    • A process of producing a silethylene oxide represented by the following general formula (1): ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 each represent a hydrocarbon group having 1 to 8 carbon atoms such as a methyl group, comprising the steps of thermally decomposing the hydrolyzate of 1,4-dichloro-1,1,4,4-tetrahydrocarbyl-1,4-disilabutane in the presence of an alkali, bringing the thermally decomposed product in contact with carbon dioxide and distilling the reaction mixture. According to this process, in the distillation, since polymerization or formation of 2,5-disilahexane-2,5-diol can be obviated, a purified silethylene oxide can be obtained in high yield. Further, the distillation apparatus will not be clogged with by-products.
    • 制备由以下通式(1)表示的聚环氧乙烷的方法:其中R 1,R 2,R 3和R 4各自表示具有1至8个碳原子的烃基如甲基,其包含 在碱存在下热分解1,4-二氯-1,1,4,4-四烃基-1,4-二硅烷的水解产物的步骤,使热分解产物与二氧化碳接触并蒸馏反应 混合物。 根据该方法,在蒸馏中,由于可以消除2,5-二脱氧己烷-2,5-二醇的聚合或形成,因此可以高产率获得纯化的硫醚环氧乙烷。 此外,蒸馏装置不会被副产物堵塞。
