| Abstract: | study is carried out on synthesis of oxalate, e. g. dimethyl oxalate (DMO), throughcoupling of CO with nitrous acid esters, e. g.CH3ONO, over Pd/α-Al2O3, hydrolysis ofdimethyl oxalate, and regeneration of the byproduced NO to CH3ONO. The catalyst activity is retained in 1000 hrs the average S/Tyield is 611. 5g DMO/L cat. h in 1000 hours,the yield of oxalic acid from hydrolysis is>98%, and NO recbvery is>95%. The mechanism of DMO formation via coupling of COwith CH3ONO is proposed. |
