Method for removing methyldichlorosilane and silicon tetrachloride impurities in trimethyl chlorosilane
-
Paragraph 0093-0096; 0104, (2021/08/25)
The invention relates to a method for removing methyldichlorosilane and silicon tetrachloride impurities in trimethyl chlorosilane, which comprises a hydrosilylation reaction, a partial esterification reaction and a complete esterification reaction. Firstly, a mixture of trimethylsilyl chloride containing methyldichlorosilane and silicon tetrachloride impurities is added to a reactor for hydrosilylation reaction, and the reaction product enters a separation system. The silicon tetrachloride in the mixture is partially esterified and reacted by adding the low-carbon alcohol as an esterifying agent, and the reaction product enters a separation system. Finally, the partially esterified product is further fully esterified to valuable tetraalkoxy silicon products. The high-efficiency recycling of trimethylchlorosilane is realized, and high-value utilization is also realized.
Cyano-containing chlorosilane synthesis method
-
Paragraph 0018; 0019; 0020, (2017/08/29)
The invention belongs to the field of organosilicon materials and discloses a cyano-containing chlorosilane synthesis method. The cyano-containing chlorosilane synthesis method includes adding copper chloride, a tertiary amine derivative and cyano-containing olefins into a reactor, dropwise adding hydrogen-containing chlorosilane with stirring under protection of nitrogen at 0-10 DEG C, heating to reach 50-120 DEG C after dropwise adding, conducting holding reaction for 3-48 hours, cooling to a room temperature after reaction is completed, and collecting corresponding fractions through reduced-pressure distillation so as to obtain cyano-containing chlorosilane. The cyano-containing chlorosilane compound is synthesized by addition reaction between the cyano-containing olefins and the hydrogen-containing chlorosilane with the copper chloride as a main catalyst and the tertiary amine derivative as a cocatalyst by means of dropwise adding under the mild conditions. The cyano-containing chlorosilane synthesis method has the advantages of high efficiency, high product selectivity, safe and mild reaction conditions, simple and easily available catalysts and low cost.
