Dimethyldichlorosilane is a tetrahedral organosilicon compound with the formula Si(CH 3) 2 Cl 2. At room temperature it is a colorless liquid that readily reacts with water to form both linear and cyclic Si-O chains. Dimethyldichlorosilane is made on an industrial scale as the principal precursor to dimethylsilicone and polysilane compounds.
Stock and Somieski completed the hydrolysis of dichlorosilane by putting the solution of H 2 SiCl 2 in benzene in brief contact with a large excess of water. [3] [5] A large-scale hydrolysis was done in a mixed ether/alkane solvent system at 0 °C, which gave a mixture of volatile and nonvolatile [H 2 SiO] n.

The chemical formula of PDMS is CH 3 [Si(CH 3) 2 O] n Si(CH 3) 3, where n is the number of repeating monomer [Si(CH 3) 2 O] units. [4] Industrial synthesis can begin from dimethyldichlorosilane and water by the following net reaction: n Si(CH 3) 2 Cl 2 + (n+1) H 2 O → HO[Si(CH 3) 2 O] n H + 2n HCl. The polymerization reaction evolves ...

[1] 2 CH 3 Cl + Si → (CH 3) 4−n SiCl n + other products. While this reaction is the standard in industrial silicone production and is nearly identical to the first direct synthesis of methyltrichlorosilane, the overall process is inefficient with respect to methyltrichlorosilane. [2]
