  Direct synthesis of alkyldialkoxysilanes by the reaction of silicon, alcohol and alkene using a high-pressure flow reactor

  摘要：

  In the reaction of silicon, methanol and ethylene, use of a high-pressure flow reactor operating at 240 degreesC at 0.86 MPa of ethylene and 0.18 MPa of methanol gave a 33% selectivity for ethyldimethoxysilane, which was much higher than that using an atmospheric-pressure flow reactor (8%) or using an autoclave (4%). The selectivity increased proportionally with the ethylene pressure below 0.5 MPa. This indicates that the addition of ethylene or methanol to a surface silylene intermediate determines the selectivity and that the ethylene addition is a first-order reaction. Above 0.5 MPa the slope of the selectivity change was smaller. By feeding propylene instead of ethylene, n- and iso-propyldimethoxysilanes were obtained as organosilanes with 15 and 2% of selectivity, respectively. The reaction of silicon, ethanol and ethylene resulted in 28% selectivity for ethyldiethoxysilane at 0.99 MPa of ethylene and 0.21 MPa of ethanol at 240 degreesC. (C) 2001 Elsevier Science B.V.

  The liquid-phase reactions of silicon, methanol and ethylene in an autoclave gave ethylmethoxysilanes (HSi(C2H5)(OCH3)2 and Si(C2H5)(OCH3)3) besides HSi(OCH3)3 and Si(OCH3)4. The reaction conditions for obtaining a high selectivity for the ethylmethoxysilanes were examined. With the use of a high pressure of ethylene and a small amount of methanol in toluene as a solvent at 433 K, ethylmethoxysilanes

  在高压釜中进行硅，甲醇和乙烯的液相反应，除得到HSi（OCH 3）3以外，还得到乙基甲氧基硅烷（HSi（C 2 H 5）（OCH 3）2和Si（C 2 H 5）（OCH 3）3）。和Si（OCH 3）4。检查了获得对乙基甲氧基硅烷的高选择性的反应条件。通过在433K下使用高压的乙烯和少量的甲醇的甲苯溶液作为溶剂，以59％的硅转化率获得了26％的选择性的乙基甲氧基硅烷。硅与乙醇和乙烯的直接反应生成HSi（C2 H 5）（OC 2 H 5）2和Si（C 2 H 5）（OC 2 H 5）3。
