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 - or molecular - distillation allows the evaporation of heat sensitive products at operating pressures down to 0,001 mbar at short residence times. On a cylindrical heating jacket the product is distributed and turbulized by a wiping system. The evaporated fraction is condensed on a condenser installed in the center of the evaporator ...

Short Path Distillation Process. The short path distillation definition is a technique that encompasses a distillate (an already separated product by way of chemical application) traveling a short distance at a greatly reduced pressure.. The short path distillation procedure does not use solvents like other methods, as it instead uses a built-in heating system to melt …

Short Path Distillation. Short path distillation or molecular distillation is a liquid-liquid separation process for high boiling, High viscosity, and heat sensitive, readily oxidisable materials. In the process of short path distillation, molecules escape from warmer liquid on vessel surface towards a cooler surface inside a condenser.

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.
