Abstract

Halo-ethyl trimethyl ammonium halides are made by reacting a 1,2-dihaloethane with trimethylamine in the presence of an amount of water and at a temperature and pressure sufficient to form a homogeneous solution with at least part of the reactants in the absence of product, and sufficient to dissolve the product to form an aqueous layer containing the product and a separate layer containing a substantial portion of any unreacted starting material. Preferred reaction temperatures are 100-150 DEG C. If the reactant is 1,2-dichloroethane, 20-30% by weight water, based on organic reactants, is employed. Examples relate to the preparation of 2-chloroethyl trimethyl ammonium chloride.
