Reactive Distillation in production of Acetate

Steps involved in the production of Ethyl acetate
In first step ethanol with acetic acid is feed into the pre reactor column. This reaction mixture is again added to the reactive distillation upper column with additional amount of ethanol is feed into the lower section of the column. The components are added in a way that the acetic acid and ethanol will pass over one another counter currently. The reaction mixture get collected at the top of the column which again undergo separation into water and organic phase using a decanter. On further distillation of organic phase. Ethyl acetate is obtained

The obtained acetate is of various degree of purity for the. Similarly Reactive Distillation can be used in the separation of acetic acid from water. While the derivative obtained from the reactive distillation of acetic acid can be further used in industries like foods, pharmaceuticals, explosives, medicinals and solvents.
