Preparation of oligodimethyl methylthyenil siloxanes

01igodimethyl(methylthyenil)siloxanes are a mixture of oligomer homo-logue liquids with the following common formula  

01igodimethyl(methylthyenil)siloxane liquids are obtained by the joint hydrolytic condensation of dimethyldichlorosilane, methylthyenildichloro- 

Raw stock dimethyldichlorosilane [not less than 58% (weight) of chlorine, the density of 1.06-1.07 g/cm3] MTDCS [not less than 98% (weight) of the 190-200 °C fraction] trimethylchlorosilane [32.1-33.2% (weight) of chlorine, the density of 0.856-0.859 g/cm3] sulfuric acid (up to 70% concentration). 

Depending on the ratio of the parent components, one obtains liquids with different values of n and in. 

Moreover, in the process of IIMTC synthesis there are secondary reactions, which form cyclohexanes, hexamethyldisiloxane and hydroxy-containing oligodimethyl(methylthyenil)siloxanes.
