Method for industrially producing dialkyl dialkoxy silane

The invention discloses a method for industrially producing dialkyl dialkoxy silane, which comprises the following steps: in the presence of a catalyst and a solvent A, heating brominated hydrocarbonA and metal magnesium to reflux, and initiating reaction to obtain a first reaction solution; synchronously and dropwise adding chlorinated hydrocarbon and brominated hydrocarbon B which are diluted by a solvent B into the first reaction solution, and continuing reaction to obtain a second reaction solution; dropwise adding the second reaction solution into alkyl trialkoxy silane, and carrying outreflux reaction to obtain a third reaction solution; and cooling the third reaction solution, carrying out solid-liquid separation, and finally, carrying out washing and rectifying to obtain the dialkyl dialkoxy silane. The Grignard reaction of the chlorinated hydrocarbon is promoted by utilizing the high activity of the brominated hydrocarbon, so that on one hand, the overall conversion rate ofthe Grignard reaction can be remarkably improved, byproducts are reduced, the yield of a final product is improved, and on the other hand, the production cost can be reduced.
