近年来，由于我国经济的迅速发展，对醋酸、醋酐的需求急剧增加。如何结合国情，开发醋酸、醋酐生产新工艺，便成为一项战略性的研究课题。鉴于甲醇羰基化合成醋酸，醋酸的原料来自煤炭，而我国煤炭资源相对丰富，又由于目前甲醇产量过剩，积极开发甲醇下游产品，研究甲醇羰基
In recent years, due to the rapid economic development in our country, the demand for acetic acid and acetic anhydride has sharply increased. How to combine the national conditions, the development of acetic acid, acetic anhydride production of new technology, it has become a strategic research topic. In view of methanol carbonylation of acetic acid, acetic acid raw materials from coal, coal resources in our country is relatively rich, but also due to the current excess methanol production, and actively develop methanol downstream products, research methanol carbonyl
