METHOD OF PRODUCING ORGANOCHLOROSILANES BY GAS-PHASE THERMAL CONDENSATION AND REACTOR FOR REALISING SAID METHOD Russian patent published in 2013 - IPC C07F7/14 C07F7/12 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of producing organochlorosilanes. Disclosed is a method of producing organochlorosilanes by gas-phase thermal condensation of hydride chlorosilanes with chlorine-derivatives of olefins and aromatic hydrocarbons, involving heating starting reactants to temperature of 100-300°C, feeding the reactants into the mixing zone of a reaction space in separate streams in stoichiometric ratio and conducting the reaction in conditions that are close to adiabatic, without initiators or in the presence of an initiating additive at temperature of 450-600°C and then removing the mixture of reaction products from the output zone of the reaction space. Disclosed also is a reactor, having a housing which is a vertical cylindrical container-type apparatus, and pipes for inlet of reacting components and collecting the formed vapour-gas mixture of reaction products. The reactor volume is divided by a horizontal diaphragm with a centre hole into a top mixing zone, having pipes for inlet of reacting components and having a heat-insulation layer on the outside, and a bottom output zone fitted with a pipe for outlet of the vapour-gas mixture of reaction products and divided into sections by diaphragms with centre holes. Under each centre hole, there is tightly mounted baffle-distributor which is in form of a horizontal solid disc which overlaps the cross-section of the hole in the diaphragm in a plan view.

EFFECT: disclosed method is cheaper and more efficient than existing methods.
