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 ...

Reactive Distillation - an overview ScienceDirect Topics

Reactive distillation (RD) is a well studied process-intensified technology where the interaction of chemical kinetics and vapor–liquid equilibrium is exploited through integration of reaction and separation in a single column. The in-situ removal of products for an equilibrium-limited chemical reaction in RD helps in realizing enhanced ...

Synthesis of Cyclohexene from Cyclohexanol -

Synthesis was done via simple distillation since distillation gives a relatively pure yield (Karesek-Clement, 1988). Phosphoric acid was added to cyclohexanol in a round bottomed flask to have the dehydration reaction which would yield to the cyclohexene. It was then distilled and the group was able to get 3 ml of yield.
