Introduction . Wiped film short path molecular distillation equipment can eliminate thermal decomposition, polymerization or metamorphic, so this technology has already become the most moderate separation purpose distillation method, particularly suitable for concentration, purification and separation of high molecular weight, high boiling point, high viscosity material …

Jan 01, 2022 Silicone oil - Standard. This product is a linear polymer of dimethylsiloxane, containing 97.0% to 103.0% of polymerized dimethylsiloxane. There are different viscosities due to different degrees of polymerization. According to the different viscosity, this product is divided into 20, 50, 100, 200, 350, 500, 750, 1000, 12 500, 30 000 ten models.

May 01, 2009 Molecular distillation equipment is widely used in the fine chemical, petrochemical, pharmaceutical, oil and grease, food processing and light industries as well as in scientific research to concentrate and purify organic chemicals of high molecular weight, high boiling point, high viscosity and poor heat stability.

May 13, 2021 Therefore molecular distillation is also called short path distillation. The intermolecular distance should be high which can be achieved by a very high vacuum (0.1 to 1.0 pascal) Apparatus: Falling film Molecular still or wiped film Molecular still: Principle:

Molecular distillation equipment is a special liquid-liquid separation technology that operates under extremely high vacuum. There are wiped film molecular distillation system, short path distillation, etc. ... and the weight of the materials delivered to the static liquid surface is reduced. The vapor will be dense in discrete condensers, and ...

Molecular distillation has found wide commercial application in the separation and purification of such normally non-distillable, high molecular weight, thermally unstable substances as vitamins A and E, industrial synthetics, plasticizers, fatty acid dimers, and the like.

Molecular distillation is a short-path distillation that works at a low-pressure vacuum. The whole process can be used for purification, concentration, and separation of the standard natural …

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 ...

Oct 23, 2021 One of the things that you have to ensure when purchasing or sourcing is to see if the product is a molecularly distilled fish oil. Molecular distillated fish oil goes through a process that removes heavy metals, pesticides and PCBs. All quality manufacturers sell a molecularly distilled fish oil to remove these contaminants before it goes on ...

Sep 01, 2021 Each crude citrus EO was divided into two fractions using a lab-modified molecular distillation apparatus. Colorless, low molecular weight volatiles with a longer free path reached the condenser plate while heated under vacuum. These collected in the distillate stream were named Fraction 1.

The method is extremely valuable for the distillation of compounds in the molecular weight range 250-1,000, which have volatilities too low for distillation to occur at practical rates in conventional * MS. received June, 1958 stills and a structure which is readily damaged on heating.

Wiped film molecular stills, on the other hand, are designed to move the material downwards through the system in a thin sheet that is heated in a homogenous fashion, providing optimized heat exposure time for all material. [email protected] 715-672-8760. EMAIL US.
