Procedure

A 20.6 g sample of sodium p-styrenesulfonate was dissolved in 100 g of water. 14.4 g of p-toluidine hydrochloride was added to the resulting solution to precipitate a solid. The solid was filtered and was dissolved in 100 cc of aqueous solution containing 20 cc of 28.8% NH3 solution. As a result, ammonium p-styrenesulfonate was obtained in a conversion of 76%.
