Abstract
Effect of Hj impurity in feed gas on the coupling of CO with methyl nitrite (MN) to dimethyl oxalate (DM0) was studied. It was found that the adsorption order was H2>MN>DM0 on Pd surface of the catalyst When ri. in the reaction system increased to above a certain value, a large amount of methyl formate and some methanol would be formed, and DM0 yield and dimethyl carbonate formation decreased obviously. The mechanism of H; affecting the reaction was discussed. The lowest H2 concentration affecting the reactions was determined. Increasing the linear velocity of the reaclants was an effective way to inhabit H2 impact关键词
