Title:
METHOD FOR PRODUCING BIS(β-EPOXYPROPYL)SULFIDE AND BIS(β-EPOXYPROPYL)POLYSULFIDE
Document Type and Number:
WIPO Patent Application WO/2014/002876
Kind Code:
A1
Abstract:
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 hydrosulfide metal 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.
