FIELD: chemistry.SUBSTANCE: invention relates to a method of producing primary or secondary alcohols of general formula, where R=H: R=CH, R=CH: R=-CHCHCHCHor RR=-(CH)-, -(CH)-,,, which are widely used as intermediate products in organic synthesis and as solvents and extraction agents. The method involves hydrogenation of aldehydes or ketones with hydrogen gas in the presence of a catalyst. The aldehydes or ketones used are benzaldehyde, methyl butyl ketone, cyclopentanone, cyclohexanone, adamantanone-2 or DL-camphor, and the catalyst used is nickel nanoparticles obtained by reducing nickel (II) chloride with sodium borohydride in situ, and the process is carried out at hydrogen atmospheric pressure in a medium of isopropanol at temperature of 55-70°C for 8-10 hours.EFFECT: method enables to obtain the desired products with high output using readily available reactants.7 ex |
