英文摘要	Acetic acid is an important bulk chemical and synthesis of acetic acid via methanol hydrocarboxylation with CO2 and H-2 is a very promising route. In this work, we studied the reaction over a number of catalytic systems. It was found that Rh-2(CO)(4)Cl-2 with 4-methylimidazole (4-MI) as the ligand was very efficient in the presence of LiCl and LiI. Acetic acid began to form at 150 degrees C. The TOF was as high as 26.2 h(-1) and the yield of acetic acid could reach 81.8% at 180 degrees C. The catalytic system had obvious advantages, such as simplicity, high activity and selectivity, milder reaction conditions, and less corrosiveness. The excellent cooperation of CO and Cl-in Rh-2(CO)(4)Cl-2, suitable basicity and aromaticity of the ligand 4-MI, and the hydrogen bonding ability of Cl-were crucial for the outstanding performance of the catalytic system. The control experiments showed that the reaction did not proceed via the CO pathway.
