Dialkyldialkoxysilane and synthetic method thereof

The invention relates to a synthetic method of dialkyldialkoxysilane, and concretely relates to a method for synthesizing dialkyldialkoxysilane from two different alkyl groups. R and R in the formula of dialkyldialkoxysilane are respectively C3C-6 cycloalkyl groups or alkyl groups connected with the silicon atom and having an alpha-position or beta-position containing a branch chain, and R and R are different; and R is a C1-C3 linear alkyl group. The synthetic method concretely comprises the following steps: heating a small amount of alkylogen R and metal magnesium powder to carry out a Grignard reaction, adding a halogenated hydrocarbon diluted by a diluent in a dropwise manner to obtain a Grignard reagent, adding the Grignard reagent to tetraalkoxy silane in a dropwise manner, heating a small amount of a halogenated hydrocarbon R and the metal magnesium powder after the above reaction ends to carry out a Grignard reaction, adding a reaction solution and a halogenated hydrocarbon R and solvent mixed solution in a dropwise manner, separating the above obtained synthetic solution to obtain a solid, and fractioning the solid to obtain a finished product which is the final product dialkyldialkoxysilane. The dialkyldialkoxysilane can substantially improve the isotacticity, the physical and mechanical performances and other performances of alpha-olefin polymers.

Silane compound and processes for the preparation thereof

Novel silane compound, alkoxy cyclopentyl dimethoxysilane, is prepared by reacting cyclopentyl trihalosilane with ROH and then with methanol, or by reacting cyclopentyl trimethoxysilane with ROH, wherein alkyl in the alkoxy or R in ROH stands for an organic group selected from the group consisting of sec-butyl, tert-amyl, cyclopentyl, oxa-3-cyclopentyl, cyclohexyl and 2-isopropyl-5-methyl cyclohexyl groups. The silane compounds are useful as a catalytic component for olefin polymerization and as a silane coupling agent.
