On some stages of the development of the chemistry of nitrogen-containing organosilicon compounds in Russia and its role in the creation of new products and materials

This article presents an analysis of the achievements in the field of chemistry and technology of organoelement compounds for the period from 1959 to the present. It is shown that the combined ammonolysis of various organochlorosilanes allows to obtain polyorganosilazanes, which are used as heat-resistant cold-curing adhesives for siloxane rubbers; that compounds containing Si–N bonds allow to create materials capable of operating at high temperatures, possessing increased thermal and chemical resistance, high mechanical strength, high electrical insulation, semiconductor and other valuable properties. The resulting elastomers are used in radio electronics, electrical engineering, transport engineering, construction and medicine, and the synthesized carbaminosilanes are widely used as coupling agents for glass fiber in the production of fiberglass, vulcanizing agents and catalysts for curing silicone compositions, hardeners for epoxy resins, water repellents and as raw materials in the creation of materials suitable for use in gas-separating membrane technology. The results of recent studies were: the development of a new, environmentally friendly method for the synthesis of silicon derivatives of amino alcohols and the creation of heat- and fi re-resistant casting compositions for sealing high-voltage and highfrequency equipment.
