Why Use Short Path Distillation? - Extraction Magazine

Dec 04, 2018 Short path distillations are normally employed when heat damage and decomposition resulting from the relatively long time the product must remain at temperature (in regular methods) results in unacceptable loss of compound. [1] The general idea being that if you reduce the distance the molecule must travel (path) before it evaporates, you ...

Short-Path Distillation Equipment Short Path Fractional Distillation

Short-path distillation is a distillation technique where the distillate travels a short distance. It separates the mixtures based on differences in their volatility in a boiling liquid mixture under reduced pressure. As the sample mixture is heated, its vapors rise a short distance into a vertical condenser where they are cooled by water.
