How Molecular Distillation History

Abstract Molecular distillation became an important industry during the past fifteen years, and has enabled many thermally sensitive materials to be prepared on a commercial scale, but the development of stills appears now to have reached a resting-point.

Feb 11, 2020 Summary: Molecular Distillation Apparatus is a special liquid-liquid separation technology. In a high vacuum state, it makes the average free path of vapor molecules larger than the distance between the evaporation surface and the condensation surface, so that the difference in evaporation rate of each component in the material liquid can be used to …

Feb 22, 2022 A distillation unit designed for short-path operations (molecular distillation) is made up of evaporator and internal spiral condensers placed in its center. The distance from the evaporation surface to the condensation surface does not exceed the mean free path of molecules, which means that, once evaporated, they reach the condensing surface ...

Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still. It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids.

Molecular distillation is mostly carried out in short path evaporators. While performing the evaporation the molecules are streaming directly from the heating surface to the internal condenser and there is no flow in the opposite direction. Essential conditions are:

Molecular distillation lowers the boiling point of liquids in a molecular still and is used to separate and remove undesirable molecules such as colorants, or to concentrate heat-sensitive molecules such as fatty acids. Molecular distillation also eliminates the low-boiling, ‘dirty’ top notes, resulting in a refined, super suave aroma. ...

Molecular distillation occurs at low temperatures and reduces the problem of thermal decomposition. High vacuum also eliminates oxidation that might occur in the presence of air. The rate of evaporation is controlled by the rate at which the molecules escape from the free surface of the liquid and condense on the condenser. The effects of feed ...

molecular distillation: Meaning and Definition of. Find definitions for: molec'ular distilla'tion. Pronunciation: a vacuum distillation in which the molecules of the distillate reach the condenser before colliding with one another.

Molecular stills were historically used by Wallace Carothers in the synthesis of larger polymers, as a reaction product, water, interfered with polymerization by undoing the reaction via hydrolysis, but the water could be removed by the molecular still.

Steam Distillation is a separation process for temperature sensitive substances. It is a particular type of distillation. Another way round it is a method for separating miscible liquid base depending upon their volatilities. For instance aromatic compounds. It plays a vital role in some industrial regions. Here no chemical reaction takes place.
