Reactive distillation is used with reversible , liquid phase reactions.
Removing one or more of the products is one of the principles behind reactive distillation. However, caution must be taken that the reactants won't boil off before the products. For example, Reactive Distillation can be used in removing acetic acid from water. Acetic acid is the byproduct of several reactions and is very usefull in its own right. Derivatives of acetic acid are used in foods, pharmaceuticals, explosives, medicinals and solvents.
