Recovery of dilute acetic acid via esterification reaction catalyzed by Amberlyst 15
The recovery of acetic acid from its dilute aqueous solutions is a major problem in both petrochemical and fine chemical industries. The conventional physical separations such as distillation and extraction suffer from several drawbacks. In the present work, the esterification reaction of dilute ace...
