COPPER-BASED NANOSIZED CATALYST, METHOD FOR PRODUCTION THEREOF AND METHOD OF PRODUCING ALCOHOL VIA HYDROGENATION OF CARBOXYLIC ACID USING SAME Russian patent published in 2015 - IPC B01J23/76 B01J23/80 B01J37/03 C07C29/149 C07C31/12 B82B1/00 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to copper-based nanosized catalyst with particle size 1-50 nm and a method for production thereof, which includes: dissolving, in an aqueous solution, a first component containing initial copper (Cu), a second initial component containing one or more metals selected from a group which includes a transition metal, an alkali-earth metal and a group IIIb metal, and a third initial component containing one or more elements selected from a group which includes alumina, silica, alumina-silica, magnesia, titanium dioxide, zirconium dioxide and carbon, mixing the obtained solution to obtain a mixed salt solution; precipitating the mixed salt solution to precipitate an initial catalyst by adding Na₂CO₃ until pH 4.0-5.0 is achieved and then adding NaOH until pH 7.0 is achieved; and washing and filtering the precipitated initial catalyst. The invention also relates to a method of producing an alcohol, which includes reacting hydrogen and a carboxylic acid, which contains a simple acid or a mixture of two or more acids, using the disclosed catalyst.

EFFECT: obtaining an effective catalyst for producing a simple alcohol or an alcohol mixture.
