MCQs: Molecular distillation is? - (A) High temperature distillation - (B) For heat-sensitive materials
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, nutrients and polyunsaturated fats.
Molecular distillation occurs at low temperatures and reduces the problem of thermal decomposition. High vacuum also eliminates oxidation that might occur in the presence of air. The rate of evaporation is controlled by the rate at which the molecules escape from the free surface of the liquid and condense on the condenser. The effects of feed ...

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.
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.
