The azeotropic mixtures such as cyclohexane–butanol, acetone–methanol, cyclohexane–acetone, ethyl acetate–methanol, benzene–ethanol, toluene–methanol etc., can be separated to obtain 100% pure main compound respectively in high separation efficiency. The separation efficiency could be affected by ...
Miscible liquids are separated via a type of distillation called fractional distillation. The mixture is typically divided into parts after a series of distillations and condensations. When the combination is heated to a specific temperature where some of the mixtures begin to eva...
As a result, feasible separations in distillation columns and the operating parameters required for these separations depend on the vapor–liquid equilibrium of the mixture to be separated. For ideal and nearly ideal mixtures the components can be ranked in order of their volatility, or, ...
Pervaporation is a membrane-based process that uses selective permeation through membranes to separate liquid mixtures. Because the separation process is not affected by the relative volatility of the mixture components being separated, pervaporation can be used to separate azetropes and close-boiling ...
acid and the substituted membranes have remarkable affinity for polar compounds or mixtures of polar and non-polar compounds such that azeotropic mixtures of organic compounds as well as close- boiling liquid mixtures can be easily separated at good permeation rates using the technique of pervaporation...
Despite its apparent simplicity, such distillation columns can exhibit an unusual behavior not observed in zeotropic distillation:\ud\ud- For some mixtures, separation as a function of reflux goes through a maximum. At infinite reflux, no separation is achieved.\ud\ud- In some cases, achieving ...

Stichlmair and Herguijuela enumerate some experience rules for entrainer selection that may be helpful at this stage (see Table 1).16 Table 1. Experience rules for entrainer selection Mixtures with a minimum-boiling azeotrope: Low boiler (lower than the original azeotrope) Medium boiler that ...
This invention relates to the separation of two closely related hydrocarbons from complex mixtures containing same, and in particular to the separation of two closely related diolefins such as isopren
