A "catalyst for the synthesis of oxalic acid esters and its preparation method" developed by Jilin Petrochemical Research Institute has recently been granted a national invention patent.
Oxalate is an important chemical raw material and can be used as an intermediate of oxalic acid, ethylene glycol, oxalamide and the like. The catalyst is a supported catalyst with treated Al2O3 as a carrier, palladium as an active component and ruthenium as a promoter. It is used not only in the reaction of carbon monoxide and methyl nitrite to synthesize dimethyl oxalate, but also Reactivity and selectivity, and long life, stable reaction, easy to control.
