METHOD OF PRODUCING POLYMETHYLSILSESQUIOXANE HYDROGEL Russian patent published in 2020 - IPC C08G77/14 C08G77/04 C08G77/08 C08G77/16 C08G77/38 

Abstract RU 2714728 C1

FIELD: technological processes.

SUBSTANCE: present invention relates to production of organosilicon adsorbent. Disclosed is a method of producing polymethylsiloxane polyhydrate, involving hydrolysis of methyltriethoxysilane in ethanol in the presence of a catalyst with subsequent aging and washing of the hydrogel, where an alkaline catalyst is used and hydrolysis is carried out in an alkaline medium.

EFFECT: present method reduces consumption of organic solvent and increases adsorption capacity of product.
