二甲基二乙氧基矽烷在乙醚和適量的鹽酸下進行水解,可得八甲基圜四矽氧烷,產率為80%。對於用Grignard法製備二甲基二乙氧基矽烷,確定了原料用量的比例,並得到滿意的產率。

Dimethyldiethoxysilane was hydrolyzed to octamethylcyclotetrasiloxane with hydrochloric acid in the presence of ethyl ether. The yield was 80% of the theory. A procedure for the preparation of dimethyldiethoxysilane by the Grignard method with satisfactory yields was also reported.
