摘　　要：以[Rh(CO)2Cl]2为催化剂,以Sn、Pb、Cr、Zr金属盐作为添加剂,在催化甲醇羰基化制乙酸的反应中系统考察了不同添加剂对反应的影响.试验证明,含有添加剂的反应体系具有更高的催化活性和选择性,其中乙酸的时空收率最高达到40mol/(L·h)以上.In methanol carbonylation reaction for the manufacture of acetic acid, [Rh(CO)_2Cl]_2 was adopted as catalyst, and metal salts of Sn、 Pb、 Cr、 Zr was used as additives. The effect of different additives on the reaction was systematically studied. The experimental results show that the reaction system with the additives demonstrate better catalytic activity and selectivity. The maximum space time yield of acetic acid reached 40 mol/(L·h).
