Molecular distillation is a special liquid-liquid separation technology. It is different from the traditional distillation which relies on the separation principle of boiling point difference, but relies on the difference of the mean free path of the molecular motion of different substances to achieve separation.Using the working principle of molecular distillation, our LMD series short …
Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below. It’s considered as the safest mode of separation and to purify the thermally unstable molecules and related compounds with low volatility and elevated boiling point. Wiped film short path molecular ...
Molecular distillation is considered as the safest mode of separation and to purify the thermally unstable molecules and related compounds with low volatility and elevated boiling point.

A high vacuum separatory distillation process for distilling high boiling, heat sensitive substances in which the distance from the liquid surface to the condensing surface is less than the mean free path. ... and/or residue from a later distillation zone is returned to an earlier distillation zone. 76: Including the ...
Molecular Distillation. Molecular distillation is a chemical separation process that uses low vacuum pressure while incorporating an appliance called a molecular still. This type of separation process is commonly known as the short path vacuum distillation. In these scenarios, the molecule of the distillate reaches the condense.
Oct 26, 2021 Molecular distillation technology can excellently protect the quality of polymer products, improve product purity, simplify the process, and reduce costs. 3. Extraction of lanolin.

EOs extracted from four citrus varieties, sweet orange, grapefruit, mandarin, and lemon, were separated into two fractions by molecular distillation. The composition, physicochemical properties, cleaning ability, and antimicrobial …
The bottom drain pipe is drained; the remaining liquid, the heavy molecules, are collected in a circular channel below the heating zone and then run out through a side drain pipe. Molecular distillation . Compared with conventional distillation, molecular distillation has the following characteristics: 1.
The molecular distillation system consists of a distiller with a wiper, a heating system, a cooling system and a vacuum system. The vacuum system consists of a mechanical pump (roots pump) and a diffusion pump, which is capable of keeping the static pressure as low as 0.1 Pa. The temperature of the evaporation system, pre-heating system and ...
The molecular evaporator is distinguished by its short residence time in the heat-exposed zone and the low operating temperature due to vacuum in the distillation space. As molecular distillation separates molecules based on their differences in mean free paths, molecules are separated. The molecules should be allowed to pass freely without ...
