WebThe most used way to separate homogeneous azeotropes is by adding an extra component (entrainer or mass separating agent) to facilitate the separation. Entrainers are also used to enable the separation of nonazeotropic mixtures where this is uneconomical (e.g., due to the presence of tangent pinch points, as in the case of water and acetone) or ... Webazeotropic mixture which is difficult to separate. The entrainer are specific to the mixture, benzene is used as entrainer for separating ethanol and water mixture but not for ethanol and ethyl methyl ketone mixture [1].

The addition of a material separation agent, such as benzene to an ethanol/water mixture, changes the molecular interactions and eliminates the azeotrope. Added in the liquid phase, the new component can alter the activity coefficient of various compounds in different ways thus altering a mixture's relative volatility. Greater deviations from Raoult's law make it easier to achieve significant changes in relative volatility with the addition of another component. In azeotropic di… WebJan 1, 2013 · When a binary mixture forms an azeotrope, it is not possible to accomplish its complete separation by ordinary fractional distillation.
