Direct Synthesis of AlkoxysilanesPurposeAlkoxysilanes are widely used as intermediates in various branches of the national economy:
· a binder for ceramic molds in precision casting; · silicone fluids, resins varnishes; · adhesion promoters; · cross-linking agents for compositions and coatings;
· raw material for semiconducting silicon production.
Development descriptionAlkoxysilane liquid-phase synthesis method through direct silicon interaction with alcohols was developed. The method merits in comparison with the conventional procedure of chlorosilane etherification with alcohols consist in environmental hazards decrease, increase of useful life of equipment due to the absence of corrosive hydrogen chloride, a possibility to obtain high-pure products.
