KnowraExtractive distillationLinked fromLinked fromThe 8 pages that link to Extractive distillation, each with the reason it gives.All 8Broader topic 2Related 3Compared with 3DistillationBroader topic: A solvent can alter relative volatility when ordinary distillation struggles.Fractional distillationCompared with: It helps separate close-boiling mixtures without relying on their unmodified equilibrium behavior.AzeotropeRelated: A selective solvent can help separate components constrained by azeotropic behavior.RefluxCompared with: It changes mixture behavior through solvent addition rather than reflux alone.ButadieneRelated: It helps isolate butadiene from other C4 hydrocarbons with similar boiling points.Azeotropic distillationCompared with: It is a closely related alternative that uses a different solvent and separation mechanism.Continuous distillationBroader topic: It extends continuous column separation when ordinary volatility differences are inadequate.Fractionating columnRelated: A solvent can overcome volatility limits that defeat ordinary column fractionation.
