A molecular design method based on the COSMO-SAC - …

2016-3-23 · In this study, a molecular design method was used to select solvents for extractive distillation. A COSMO-SAC model was used to screen for prospective solvents from a wide variety of ionic liquids for extractive distillation. Based on the COSMO-SAC model, the σ-profile database of ILs was established.

Molecular Distillation Research Papers - Academia.edu

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
