Azeotropic and extractive distillations are both methods of separating mixtures.
Both of them also use a certain separating solvent to help in the process.
The main difference between the two is in the process of separating the mixture.

Extractive distillation is defined as distillation in the presence of a miscible, high-boiling, relatively non-volatile component, the solvent, that forms no azeotrope with the other components in the mixture. The method is used for mixtures having a low value of relative volatility, nearing unity.
