Seeking help regarding the excessive selectivity of by-products in the direct synthesis of phenylchlorosilane monomer
Thread Content
The direct synthesis of phenylchlorosilane monomer using silica powder and chlorobenzene results in an excessively high selectivity for by-products such as benzene and biphenyl; I would like to discuss this with experts who have experience in similar projects.
What is the selectivity for diphenyldichlorosilane among phenylchlorosilanes? The by-product benzene is relatively easy to separate and treat, right? Is the difficulty in the fact that biphenyl is hard to handle? What about polychlorinated biphenyls? In the domestic market, aren’t they just Dalian Yuanyong, Xinya Qiang, and Chenguang?
