Reaktionsschritte

151 g (1 mol) of p-nitrobenzaldehyde was dissolved in 350 ml of methanol and an aqueous solution of 80.3 g (1.1 mol) of hydroxylamine hydrochloride in 100 ml of water was added dropwise over 30 minutes while maintaining the temperature at 30° C. Thereafter the mixture was stirred at the same temperature for 2 hours and diluted with 1000 ml of water. White crystals deposited were filtered, washed with water and dried. Thus, 161 g of p-nitrobenzaldoxime was obtained. Yield 97%; M.P. 128°-131° C.
