METHOD OF PREPARING IRIDIUM-BASED SOLUTION AND UTILIZATION THEREOF AS CATALYST Russian patent published in 1999 - IPC

Abstract RU 2138328 C1

FIELD: liquid catalysts. SUBSTANCE: method is distinguished by that iridium compound is brought into contact with hydroiodic acid or its precursor or mixture of these compounds in liquid phase at HI/Ir molar ratio 1 to 20 in presence of solvent at total pressure 1 to 10 bar and temperature not exceeding boiling temperature of solvent utilized under contact conditions. Contact is accomplished under atmosphere of air, inert gas (argon or helium), nitrogen or hydrogen, or their mixture. EFFECT: simplified process. 8 cl
