醋酸是一种用途广泛的化工原材料,其最主要的制备方法是甲醇羰基法合成法。在铑-碘催化剂体系催化的甲醇羰基化制备醋酸的工艺中无可避免的就会在生产出的醋酸中引入一些杂质。本文就工业醋酸生产过程中杂质的产生原理和途径进行了介绍,并相应的对杂质的处理方式进行了研究。
Acetic acid is a widely used chemical raw materials, the most important preparation method is methanol carbonyl synthesis. In rhodium-iodine catalyst system catalyzed methanol carbonylation of acetic acid process will inevitably introduce some impurities in the production of acetic acid. In this paper, the production of industrial acetic acid impurities in the production of principles and ways are introduced, and the corresponding treatment of impurities were studied.
