ABSTRACT:
Process for manufacturing anhydrous 2-hydroxy-3-chlorophropane trialkylammonium chloride by conversion of trialkylammonium chloride with epichlorohydrin by forming an aqueous solution of trialkylammonium chloride in an organic solvent inert to epichlorohydrin, the solvent forming an azeotrope with ater which boils at temperatures up to the normal boiling point of the solvent, distilling off the azeotrope to form a suspension of trialkylammonium chloride in the solvent reaction product and reacting the reaction product in the solvent with epuichlorohydrin at a temperature of 20.degree. to 120.degree. C.
