Short Path Centrifugal Molecular Stills

Short Path Centrifugal Molecular Stills are designed for those classes of chemical compounds which decompose, polymerize, react or are destroyed by low pressure distillation. These laboratory and continuous production units for the distillation of thermally sensitive organic and silicone compounds are built in a vacuum range of 1 to 80 X 10-3 Torr in the molecular weight range of 150 - 4000.

High throughput rates are obtained for groups of compounds which include vitamins, epoxy resins, highly concentrated pure fatty acids, plasticizers, fatty acid nitrogen compounds, and a host of other heat sensitive materials which may require only deoderizing and decolorizing. Other achievements include high purity separations from excess reactants and catalysts.

High vacuum distillation is a safe process to separate mixtures of organic or silicon compounds. Using the heat of condensation as a prime body for radiant heat emission to the surface film on the evaporator, these stills maintain short residence time and low distilling temperatures.

For increased variance in the molecular weight, the material is fed to the center of a heated spinning disc. By centrifugal force, the material spreads in a film across the heated disc, which intimately faces a large condensing surface.

Condensation begins whenever a sufficient temperature differential occurs between evaporator and condenser allowing an infinite number of sets of operating conditions for every feed material.
