The synthetic method of the phenyl silicone oil is divided into two methods: sodium metal conversion and cyclosiloxane polymerization.
The metal sodium conversion method is that methyl triethoxysilane, metal sodium and chlorobenzene are converted at a certain temperature to generate methyl phenyl diethoxy silane, then solvent is added, dimethyl dichlorosilane is dripped, hydrolysis and dehydration are carried out to obtain a mixed product, and then the mixed product is distilled to obtain a finished product.
The cyclosiloxane polymerization method synthesizes octaphenylcyclotetrasiloxane from diphenyl dichlorosilane, and then polymerizes the octamethylcyclotetrasiloxane and hexamethyldisiloxane end sealing agent.
