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 by reducing metal ions under the effect of y-radiation of 60Co in a reverse micellar solution consisting of a metal salt solution, a surfactant which is sodium bis(2-ethylhexyl)sulphosuccinate, and a nonpolar solvent, isooctane, followed by depositing on a support, wherein the support used is Sibunit, and the metal salt used is RhCl3 or RuOHCl3, and reverse micellar solutions of rhodium or ruthenium are prepared in molar ratio of aqueous metal salt solution to surfactant ranging from 1:1 to 10:1; a water-alcohol solution is then added in amount of 5-50 wt % and ammonia solution is added in amount of 10-30 wt %, followed by ultrasonic treatment, deaeration and exposure to y-radiation of 60Co with a dose of 1-40 kGy. ^ EFFECT: obtaining a catalyst with high activity and capable of operating in the temperature range of 77-110 K. ^ 2 cl, 4 tbl, 4 ex |
