    • According to the present invention, a method for producing bis(β-epoxypropyl)sulfide or bis(β-epoxypropyl)polysulfide can be provided, which is characterized by comprising adding a metal compound selected from the group consisting of a metal hydrosulfide, a metal sulfide and a metal polysulfide to an epihalohydrin at −5 to 30° C. in such a manner that the molar ratio of the epihalohydrin to the metal compound becomes 5 to 20 to thereby cause the reaction of the epihalohydrin with the metal compound. In a preferred embodiment, the epihalohydrin is epichlorohydrin, the metal hydrosulfide is sodium hydrosulfide or potassium hydrosulfide, the metal sulfide is sodium sulfide or potassium sulfide, and the metal polysulfide is sodium polysulfide or potassium polysulfide.
    • 根据本发明,可以提供一种生产二((bgr-环氧丙基)硫化物或双(&bgr .-环氧丙基)多硫化物的方法,其特征在于包括加入选自金属氢硫化物, 金属硫化物和金属多硫化物以-5至30℃的表卤代醇的形式,使得表卤代醇与金属化合物的摩尔比变为5至20,从而引起表卤代醇与金属化合物的反应。 在优选的实施方案中,表卤代醇是表氯醇,金属氢硫化物是氢硫化钠或氢硫化钾,金属硫化物是硫化钠或硫化钾,金属多硫化物是多硫化钠或多硫化钾。
