Methylphenyldichlorosilane is an important organosilicon raw material, which can be used for the direct synthesis of methylphenylalkoxysilane and methylphenylcyclosiloxane, and can also be used as methylphenylsilicone oil, methylphenylsiloxane One of the main raw materials for the synthesis of silicone resin and methyl phenyl silicone rubber. Methylphenylalkoxysilane is the main raw material for the synthesis of methylphenyl silicone oil and silicone resin, as well as a silane coupling agent for powder heat resistance modification. Methylphenyl cyclosiloxane can be used for the direct synthesis of methylphenyl silicone oil, methylphenyl silicone resin and methylphenyl silicone rubber, especially suitable for the synthesis of high phenyl content silicone oil and silicone rubber. The introduction of methylphenylsiloxane links into silicon-containing polymers can improve the high and low temperature resistance, radiation resistance, compatibility and compatibility with organic polymers and inorganic fillers of silicone materials. , nuclear industry, and other fields that require resistance to high, low temperature and radiation have huge application prospects.

    In recent years, with the domestic demand for high-performance phenyl-containing organosilicon downstream products, it has greatly promoted the development of upstream methylphenylsilicon monomers. Through continuous research on methylphenyl monomer and grade separation technology, the yield and product purity of existing methylphenyldichlorosilane have been greatly improved, which can be directly used for methylphenylsiloxysilane and methylbenzene. Synthesis of intermediate raw materials such as cyclosiloxane, and one of the important raw materials used as methyl phenyl silicone oil, methyl phenyl silicone resin and methyl phenyl raw rubber. It is especially suitable for the synthesis of methylphenylalkoxysilane and methylphenylcyclosiloxane without trifunctional impurities, and the obtained methylphenylcyclosiloxane can meet the requirements of high-performance high-phenylmethylbenzene Preparation of silica-based raw rubber.
