Acetic acid is a kind of important chemical raw materials， in organic synthesis and acetic acid production process produces a large number of low concentration of acetic acid Acetic acid fermented liquid and the purification of coarse product of the production technique and economic performance has important influence， but also for the environment protection and resource utilization and great value， so separation recycling acetic acid to industrial production to have the important The domestic and foreign research of acetic acid solution separation method are many， this article through to acetic acid process analysis of the present status of study separation， and relative separation process and summarizes， and including ordinary distillation， boiling distillation method of and solvent extraction， adsorption， neutralization， esterification method and the combined use of method of the main separation method， are Then from ?
