A new method for the synthesis of 3-hydrazinopropyl trimethoxysilane

Abstract

A new method for the synthesis of 3-hydrazinopropyl trimethoxysilane is proposed. The method is relatively simple and is based on hydrosilylation like the synthesis of analogous aminosilanes. For drying allylhydrazine hydrate a new efficient silyl hydride base method is proposed. The product, a new hydrazino-ormosil (organically modified silicate), can be applied in chemical modification of SiO2 surfaces, thus offering an alternative to aminosilane modification, which is widely applied in several surface coating technologies.
