Abstract

An organosilicon compound containing carbonyloxyether bond is disclosed, which can be used to synthesize the organosilicon material containing carbonyloxyether bond and to modify the surface of meso-porous Si material. Its preparing process is also disclosed.

Description

technical field [0001] The invention relates to a new type of organosilicon compound containing a carbon oxygen ether bond, a synthesis method and an application thereof. The synthesis method of this kind of compound is to generate organosilicon compound through hydrosilation reaction of olefin. Silicones containing different numbers and types of carbon-oxygen ether bonds can be synthesized through different olefin substrates; or re-grafted onto the surface of silicon materials, thereby changing the properties of silicon materials. The modified silicon material can be used as a loaded catalyst for synthesizing precious metal catalysts. The modified silicon material is also potentially used in the adsorption of metals, the adjustment of the hydrophilic and hydrophobic surfaces of the material, and the phase transfer catalysis, which provides broad prospects for its industrial production. Background technique [0002] Since the MCM-4 mesoporous silicon material first reporte...
