Oct 14, 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,” Be says. “Specifically, molecular distillation is doing it at a substantially reduced pressure.” Read the entire article
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.
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, purifiion and concentration of natural products, complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids.
Molecular distillation was studied for the separation of tocopherols from soya sludge, both experimentally and by simulation, under different operating conditions, with good agreement. Evaporator temperatures varied from 100°C to 160°C and feed flow rates ranged from 0.1 to 0.8 kg/h. The process pressure was maintained at 10 −6 bar, the
Abstract Molecular distillation was studied for the separation of tocopherols from soya sludge, both experimentally and by simulation, under different operating conditions, with good agreement. Evaporator temperatures varied from 100 degrees C to 160 degrees C and feed flow rates ranged from 0.1 to 0.8 kg/h.
This distillation process is classified as short path distillation and is also referred to as molecular distillation due to the minimal vapor/liquid interface. The technique and equipment are typically used to purify substances with low volatility and/or temperature sensitivity. Molecular distillation is a time-tested method.

Carotenoids and biodiesel from palm oil were recovered through a process involving neutralization and transesterifiion of palm oil followed by molecular distillation of the esters. The concentrated obtained contains more than 30,000 ppm of carotenoids and the distillate contains above 95% of light-colored biodiesel.
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. After a short introduction, the author discusses in turn the various forms of molecular still existing at the present time, …
Molecular distillation or wiped film distillation is a type of short-path vacuum distillation, characterized by extremely low vacuum, 0.01 torr or less, which is performed with a molecular still. It is a process of separation, purifiion, and concentration of natural products, complex and thermally sensitive molecules. It is especially
Molecular distillation can selectively steam out the target product, remove other impurities, and separate more than two kinds of substances at the same time through multistage separation; 4. The fractionation process of molecular distillation is a physical process, so it can well protect the separated substances from pollution and damage.
