This piece of equipment is usually used in azeotropic distillations.

Water was removed by azeotropic distillation to shift the equilibrium to the right.

This set of techniques are known as azeotropic distillation.

The hydrated solid can be dehydrated with heat or by azeotropic distillation.

This permits a better-defined separation upon azeotropic distillation at a lower boiling point.

A common historical example of azeotropic distillation is its use in dehydrating ethanol and water mixtures.

For this, a near azeotropic mixture is sent to the final column where azeotropic distillation takes place.

Further enrichment is only possible by absorbing the remaining water using other means, such as hydrophilic chemicals or azeotropic distillation.

In order to increase the rate of forward reaction, the formed water must be removed from reaction media by either azeotropic distillation or adsorption.

This complex can be dehydrated using a Dean-Stark trap by azeotropic distillation:

If azeotropic distillation is used to remove water, it will contain trace amounts of the material separation agent (e.g. benzene).

The first process, used in many early fuel ethanol plants, is called azeotropic distillation and consists of adding benzene or cyclohexane to the mixture.

Water removal by application of a vacuum or by azeotropic distillation is crucial to favor polycondensation over transesterification.

The reactants are in principle in equilibrium with the product, and water may be removed via an added drying agent or by azeotropic distillation.

One advantage of salt-effect distillation over other types of azeotropic distillation is the potential for reduced costs associated with energy usage.

In chemistry, azeotropic distillation is any of a range of techniques used to break an azeotrope in distillation.

This dehydration technology can account for energy saving of 3,000 btus/gallon (840 k J/L) compared to earlier azeotropic distillation.

This practice of adding an entrainer which forms a separate phase is a specific sub-set of (industrial) azeotropic distillation methods, or combination thereof.

Extractive distillation is similar to azeotropic distillation, except in this case the entrainer is less volatile than any of the azeotrope's constituents.

When an entrainer is added to a binary azeotrope to form a ternary azeotrope, and the resulting mixture distilled, the method is called azeotropic distillation.

The reaction steps are reversible reactions and the reaction is driven to completion by removal of water by azeotropic distillation, molecular sieves or titanium tetrachloride.

Pure (anhydrous) isopropyl alcohol is made by azeotropic distillation of the wet isopropyl alcohol using either diisopropyl ether or cyclohexane as azeotroping agents.

To break azeotropic distillations and cross distillation boundaries, such as in the DeRosier Problem, it is necessary to increase the composition of the light key in the distillate.

Drying can also be achieved by the use of in situ desiccants such as molecular sieves, or the use of azeotropic distillation techniques e.g. with a Dean-Stark apparatus.

The reaction can be driven to the acetal when water is removed from the reaction system either by azeotropic distillation or trapping water with molecular sieves or aluminium oxide.
