実験手順

52.9 g (0.35 mol) of p-nitrobenzaldehyde was dissolved in 100 ml of methanol and a solution of 27.8 g (0.38 mol) of hydroxylamine hydrochloride in 35 ml of water was added dropwise over 30 minutes while maintaining the temperature at 30° C. and then, stirred at the same temperature for two hours followed by dilution with 300 ml of water. White crystals deposited were filtered and dried to obtain 55 g of p-nitrobenzaldoxime. Yield 94.7%; M.P. 128°-131° C.
