Jul 08, 2021 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.

Jul 15, 2020 Clear Cannabis was one of the first in the country to use molecular distillation for cannabis, adding proprietary flavors to the distillate it loaded into vape cartridges in California before licensing the name and process to other companies in other states. But molecular distillation is not for everyone or every product.

Jul 15, 2020 “Molecular distillation, from a chemistry perspective, is a physical process that relies on heating up the liquid or the resin to its boiling point and separating the constituents of that mixture based on boiling point,” Barone says. “Specifically, molecular distillation is doing it at a substantially reduced pressure.”

May 01, 2009 Molecular distillation (or short path distillation) is usually used for the distillation of thermally unstable materials, and it is the most economically feasible method of purification . It means that in the high vacuum condition, the distance between the evaporation surface and the condensation surface is less than or equal to the mean free ...

May 13, 2021 Working of Molecular Distillation: The vessel walls are heated suitably by a heating jacket. The feed flows down the walls and is spread to a film by the polytetrafluoroethylene (PTFE) wipers which move about 3 m/s giving a film velocity of about 5 ms. Due to heat liquid film evaporates and vapors hit the condenser.

Molecular distillation is usually carried out at a very low pressure. The material is not easily oxidized and damaged by operation. 5. Distillation liquid film is thin, heat transfer efficiency is high, film thickness is less than 0.5 mm. 6. Molecular distillation can separate substances which are not easily separated by conventional methods. 7.

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 ...

Oct 08, 2019 Molecular distillation uses a very high vacuum system which effectively reduces the pressure in the system to zero and allows compounds to essentially vaporize instantaneously. [1] The distillate proceeds in a continuous-feed fashion, and the rate of distillation depends on flow velocity and surface area of the heating and cooling blocks.
