ABSTRACT:
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.
