| Abstract: | In this paper,the methods of separation and recovery of acetic acid from aqu-eous solution are reviewed, involving distillation, azeotropic distillation, esterification andsolvent extraction,The characteristics and application scope of these methods are analysed.Itis suggested that low boiling solvent extraction-azeotropic distillation be applied to separateacetic acid from higher concentration aqueous solution and amine solvent extraction fromlower concentration one in full-scale application. |
