| Abstract: | By means of XRD,BET and evaluating,it was investigated that the crystal type of supports and the kind of the promoter affect the coupling reactions of the synthesis of dimethyl oxalate from carbon monoxide and methyl nitrite.The results showed that the catalyst with α-Al2O3 as the support and La as the promoter showed good catalytic performance.The yield of dimethyl oxalate is 0.53 g/mL·h,and the conversion ratio of CO is 70%. |
