ABSTRACT:
A process for preparation of 2-methacryloyloxyethyltrimethylammonium chloride crystals in high yields from dimethylaminoethyl methacrylate and methyl chloride is provided. Reaction takes place in an organic reaction solvent. The product crystals formed are washed with a washing liquid which is a non-solvent for the product crystals but which is a solvent for the reaction solvent, reactants and impurities therein. The product crystals are 2-methacryloyloxyethyltrimethylammonium chloride monomers which can be polymerized or copolymerized with other vinyl monomers to prepare flocculants.
