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.
Claims24
In a process for the production of 3-mercapto-propanediol-1,2 by the reaction of hydrogen sulfide with glycidol in the presence of a catalyst, the improvement comprising reacting liquid hydrogen sulfide with glycidol under pressure sufficient to keep the hydrogen sulfide in liquid form and wherein the reaction is carried out in heterogeneous phase with montmorillonite or hydroxysodalite as a solid catalyst at 30.degree.-150.degree.
