羰基合成乙酸和乙酸酐的研究进展

Research Progress on Carbonylation Process for the Manufacture of Acetic Acid and Acetic Anhydride

详细介绍了甲醇羰基化合成乙酸和乙酸甲酯羰基化合成乙酸酐的过渡金属配合物催化的均相反应体系,包括碘化锂促进的铑配合催化体系,配体促进或稳定的铑配合催化体系,铱配合催化体系,对羰基合成乙酸和乙酸酐的反应过程和反应机理进行了比较。

Homogenous transition metal catalysts for carbonylation of methanol to acetic acid and carbonylation of methyl acetate to acetic anhydride are reviewed.The catalyst system includes lithium iodide promoted Rh-based coordination catalyst,ligand promoted and stabilized Rh-based coordination catalyst and Ir-based coordination catalyst.Further more,the reaction process and mechanism of carbonylation of methanol to acetic acid is compared with that of carbonylation of methyl acetate to acetic anhydride.
