Abstract

The production of 3-mercapto-propanediol-1,2 is attained with good yields and in an industrially simple manner by reacting liquid hydrogen sulfide with glycidol under pressure, namely either in the presence of aluminum oxide or a sodium aluminum silicate, i.e., in heterogeneous phase or in the presence of an alkali or alkaline earth hydroxide dissolving in reaction medium, i.e. in homogeneous phase.
