Silicone oil is a kind of polyorganosiloxane with a chain-like structure of different polymerization degrees. It is obtained by hydrolyzing dimethyldichlorosilane with water to obtain the primary polycondensation ring body. The ring body is cracked and rectified to obtain the low ring body. The ring body, the capping agent, and the catalyst are put together to telogen to obtain a mixture of various degrees of polymerization. The silicone oil can be obtained by removing low-boiling substances by vacuum distillation.
