Process for reducing the free aldehyde content in N-alkylol amide monomers

摘要

In a process for the preparation of N-alkylol amide monomers wherein a polymerizable amide is reacted with an aldehyde, the improvement which comprises adjusting the pH of the resulting N-alkylol amide monomer to pH 10-11 and adding thereto an alkali or alkali earth metal borohydride at a temperature of -10 DEG to 20 DEG C. so as to convert the residual free aldehyde in the equilibrium mixture to the corresponding alcohol.
