実験手順
9.7 parts of 2-nitro-4-dimethylaminobenzaldehyde is dissolved in 50 parts of ethyl alcohol and a solution of 4.1 parts of hydroxylamine hydrochloride and 5 parts of sodium acetate in water is added. After the mixture has been boiled for one hour it is suction filtered. 7.5 parts (71% of theory) of 2-nitro-4-dimethylaminobenzaldoxime is obtained having a melting point of 140° to 143°C: ##SPC18##
