Abstract

Process for the manufacture of quaternary ammonium compounds by reacting a compound having a terminal epoxy group with a tertiary amine which is partly present as the free amine and partly present in the form of a salt, followed by the addition of sufficient acid at the end of the reaction to complete salt formation of the quaternary ammonium compound.
