摘　　要：制备了以氯化亚锡为配体的铑催化剂,评价了其在乙酸甲酯羰基合成乙酸酐中的性能。该催化剂既表现了良好的稳定性,又保持了较高的催化活性,乙酸酐时空收率为8.07 mol/(L.h),催化速率为每g铑生成乙酸酐809g/h。A novel tin-contained rhodium complex catalyst was prepared, and its performances for synthesis of acetic anhydride by carbonylation of methyl acetate were evaluated. The catalyst exhibited high stability and catalytic activity with a space time yield of 8.07 mol/（L. h） , i.e., acetic anhydride forming velocity of 809 gram per gram rhodium per hour.
