Preparation of Dichloro diphenylsilane: The crude monomer can be obtained by chlorobenzene and silica powder in the presence of copper catalyst. Then we can get trichloro(phenyl)silane and dichloro diphenylsilane by rectification.

Uses of Dichloro diphenylsilane: It is used as raw  materials of silicone oil and silicone. it is also used in the production of silicone and siloxanes and silicones, methyl phenyl. In addition, it can react with biphenyl-2,2'-diol to get 6,6-diphenyl-dibenzo[d,f][1,3,2]dioxasilepine. This reaction needs solvent benzene by heating.

When you are using this chemical, please be cautious about it as the following:
It is not only harmful if swallowed, but also toxic in contact with skin. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. After contact with skin, wash immediately with plenty of soap-suds. If you want to contact this product, you must wear suitable protective clothing, gloves and eye/face protection. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.)
