Phenyltrichlorosilane

CAS:: 98-13-5

MF:: C6H5Cl3Si

MW:: 211.55

Use：: The high-temperature condensation (HTC) technique proved to be very convenient and economical for the production of phenyltrichlorosilane and in recent years has become one of the main industrial techniques for its synthesis. The synthesis of phenyltrichlorosilane by HTC technique is conducted according to the reaction: HSiCI3 + C6H5CI （HCI） C6H5SiCI3 In this case, similarly to the vinyltrichlorosilane case, in the conditions of synthesis (600-640 C) there is a secondary reaction of reduction, which forms silicon tetrachloride and benzene. However, if the process is conducted in the presence of an initiator (5% of diazomethane), it is possible to reduce the temperature down to 500-550 C. Then the secondary reaction proceeds very slowly, which increases the yield of phenyltrichlorosilane by 1.5 times. To suppress the reduction process, one can also add benzene and silicon tetrachloride into the reactive mixture. It is also possible to boost the yield of phenyltrichlorosilane and increase the degree of the chlorobenzene transformation by using two subsequent reactors.
