Title:
CATALYST FOR SYNTHESIZING OXALATE BY CO COUPLING REACTION, PREPARATION AND USES
Document Type and Number:
WIPO Patent Application WO/2020/082199
Kind Code:
A1
Abstract:
The invention relates to a catalyst for synthesizing an oxalate by a CO coupling reaction. The catalyst comprises an active component, an auxiliary agent and hollow microspheres of α-Al2O3 as a carrier. The auxiliary agent may comprise 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. Also provided is a process for making the catalyst and a method for using the catalyst in synthesizing an oxalate in a gas phase reaction between carbon monoxide (CO) and methyl nitrite (MN).
