ABSTRACT:
A process is provided for making D-2-phenoxy propionic acid by condensing in water an alkali metal salt of 2-chloropropionic acid which is dextro-rotatory in water with an alkali metal phenoxide of a halogen or methyl substituted phenol. The overall amount of water in the condensation mixture is not more than about 8 moles water per mole of said alkali metal salt of 2-chloropropionic acid in order to selectively produce the dextro-rotatory optical isomer.
