Acetic Acid Dehydration Via Heteroazeotropic Batch Distillation

3 ACETIC ACID DEHYDRATION VIA HETEROAZEOTROPIC BATCH DISTILLATION 

Although acetic acid and water do not form an azeotrope, the use of conventional distillation to separate these two components requires many equilibrium stages because the system has a tangent pinch on the pure water end of the xy diagram. Therefore, it is more economical to use a heterogeneous azeotropic distillation system with an entrainer for the separation.
