摘要： A sulfonated resin catalyst whose activity has lowered as a result of use in the polymerization of silicone oil is reactivated by washing the catalyst with a low molecular weight siloxane medium, volatilizing off the siloxane medium under atmospheric or reduced pressure, and removing water from the catalyst.

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.
