Abstract

PURPOSE: Inexpensive method of preparing highly pruified leucine in large quantities by the reaction of aminoacid mexture solution containing leucine with benzenesulfonic acid to form leucine benzensulfonate salt which is subsequently isolated and decomposed to give highly purified leucine.
