Hydrochloric Acid → 3,5-Dinitrobenzanilide

Participants

Reaction Steps

To 71 g of aniline was added 22.3 g of powdery 3,5-dinitrobenzoyl chloride with stirring. Generation of heat was observed until the temperature reached 50° C. A yellowish orange paste was obtained. The paste was stirred for 10 minutes and, then, when the liquid reaction mixture was poured into 1 l of water and the mixture was rendered acidic by concentrated hydrochloric acid (35%), a white precipitate was formed. The precipitate was recovered by filtration and dried to obtain 23.58 g of 3,5-dinitrobenzanilide (the yield was 84.6%).
