0. Azeotropic Distillation
Azeotropic distillation is carried out when we have a mixture of immisible liquid which cannot be seperated using simple distillation as the diffence in boling point is very low and such mixtures are called as azeotropic mixture. If we carried out simple distillation of the azeotropic mixture, vapor generated by heating the mixture will contain both the component, hence seperation though simple distillation method can’t be done. In this case, Azeotropic distillation process is carried out.
In the Azeotropic distillation method, in the mixture of supposing A and B, an additional substance i.e. C is added which has an ability to alter the activity coefficient of the components and herby change the relative volatility of the mixture. The third component added in the mixture is known as entrainer which will create either minimum-boiling with one of the components.

Azeotropik damıtma yönteminde, A ve B varsayımının karışımına, bileşenlerin aktivite katsayısını değiştirme kabiliyetine sahip olan ve karışımın nispi uçuculuğunu değiştirebilen ek bir madde, yani C ilave edilir. Karışıma eklenen üçüncü bileşen, bileşenlerden biri ile minimum kaynama yaratacak olan sürükleyici olarak bilinir.
