Ability of Optical Resolution of Zinc Oxide Powders Modified with Chiral Amino Acids

Abstract

When the powders synthesized by dry grinding of zinc oxide and chiral amino acids in a ball mill were stirred in methanol with racemic carboxylic acids, amino acids, epoxide, and sulfoxide, the corresponding optically active compounds were recovered. The ratio of equilibrium constant of each enantiomer, K_L/K_D, was determined to be Max. 3.40.
