甲醇制乙酸工艺中降低杂质离子浓度的研究进展
Progress in reducing the concentration of impurity ions in the methanol to acetic acid process
摘要
Abstract
Acetic acid is a key raw material for the synthesis of organic compounds such as ethylene acetate,acetate,acetic anhydride and chloroacetic acid.The preparation of acetic acid by methanol carbonylation is the current mainstream process,however,trace impurity ions in the reaction solution have a significant impact on the activity and stability of the catalyst.The sources of impurity ions and their negative impact on catalyst performance were analyzed using the current mainstream Cativa process(iridium-based homogeneous catalytic system)as an example.The currently adopted impurity ion treatment strategies and highlights the application of ion exchange resin technology in impurity ion removal were reviewed.Some references for the normal production of acetic acid prepared by methanol carbonylation were provided.关键词
