摘　　要：进行了Pd/α-Al_2O_3催化剂上CO与C_2H_5OH气相催化偶合制草酸二乙酯的试验研究,并对自制的几种不同催化剂进行评选。结果表明,B_1型催化剂具有良好的催化活性和选择性。当SV为2500～4000h^(-1)时,草酸二乙酯的时空收率分别为310和450g/L·h。草酸二乙酯和碳酸二乙酯的总选择性在95％以上。B_1型催化剂具有良好的稳定性和工业开发价值。Diethyl oxalate was synthesized in a bench scale test by vapor catalytic coupling of carbon monoxide and ethyl alcohol on Pd/α-Al_2O_3, and the various preparation methods of catalyst were evaluated. The results showed that B_1 type catalyst possesses good activity and selectivity. The space-time yields of diethyl oxalate are 310 and 450g/L·h respectively for space velocities of 2500 and 4000h^(-1). The overall selectivity of diethyl oxalate and diethyl carbonate is more than 95%. The B_1 type catalyst beha...
