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, and a nonpolar solvent, isooctane, followed by deposition on a support, wherein reduction of the metal salt takes place upon reaction with quercetin; the support used is SiO₂ and 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 capable of operating in the temperature range of 77-110 K.
