    Difference Between Distillation and Extraction

    The key difference between distillation and extraction is that distillation follows heating of a liquid mixture and collecting the vapor of the liquid at their boiling point and condensing the vapor to get the pure substance whereas, in extraction, a suitable solvent is used for the separation process.
