CATALYST OF DIRECT SYNTHESIS OF TRIETHOXYSILANE AND METHOD OF ITS OBTAINING Russian patent published in 2012 - IPC B01J31/30 B01J35/10 B01J23/72 B82B3/00 B01J37/08 B01J37/16 C07F7/02 

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry of organosilicon compounds, namely to elaboration of efficient sulphur-containing catalyst, applied for direct synthesis of triethoxysilane from metallurgical silicon and ethyl alcohol, as well as to method of obtaining said catalyst. Described is catalyst of direct synthesis of triethoxysilane based on copper chloride (1), representing ultrafine copper powders (1), whose spherical aggregates have diameter from 600 nm to 3 mcm and consist of globules with diameter to 200 nm, which, in their turn, represent nanoparticles of copper chloride (1) with size to 20 nm. Also described is method of obtaining described above catalyst by reductive thermolysis of chelate copper complex, obtained in situ from copper chloride dehydrate (11) in polyol medium.

EFFECT: obtaining target product with selectivity above 80%.
