実験手順
To 5 l of water warmed at 50° C. was 453 g (3 mol) of m-nitrobenzaldehyde added and then, 218 g (3.3 mol) of a 50% aqueous solution of hydroxylamine (manufactured by Nisshin Kako) was added dropwise under stirring and further, stirred at the same temperature for 3 hours. Thereafter the mixture was cooled to room temperature, filtered, washed with water and dried. 488 g of m-nitrobenzaldoxime was obtained. Yield 98%; M.P. 118°-121° C.
