- Adding a substance that reacts and removes one component. e.g. CaO reacts and removes water from azeotrope of ethanol and water
- distillation with a third substance e.g. benzene in rectified spirit
- Fractional crystallization
- solvent extraction
- adsorption
- adding concentrated sulphuric and distil e.g. separation of azeotrope of nitric acid
