The distillates of destructive distillation processes are often of relatively low molecular weights.

Fractional distillation, often referred to as molecular distillation, or short path distillation, is a form of distillation used for the separation and purification of compounds.This is achieved by applying the concepts of evaporation and condensation, often referred to as distillation, in order to target specific “fractions” based on their varying boiling points.

Mar 04, 2020 Wiped film molecular distillation is a continuous mode operation, thus the feed, distillate and residue compositions remain constant for the entire run. Feed material, kept flowing at a fixed feed rate, enters a high vacuum heated boiling zone for a short residence time, where some portion of it is evaporated away and condensed.

May 01, 2009 Molecular distillation of bio-oil at 70 C, 100 C and 130 C were investigated in this study to explore the effects of the evaporation temperature on the separation of compounds. The bio-oil was divided into three fractions: light, middle and heavy fractions. All samples were kept under − 4 C in the refrigerator.

Molecular distillation is a distillation method operated under high vacuum. At this time, the average free path of the vapor molecules is greater than the distance between the evaporation surface and the condensation surface, so that the difference in the evaporation rate of each component in the liquid can be used for liquid mixtures.

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, purification, and concentration of natural products, complex and thermally sensitive molecules. It is especially ...

Molecular Distillation – Short Path Distillation. Molecular distillation is a short-term vacuum distillation, depicted by incredibly low vacuum pressure, 0.01 Tor, which is performed using molecular static. And, it is a procedure for dividing, cleansing, and converging common elements, compound, and thermally sensitive atoms, for example ...

Nov 03, 2014 Short path and molecular distillation were developed in the 1930s and 1940s mainly in the UK and in the USA. In short path distillation, the produced vapours do not have contact with the liquid any more. The number of theoretical stages is 1 at a small distillate rate and may rise up to 2.2 at a higher evaporation rate. A first short path ...

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. ...

Often, extracted material prior to distillation is in a range of 55-70% cannabinoid, and it is typical to distill this up to a range from 85-90+%, with beyond 97% being reported.
