CATALYST AND METHOD OF DISMUTATION OF HYDROGEN-CONTAINING HALOSILANES Russian patent published in 2013 - IPC B01J31/02 B01J31/12 B01J37/00 C07F7/10 C07F7/20 B01D3/32 B01J8/02 C01B33/107 

FIELD: chemistry.

SUBSTANCE: invention relates to field of catalysis. Described is catalyst of dismutation of water and halogen-containing silicon compounds, which contains as carrier silicon dioxide and/or zeolite and at least one linear, cyclic, branched and/or cross-linked aminoalkyl-functional siloxane and/or silanol, which in idealised formula corresponds to general formula (II): (R²)[-O-(R⁴)Si(A)]_aR³·(HW)_W (II), where A stands for aminoalkyl residue -(CH₂)₃-N(R¹)₂ with similar or different R¹, representing isobutyl, tert-butyl and/or cyclohexyl, R² independent on each other represent hydrogen, methyl, ethyl, n-propyl, isopropyl and/or Y, R³ and R⁴ independent on each other represents hydroxy, methoxy, ethoxu, n-propoxy, isopropoxy, methyl, ethyl, n-propyl, isopropyl and/or -OY, with Y representing carrier material, HW represent acid, with W standing for halogenide, residue of silicic acid, sulphate and/or carboxylate, with a≥1 in case of silanol, a≥2 in case of siloxane and w≥0. Method of obtaining said catalyst, its application in process of dismutation and installation for dismutation with its application are described.

EFFECT: reduction of economical expenditures of dismutation process.
