Abstract
The present invention makes it possible to provide a method for producing a polyfunctional sulfur-containing epoxy compound, the method being characterized in that a polyfunctional thiol is reacted with an epihalohydrin in the presence of a reducing agent to form a polyfunctional sulfur-containing halohydrin, which is then reacted with a basic compound. The reducing agent is preferably at least one selected from the group consisting of sodium borohydride, lithium borohydride, lithium aluminum hydride, diisobutylaluminum hydride, and hydrazine.
Claims7
A method for producing a sulfur-containing epoxy compound, which comprises:
- reacting a polyfunctional thiol compound having at least two thiol groups with an epihalohydrin in the presence of a reducing agent to form a sulfur-containing halohydrin, and then
- reacting the sulfur-containing halohydrin with a basic compound to form the sulfur-containing epoxy compound;
- wherein the polyfunctional thiol compound is at least one selected from the group consisting of bis(2-mercaptoethyl)sulfide, 4-mercaptomethyl-1,8-dimercapto-3,6-dithiaoctane, 4,8-dimercaptomethyl-1,11-dimercapto-3,6,9-trithiaundecane, 4,7-dimercaptomethyl-1,11-dimercapto-3,6,9-trithiaundecane, 5,7-dimercaptomethyl-1,11-dimercapto-3,6,9-trithiaundecane, 1,2,6,7-tetramercapto-4-thiaheptane and pentaerythrithiol;
- and
- wherein the reducing agent is at least one selected from the group consisting of sodium borohydride, lithium borohydride, lithium aluminum hydride, diisobutylaluminum hydride, and hydrazine.
