Title: PROCESS FOR PRODUCING 1,2-PROPANEDIOL
Abstract:
A process for producing 1,2-propanediol or optically active isomers thereof from a readily available starting material in high yields at a low cost. The process comprises catalytically hydrogenating a 3-halogeno-1,2-propanediol of general formula (I) in a C2 or higher alcoholic solvent in the presence of an at least equivalent of a base to give 1,2-propanediol of formula (II). In formula (I), X represents a halogen atom.
