Process for separation of dimethyldichlorosilane from methyltrichlorosilane |
摘要 |
A process for separating dimethyldichlorosilane from methyltrichlorosilane in a mixture. The process comprises contacting a mixture comprising methyltrichlorosilane and dimethyldichlorosilane with silica gel, where the dimethyldichlorosilane is selectively retained by the silica gel. The process provides for the recovery of a methyltrichlorosilane fraction reduced in dimethyldichlorosilane concentration. The present process is especially useful for removing low levels of dimethyldichlorosilane present as a contaminate in methyltrichlorosilane.
