Reaction Steps

A solution of hydroxylamine in methanol prepared as in example 31 was used (4.1 g NH2OH in 100 mL solution). The hydroxylamine solution (41 mL) was placed in a 250 mL Erlenmeyer flask furnished with magnetic stirring bar and was kept cooled in ice-water bath (about 10° C.). The pH was 7.6. A solution of benzoic acid (6.1 g; 0.05 mol) in absolute methanol (50 mL) was slowly added with stirring (pH 6.3). The clear mixture was then stirred for one hour at room temperature and then carefully evaporated to dryness. Hydroxylamine benzoate was collected as a white crystalline solid (7.5 g). Yield 96.8%.
