Abstract

An object of the present invention is to provide a method for producing a sulfur-containing epoxy compound producing no scum-like insoluble matter. According to the present invention, a sulfur-containing halohydrin compound is dripped into and reacted with a mixed solvent containing an organic solvent and a basic compound to provide the method for producing the sulfur-containing epoxy compound. According to aspects of the present invention, the organic solvent is at least one type of compound selected from toluene and benzene, the basic compound is at least one type of compound selected from sodium hydroxide, potassium hydroxide and calcium hydroxide, and the reaction temperature is between −5° C. and 30° C.

First claim

The invention claimed is:

1. A method for producing a sulfur-containing epoxy compound, which comprises dripping a sulfur-containing halohydrin compound into a mixed solvent containing an organic solvent and an aqueous solution of a basic compound; and reacting said sulfur-containing halohydrin compound with said mixed solvent,
(A) wherein the sulfur-containing halohydrin compound is a compound represented by formula (1) below, and wherein the sulfur-containing epoxy compound is a sulfur-containing epoxy compound represented by formula (2) below:

wherein m represents an integer from 0 to 4, n represents an integer from 0 to 2 with the proviso that when m is 0, n is not 2;

wherein m represents an integer from 0 to 4, n represents an integer from 0 to 2 with the proviso that when m is 0, n is not 2; or
(B) wherein the sulfur-containing halohydrin compound is a compound represented by formula (3) below, and wherein the sulfur-containing epoxy compound is a sulfur-containing epoxy compound represented by formula (6) below:

wherein p and q each independently represent an integer from 0 to 4;

wherein p and q each independently represent an integer from 0 to 4; or
(C) wherein the sulfur-containing halohydrin compound is a compound represented by formula (4) below, and wherein the sulfur-containing epoxy compound is a sulfur-containing epoxy compound represented by formula (7) below:

wherein p and q each independently represent an integer from 0 to 4;

wherein p and q each independently represent an integer from 0 to 4; or
(D) wherein the sulfur-containing halohydrin compound is a compound represented by formula (5) below, and wherein the sulfur-containing epoxy compound is a sulfur-containing epoxy compound represented by formula (8) below:

wherein p and q each independently represent an integer from 0 to 4;

wherein p and q each independently represent an integer from 0 to 4.

2. The method for producing a sulfur-containing epoxy compound according to claim 1 , wherein the organic solvent is at least one type of compound selected from toluene and benzene.

3. The method for producing a sulfur-containing epoxy compound according to claim 1 , wherein the basic compound is at least one type of compound selected from sodium hydroxide, potassium hydroxide and calcium hydroxide.

4. The method for producing a sulfur-containing epoxy compound according to claim 1 , wherein the reaction temperature is between −5° C. and 30° C.
