摘要：
Optically active .beta.-halolactic acids can be produced by contacting an .alpha.,.beta.-dihalopropionic acid with 2-halo acid dehalogenase. When the pH of the reaction system is above 9, this process gives optically active glycidic acid. Treatment of the optically active .beta.-halolactic acid thus obtained with an alkali also gives optically active glycidic acid.
