Procedure

151 g (1 mol) of m-nitrobenzaldehyde was added to 1 l of water warmed at 70° C. and then, added with 72.6 g (1.1 mol) of a 50% aqueous solution of hydroxylamine under stirring. The mixture was stirred at the same temperature for one hour and cooled to room temperature and then, crystals deposited were filtered and dried. Thus 160 g of m-nitrobenzaldoxime was obtained. Yield 96%; M.P. 118°-121° C.
