Conditions & References 1:1 Mixtures were treated mechanochemically under an argon atmosphere. The powders were ball-milled for 5 min at 350 rpm followed by abreak of 3 min, to prevent sample overheating and possible decomposition of products. The milling program was repeated 12, 36 or 72 times to establish an effective ball-milling time of 1, 3 or 6 h, respectively. in neat (no solvent), Time= 1h, Inert atmosphere, Milling, Mechanism, Time Møller, Kasper T.; Grinderslev, Jakob B.; Jensen, Torben R.; Journal of Alloys and Compounds; vol. 720; (2017); p. 497 - 501 View in Reaxys H

Conditions & References 2.2 Synthesis of NaBH4 The stoichiometric Mg powders, Mg2Si powders and NaBO2·2H2O powders were placed into a stainless steel reactor and ball milled in a vibrational ball mill (QM-3C, Nanjing, China). The mixture of Mg, Mg2Si and NaBO2·2H2O (0.9:1.8:1M ratio) was ball milled at 1200 cycles per minute. Each sample was obtained by ball milling 1g of reactants (the mixture of Mg, Mg2Si and NaBO2·2H2O), which were loaded into the jar, with a ball to powder ratio of 50:1at ambient temperature. In each experiment, the powders obtained were preserved and manipulated inside a glove box under a high purity argon atmosphere with O2 and H2O levels below 0.1ppm.

Synthesis of NaB3H8 Solvent-free NaB3H8 was synthesized according to a published literature procedure[21]. A Na/Hg amalgam was reacted with THFBH3 under nitrogen to form NaBH4 and NaB3H8. After removal of THF and redissolution in diethyl ether, NaBH4 was removed by filtration. The filtrate was concentrated under vacuum to an oil from which NaB3H8 precipitated upon addition of dichloromethane. Approximately 4.5 g of the white powder was recovered by filtration and vacuum drying. It is notable that Titov has reported the preparation of a variety of cationic octohydrotriborates, i.e., lithium, potassium, magnesium, calcium and strontium, as solvates of dioxane or diglyme [22], while Chong et al. have prepared the unsolvated Mg(B3H8)2 by a diborane-free pathway by thermal decomposition of Mg(BH4)2 [23].

Conditions & References 1-4; 1 : Example 1 This example serves to con effects of the preferred embodiment stated above. 0.35 g of powdery sodium metaborate of average particle diameter of 50 μm and 0.51 g of powdery magnesium of average particle diameter of 100 μm are fully mixed to a mixture and the mixture is filled in a reaction tube made of stainless steel. Then, after hydrogen gas is fed to the reaction tube at 400° C. under hydrogen pressure 2.3 MPa, temperature in the reaction tube or of hydrogen gas is raised to 550° C. The reaction quickly progresses when the temperature becomes over 500° C. With analysis by hydrogen generating method with hydrolysis or iodometric titration, yields are obtained during a period from start of reaction to three hours thereafter. The result is shown in FIG. 2. For example, 67percent yield is shown 2 hours after start of reaction. Percent yield is obtained by actual mol amount produced of product/theoretical reaction mol amount.x.100. Then, it is confirmed that sodium borohydride can be obtained with high yield.
