Abstract

In general the reaction is applicable to secondary amines that readily form an N-methylol derivative with formaldehyde. Diphenylamine and similar very weakly basic amines which do not readily form N-methylol derivatives with formaldehyde fail to react. The formaldehyde used is preferably in the form of an aqueous 30-37% solution, but may also be used in the form of paraformaldehyde.
