METHOD OF PRODUCING ALKOXYSILANES Russian patent published in 2017 - IPC C07F7/02 C07F7/04 

FIELD: chemistry.

SUBSTANCE: one-step method of producing tri- and tetraalkoxysilanes is proposed, involving direct interaction of silicon with an appropriate aliphatic alcohol containing 1 to 4 carbon atoms, in the presence of a catalyst such as copper or copper chloride at a temperature of 200-300°C, which is carried out in the vibrating bed of milling bodies in the acceleration range of oscillations of 26.6 to 985.9 m/s².

EFFECT: method is chlorine-free process that meets modern environmental requirements, and ensures the production of the desired product in high yield and high conversion of the starting materials.
