In methanol carbonylation reaction for the manufacture of acetic acid, [Rh(CO)2I2]- was adopted as catalyst. LaCl2, CeCl3 and NdCl3 were used as additives. The effect of different additives on the reaction performance was studied systematically. The experimental results show that the reaction system with the additives exerts better catalytic activity and selectivity. The space time yield of acetic acid reached 30mol/(L·h).
