CATALYST FOR SYNTHESIS OF OXALATE VIA A CO COUPLING REACTION, A METHOD FOR PRODUCTION THEREOF AND USE THEREOF Russian patent published in 2019 - IPC B01J23/44 B01J23/00 B01J37/02 B01J37/08 C07C55/07 C07C67/36 

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst intended for synthesis of oxalate via CO binding reaction. Said catalyst comprises (a) an active component containing palladium (Pd) or an oxide thereof; (b) an auxiliary substance comprising an auxiliary element selected from the group consisting of nickel, cobalt, manganese, zirconium, cerium, lanthanum, molybdenum, barium, vanadium, titanium, iron, yttrium, niobium, tungsten, tin and bismuth; and (c) a carrier consisting of hollow microspheres of α-Al₂O₃. Also disclosed is a method of producing said catalyst and a method for use thereof in synthesis of oxalate in a gas-phase reaction between carbon monoxide (CO) and methylnitrite (MN).

EFFECT: reduced concentration of precious metal, high activity and stability of the catalyst.
