Sulfur-containing epoxy compound and its manufacturing method

The invention provides a sulfur-containing epoxy component which is stable and does not generate white turbidness when is stored at room temperature, and a method thereof. To solve the problem, the sulfur-containing epoxy compound is manufactured by using hydrogen sulfide or polythiol compound and epichlorohydrin which has a turbidity value below 1.0ppm while manufacturing 30 mass% methanol solution and the manufacturing method are used.

Method of Producing Thioepoxy Compound for Optical Material and Polymerizable Composition for Thioepoxy based Optical Material Comprising the Compound

The present invention relates to a thioepoxy compound from which a high-quality optical material having a good and clear color and causing no whitening can be obtained, and a polymerizable composition for a thioepoxy-based optical material comprising the same. The present invention provides a method for preparing a thioepoxy compound for an optical material, which uses an epichlorohydrin compound as a starting material, wherein the epichlorohydrin compound has a total content of specific impurities, including acrolein, allyl chloride, 1,2-dichloropropane and 2,3-dichloropropene, of 1 wt% or less. According to the present invention, it is possible to obtain a thioepoxy compound causing less coloration by adjusting the content of specific impurities in the epichlorohydrin compound. In addition, the resultant thioepoxy compound can be used to obtain a high-quality transparent thioepoxy-based optical material having a good color and causing no whitening. The thioepoxy-based optical material according to the present invention is useful for corrective lenses, sunglass lenses, fashion lenses, metachrosis lenses, camera lenses, and lenses for optical devices.COPYRIGHT KIPO 2016
