In this paper,the influence of reaction conditions,such as CO pressure,reaction temperature and the solvent on the products of methanol carbonylation in IrCl 3·nH 2O and H 2IrCl 6·nH 2O catalytic systems was studied.

The report about methanol chemistry progress is related methanol carbonylation to acetic acid;methanol dehydrogenation (or carbonylation)to methyl formate;methanol oxidative carbonylation to dimethyl carbonate;synthesis of aromatic hydrocarbons,trimethyl orthoformate and methyl acetate;and new technology in selective production of dimethylamine and methylene chlorid

The both producing of acetic acid and anhydride acetic acid by methanol carbonylation is important,as well as the study of new technology.

Effects of preparation factors on the performance of Ni/AC catalysts for vapor phase carbonylation of methanol;

The process of carbonylation of methanol to methyl formate is simulated in this paper.

A mechanism model was built, and a whole flow emluator was developed on the base of 200 thousand tons per year of acetic acid through low-pressure methanol carbonylation of a chemical plant.

The effect of Ni/CNTs and Ni/AC catalyst for methanol vapor-phase carbonylation under atmospheric pressure were compared,and results showd that the Ni/CNTs catalyst was activer than Ni/AC catalyst.
