FIELD: chemistry. ^ SUBSTANCE: invention relates to heterogeneous catalysis, particularly a method of producing a catalyst for ortho-para conversion of protium. Described is a method of producing a catalyst for ortho-para conversion of protium, involving obtaining metal nanoparticles in a reverse micellar solution, consisting of a metal salt solution, a surfactant in form of sodium bis(2-ethylhexyl)sulphosuccinate, a nonpolar solvent, isooctane, followed by deposition on an Al2O3 support, wherein reduction of the metal salt takes place upon reaction with quercetin; the metal salt used is RhCl3 or RuOHCl3 and reverse micellar solutions of rhodium or ruthenium are prepared with molar ratio of the aqueous metal salt solution to the surfactant ranging from 1:1 to 10:1; a water-alcohol solution is then added in amount of 5-50 wt %, a quercetin solution is added in amount of 0.5-5 wt % and ammonia solution is added in amount of 10-30 wt %. ^ EFFECT: obtaining a catalyst with high activity and meant for operation in the temperature range of 77-110 K. ^ 2 cl, 4 tbl, 4 ex |
