| titleOfInvention | Method for producing oxalate through CO gas phase coupling |
| abstract | The invention relates to a method for producing oxalate through CO gas phase coupling and mainly solves the technical problem of low objective product selectivity existing in the prior art. With the adoption of the technical scheme that the method for producing the oxalate through the CO gas phase coupling comprises the following steps that: mixed gas containing nitrite and CO is taken as a raw material, a fluidized bed reactor is adopted, and under the conditions that the reaction temperature is 100-180 DEG C, the volume airspeed is 500-10000 hour<-1>, and the reaction pressure is -0.08 MPa to 1.5 MPa, the raw material is in contact with an assistant selected from rhenium, cobalt or silver and a precious metal catalyst selected from palladium for reaction to generate the oxalate, so the problem is better solved. The method can be used in the industrial production for increasing the yield of the oxalate. |
