Abstract
This application relates to an improvement in the preparation of quaternary ammonium alkene halides which are used in the production of cationic starch. The quaternary ammonium alkene halide product is recovered in a water solution which reduces exposure to and handling of the product by production workers, both in the manufacturing plant and in its subsequent use in a starch processing plant.
