Benzanilide Schotten - Baumann reaction

Place 5-2 g. (5 ml.) of anihne and 45 ml. of 10 per cent, aqueous sodium hydroxide solution in a wide-necked bottle (or, bF not available, a conical flask), and then add 8 -5 g. (7 ml.) of benzoyl chloride, stopper, and shake vigorously for 10-15 minutes. Heat is evolved in the reaction. The crude benzoyl derivative separates as a white powder. When the reaction is complete (t.e., when the odour of benzoyl chloride can no longer be detected smell cautiously), make sure that the reaction mixture is

Schotten-Baumann reaction /shot-en bow-mahn/ A method for the preparation of N-phenylbenzamide (benzanilide) in which a mixture of phenylamine (aniline) and sodium hydroxide is stirred while benzoyl chloride is added slowly. The N-phenylbenzamide precipitates and can be recrystallized from hot ethanol ...
