Abstract

The invention relates to a kind of complete equipment for continuously preparing phenyl chloro-silicane. It means to provide a kind of complete equipment that is characterized by no use of catalyst, short synthesis route and hihg productivity, and to solve technical problem of on-line collected carbon removal and only one temperature province in reaction device. Said complete equipment is characterized in that: it comprises pre-heating device A, tubular reaction device B and filtering and cleaning device C which are in cascade connection; the upper inlet A2 on pre-heating device is material inlet, the lower outlet A3 is connected thorugh lower inlet on tubular reaction device, the upper outlet of reaction device is connected to the inlet of filtering and cleaning device; and the jacket equipped on said three devices are connected with heat conducting medium.

Description

technical field [0001] The invention relates to chemical synthesis equipment, in particular to a complete set of equipment for continuous synthesis of phenylchlorosilane. Background technique [0002] The main technical content is to use liquid raw materials such as hydrogen-containing methyl chlorosilane and chlorobenzene to synthesize phenyl chlorosilane in the gas phase through high-temperature gasification, and then undergo purification, rectification and other processes to prepare raw material-grade phenyl-containing chlorosilane. Domestic and foreign technical data retrieval and market research, the main preparation methods and equipment of phenylchlorosilane are: [0003] ① American DOW CORNING company adopts Grignard method to produce (Chinese Patent No. CN3811629.4): [0004] <chemistry num="001"> <chem file="200610049367_CML001.XML" / > < / chemistry> <!--img id="idf0001" file="A20061004936700031.TIF" wi="453" he="25" img-content="drawing" img...
