Hydrochloric Acid → N-Hexadecylacrylamide

In a 250 ml capacity conical flask 13 g cetyl chloride (0.05 M), 3.5 g acrylamide (0.05 M) and 50 ml acetone were placed to obtain a clear solution. The solution was stirred with a magnetic needle at room temperature. 6.5 g anhydrous aluminium chloride (0.05 M) was added and the reaction mixture was stirred at room temperature. After 5 to 10 minutes of stirring, vigorous evolution of hydrogen chloride took place which ceased after about 5 minutes. Temperature of the reaction mixture was raised to 40 to 50° C. It was then cooled to room temperature and poured into 500 ml cold water. White product was precipitated. The product was isolated and purified by reprecipitation from acetone into cold water.
