摘要

Improvement of carbonylation method of the methanol in order to produce acetic acid is disclosed. As for especially being disclosed, being the method of reducing the formation of iodide alkyl and C3-8 carboxylic acid permanganic acid restoration characteristic chemical compound (PRC) by removing from the light phase of the light fraction overhead stream which is condensed, (a) distilling light phase, the overhead stream which is rich in PRC profit; The method of including the fact that then it separates the water stream of one or more which and (b) at two continual stages extracts the third overhead stream at least with the water, contains PRC.
