60.5 g (0.5 mol) of benzaldoxime was suspended in 390 ml of 8N hydrochloric acid and chlorine gas was bubbled into the suspension while stirring and maintaining the reaction temperature at from 5° to 15° C. The oxime immediately showed a green color upon reaction with chlorine and, after allowing the reaction mixture to stand, pale yellow crystals of α-chlorobenzaldoxime precipitated. Filtration of the reaction mixture yielded 66 g of crystals having a melting point of 45°-47° C. Yield, about 84%.
