (CH3N(n-C8H17)3)3{PO4[WO(O2)2]4}; (C) 4° C. 78.5 82.0 (CH3N(n-C8H17)3)3{PO4[WO(O2)2]4}; (C) RT 71.3 77.2 ((n-C8H17)4N)3{PO4[WO(O2)2]4}; (D) 4° C. 73.2 76.5 An improved yield is observed for a precipitation of the catalyst carried out at a temperature of +4° C. in comparison with a precipitation of the catalyst carried out at ambient temperature.

As a result, the yield of nonanoic acid, which is monocarboxylic acid, was 87percent. In addition, the yield of azelaic acid was 19percent. The remaining product was triazelain when the reaction was terminated. Accordingly, it has been revealed that an oxidation reaction

Conditions & References 1 :The following substances were fed continuously to a CSTR with a working capacity of 80 l, equipped with stirrer and with an adequate temperature regulation system: methyl oleate (technical purity approximately 85percent; flow rate 10 kg/h); an aqueous solution of hydrogen peroxide at 60percent (flow rate 2.3 kg/h); tungstic acid (H2WO4) (flow rate 48 g/h). The reaction was conducted at a constant temperature of 62° C. under vacuum (absolute pressure of 0.10-0.20*105 Pa) to evaporate the water fed together with the hydrogen peroxide; the evaporated gas was collected and condensed (approximately 1 kg/h of water).FIG. 3 shows the hydrogen peroxide over-all concentration during step a).As can be seen in FIG. 3, the over-all hydrogen peroxide concentration in the reactor was constant at about 1.5 g/ kg.The intermediate product containing vicinal diols was continuously discharged from the reactor and fed to step b)

by means of a gear pump, adjusted to maintain a constant level in the reactor, with a flow rate of approximately 11.4 kg.Step b)Step b) was performed in a jet loop reactor with a working capacity of 80 l equipped with a 3 m3/h recirculation pump and heat exchanger. The intermediate product of step a) was continuously fed with a flow rate of 11.4 kg/h together with: cobalt acetate (Co(CH3COOH)2.4H2O, dissolved at 1.5percent in an aqueous current (approximately 2 kg/h); pressurized air (20*105 Pa; flow rate 12 to 15 kg/h). The air flow rate was adjusted to maintain a constant O2 content (approximately 10percent) at the reactor outlet.The reaction was conducted at 60° C., keeping constant the reaction volume to 50 l. The reaction time was about 3.5 h.The reaction mixture of step b) was continuously discharged from the jet loop reactor and fed to a decanter to separate the oily phase from the aqueous phase. Approximately 13 kg/h of oily product was obtained.Step (c)The separated oily phase was dried and degassed, and then transferred to a distillation column which allowed fractioning of the monocarboxylic acids, to separate the pelargonic acid from the lighter monocarboxylic acids. The main component of the lighter monocarboxylic acids fraction (byproducts of the oxidative cleavage reaction) was octanoic acid.Approximately 3.8 kg/h of vapor phase containing monocarboxylic acids (raw pelargonic acid), of which 3.5 kg/h are pelargonic acid with a titer of over 99percent, was obtained. The 3.8 kg/h current of raw pelargonic acid contained approximately 3.3percent of octanoic acid.An organic current of approximately 9 kg/h, containing as major component mono-methyl azelate, together with methyl palmitate, methyl stearate and esters of methyl dihydroxy stearate, was extracted from the bottom of the distillation column.Said organic current was then continuously fed to an emulsifier together with 18 kg/h of water. The emulsion was hydrolyzed by feeding it to three consecutive columns filled with acid ion exchange resin and heated at the temperature of 100° C. The total reaction time was 6 h.Each column was provided with a fractionating column on the top, to separate 1.1 kg/h of methanol from water. Approximately 8.5 kg/h of carboxylic acids were obtained from the bottom of the column, of which about 4.3 kg was azelaic acid.

2.2 g of 30percent H2 O2 in the presence of 0.2 ml of 75percent H2 SO4 are added to 5.7 g of cyclohexanonepropionitrile. The reaction is allowed to proceed for 10 minutes under stirring, and the mixture is then poured into 10 ml of acetonitrile containing 3 g of cupric acetate. 11 g of FeSO4.7H 2 O are added to this solution over a period of 15 minutes. The temperature rises spontaneously to 38° C., and stirring is continued for a further 30 minutes. After this period the solution is cooled and extracted with 50 ml of ethyl acetate. The solvent is evaporated, and 3 g of cyclohexanonepropionitrile and 2.7 g of an unsaturated acid product are obtained by fractional distillation. The conversion of the cyclohexanonepropionitrile is thus 47percent. The distilled acid product is dissolved in 10percent NaOH and heated under reflux for 2 hours. The solution is acidified, and the precipitated acid product is dissolved in ethyl alcohol. 0.1 g of Pd on carbon is added, and the mixture then subjected to hydrogenation at ordinary pressure and temperature until hydrogen absorption ceases. 3.2 g of azelaic acid are obtained, equal to a yield of 86percent with respect to the converted product.

View in Reaxys 1 : EXAMPLE 1 The acid product thus prepared is dissolved in 20 ml of methanol, and 0.1 g of Pd on carbon are added. Hydrogen is introduced at ambient temperature until 0.026 g have been absorbed. The methanol is evaporated to dryness, and the separated product is dissolved in 15 g of 10percent aqueous NaOH. The mixture is left under reflux for 2 hours, and is then cooled and acidified with 10percent sulphuric acid. 2.4 g of azelaic acid are obtained on crystallising the product from water. Patent; Brichima S.p.A.; US4322547; (1982); (A1) English View in Reaxys 1 : EXAMPLE 1 Conversion of the cyclohexanonepropionitrile 39percent. Yield of azelaic acid with respect to the converted product 87percent. The same example was repeated in an identical manner, but using 11 g of FeSO4.7H 2 O and 5 g of Fe2 (SO4)3 as catalyst. Only traces of azelaic acid were obtained, which were difficult to separate from a mixture of saturated and unsaturated acids containing 9 and 18 carbon atoms. Patent; Brichima S.p.A.; US4322547; (1982); (A1) English View in Reaxys 36 : EXAMPLE 36 This acid was mixed with water (400 parts by volume) and sodium hydroxide (20 parts by weight) and heated in an autoclave at 320°C for 1.5 hours. The autoclave was cooled and the contents filtered, after addition of a small amount of charcoal, in order to remove inorganic materials. The filtrate was acidified with concentrated hydrochloric acid and allowed to stand overnight, to give an aqueous suspension of azelaic acid. The azelaic acid was recovered by filtration and the aqueous mother liquor was extracted with diethyl ether. The ethereal solution was dried over sodium sulphate and the ether was evaporated off. The solid residue was combined with the azelaic acid recovered by filtration, and the product was dried in a vacuum oven to give 38.6 parts by weight of crude azelaic acid. Recrystallisation of the azelaic acid from toluene gave 31.0 parts by weight of crystals (melting point 107°-108°C), and a further 4.0 parts by weight (melting point 106°-107°C) were recovered from the toluene mother liquor. The yield of azelaic acid was 85percent calculated on the basis of the ethyl cyclo-oct-4-ene-1-carboxylate and 78percent calculated on the basis of initial cyclo-octadiene.
