  When the reaction of metallic silicon with methanol in the presence of a small amount of thiophene was carried out at 653 K, methyldimethoxysilane was formed together with trimethoxysilane and tetramethoxysilane, the selectivity for methyldimethoxysilane being 22%. Further adding a small amount of trioxane, trimer of formaldehyde, to the reaction system improved the selectivity for methyldimethoxysilane

  当金属硅与甲醇在少量噻吩存在下于653 K下反应时，与三甲氧基硅烷和四甲氧基硅烷一起形成了甲基二甲氧基硅烷，甲基二甲氧基硅烷的选择性为22％。进一步向反应体系中加入少量的三聚甲醛甲醛，即三恶烷，提高了对甲基二甲氧基硅烷的选择性。这表明由甲醇脱氢形成的甲醛参与了甲基二甲氧基硅烷的形成。硅与乙醇的反应还给出了乙基二乙氧基硅烷的14％选择性和43％的硅转化率。

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

  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.
