Silicone oil is a kind of polyorganosiloxane with different polymerization degree and chain structure. It is hydrolyzed by dimethyl dichlorosilane and water to produce the initial condensation of the ring body, the ring body by cracking, distillation to produce a low ring body, and then the ring body, capping agent, catalysts on the polymerization together can be obtained a variety of different degrees of polymerization of the mixture, by distillation under reduced pressure to remove the low-boiling material can be produced silicone oil. The most commonly used silicone oil, the organic group is all methyl, called methyl silicone oil.
Organic groups can also be used other organic groups instead of part of the methyl group, in order to improve some of the properties of silicone oil and applicable to a variety of different uses. Common other groups are hydrogen, ethyl, phenyl, chlorophenyl, trifluoropropyl and so on. In recent years, organic modified silicone oil has been rapid development, the emergence of many organic modified silicone oil with special properties.
Silicone oil according to the chemical structure of methyl silicone oil, ethyl silicone oil, phenyl silicone oil, methyl hydrogen silicone oil, methyl phenyl silicone oil, methyl chlorophenyl silicone oil, methyl ethoxy silicone oil, methyl trifluoropropyl silicone oil, methyl vinyl silicone oil, methyl hydroxyl silicone oil, ethyl hydrogen silicone oil, hydroxyl hydrogen silicone oil, cyanide-containing silicone oil and so on. In terms of applications, there are damping silicone oil, diffusion pump silicone oil, hydraulic oil, insulating oil, heat transfer oil, brake fluid, etc.
