摘要
Water-immiscible, acid-soluble N-(aminomethyl)- alpha , beta -ethylenically unsaturated carboxamides such as N-(diethylaminomethyl)acrylamide are readily prepared by (1) reacting under acidic conditions a carboxamide such as acrylamide with a lower aldehyde such as formaldehyde and a moderately water-soluble secondary amine such as diethylamine and (2) recovering the resulting water-immiscible aminomethyl derivative of carboxamide from the acidic reaction mixture by adjusting the pH of the reaction mixture to a value of 7 or higher, whereby the water-immiscible derivative separates from the reaction mixture.
