4 : Preparation of catechol EXAMPLE 4 Preparation of catechol 6.1 g (0.05 mol) of salicylaldehyde and 33 g of a 12.6percent strength (0.13 mol) aqueous hydrogen peroxide solution are reacted for 70 hours at 50° C. and worked up analogously to Example 1, but without addition of base. 5.4 g of a solid are obtained, which is identified as catechol by 1 H-NMR spectroscopy with reference to a comparison sample. (Purity determined by gas chromatography: 90percent; yield 88percent of theory). With dihydrogen peroxide Patent; Hoechst Aktiengesellschaft; US5364983; (1994); (A1) English View in Reaxys
