How Molecular Distillation Is Used

Molecular distillation - ScienceDirect. introduction molecular distillation is a high vacuum process, whereby material distils from an evaporating surface to a relatively cool condensing surface, positioned directly opposite to it, under such an operating pressure that the mean free path of the distilling molecules is greater than the distance between the evaporating and condensing …

Molecular Distillation - Relative Volatility - Brewiki

2022-1-6 · Even with molecular distillation, the rates of evaporation obtained are low when the vapor pressure is less than 0.01 mm. Hg abs. Thus for a material having a molecular weight of 400 and a vapor pressure of 0.01 mm. Hg at 100°C., the absolute evaporation rate by Eq. (15-3) would be only 0.02 X 10~s g. per sec. per sq. cm.

Molecular distillation

Molecular distillation is vacuum distillation below the pressure of 0.01 torr (1.3 Pa). Free molecular flow occurs in various processes such as molecular distillation, ultra-high vacuum equipment such as particle accelerators, and naturally in outer space.
