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 NaCOuntil 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.12 cl, 9 dwg, 4 tbl, 24 ex |
