Abstract

L(+)-Lysine-monohydrochloride of optical purity better than 99% is prepared by evaporating an unsaturated aqueous solution of L(+)- and DL-lysine monohydrochlorides of optical purity 80-99%.L(+)-lysine to a concentration of the L compound such that at a temperature lower than the evaporation temperature the solution would be saturated with L compound, cooling the solution to the lower temperature while seeding with DL-lysine-monohydrochloride, separating the precipitate of DL and some L compound, and recovering L(+)-lysine monohydrochloride from the mother liquor.
