    摘要： The direct synthesis of methylchlorosilanes to react metallic silicon with methyl chloride in the presence of a copper catalyst yields a high-boiling fraction of methyl-chlorodisilanes as by-products. The invention provides a method for preparing monosilanes from the high-boiling fraction by reacting it with hydrogen chloride in the presence of an amine or amide catalyst. The reaction is effected under the condition that the amount of iron, aluminum, zinc, tin and compounds thereof present in the reaction system is less than the equimolar amount with the catalyst. This increases the conversion of disilanes into monosilanes.

    摘要： The present invention is a process for converting a high-boiling component resulting from the reaction of an organochloride with silicon into commercially more desirable monosilanes. The process comprises contacting the high-boiling component with hydrogen chloride at a temperature within a range of 250°C. to 1000°C. in the presence of a catalyst selected from activated carbon, platinum supported on alumina, zeolite, AlCl₃ and AlCl₃ supported on a support selected from carbon, alumina and silica.

    摘要： A process for converting a high-boiling component resulting from the reaction of an organochloride with silicon into commercially desirable monosilanes is described. The process comprises contacting the high-boiling component with hydrogen gas at a temperature within a range of 250°C. to 1000°C. Process yield may be improved by use of a catalyst selected from activated carbon, platinum metal, platinum supported on alumina, palladium supported on carbon, SbCl₅, H₂PtCl₆, BCl₃, AlCl₃ and AlCl₃ supported on a support material selected from carbon, alumina and silica. A preferred embodiment of the process is run at a gauge pressure of 1.7 to 6.9 MPa (250 - 1000 psi). This process is preferential for the production of diorganodichlorosilane in relation to organotrichlorosilane in the monosilane product.
