Dec 03, 2021 Double-salt ionic liquids (DSILs) or ionic liquid mixtures are green solvents used for extractive distillation, and their selection is the key problem in this process. A computer-aided molecular design method based on COSMO-SAC and genetic algorithm (GA) was proposed for the selection of DSIL solvents. Three models (SAC-mixture, SAC-CA, and SAC-ionic) were …

Molecular distillation is a technology made exclusively for liquid-liquid separation. While traditional distillation does so with the boiling point difference separation principle, this method separates substances at the molecular level. This allows for a safer and purer technique of distillation. This method also produces a shorter residence ...

Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still. It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and polyunsaturated fatty acids.

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. ... Art History ...
