METHOD OF PRODUCING CATALYST FOR PROTIUM-DEUTERIUM ISOTOPIC EXCHANGE AND ORTHO-PARA CONVERSION OF PROTIUM Russian patent published in 2012 - IPC B01J37/34 B82B3/00 B01J23/50 B01D59/30 B22F9/24 

FIELD: chemistry.

SUBSTANCE: invention relates to heterogeneous catalysis, particularly a method of producing a catalyst for protium-deuterium isotopic exchange and ortho-para conversion of protium. The method involves obtaining silver nanoparticles from a reverse micellar solution followed by deposition on a Al₂O₃ support. Silver ions are reduced chemically. The reducing agent used is quercetin. Silver nanoparticles are obtained by preparing a reverse micellar solution of silver from 0.02-0.5 M solution of sodium bis(2-ethylhexyl)sulphosuccinate in a nonpolar solvent, 0.003-2.0 M aqueous solution of AgNO₃ and 0.000075-0.0002 M quercetin solution. The obtained solution is treated with ultrasound to obtain a reverse micellar dispersion.

EFFECT: invention enables to obtain a catalyst for operation at temperatures maximally close to liquefaction temperatures of protium and deuterium.
