Experimental VLE data for binary systems of ethanol or water with three 1-ethyl-3-methylimidazolium ionic liquids (ILs) containing different anions were measured at normal pressure using the Siwoloboff procedure. ILs selected in this study those that appear to be suitable ethanol−water mixture separation by extractive distillation. Measured vapor–liquid equilibria described extended Raoult's la...

• 3-Component Margules equation was used to predict vapor–liquid equilibria. Infinite dilution activity coefficients are the sole input for solvent pre-selection. Industrial cases were validate approach. Molecular solvents, ILs and DESs incorporated in screening. We present an easily accessible, open-access approach fast pre-selection of solvents extractive distillation at isobaric isothermal c...

Ionic liquids (ILs) have shown excellent performance in the separation of binary azeotropes through extractive distillation [1]. But role ionic liquid azeotropic system is not well understood. In this paper, COSMO-RS model was applied to screen an appropriate IL separate azeotrope ethyl acetate (EA) and ethanol 1-octyl-3-methylimidazolium tetrafluoroborate ([OMIM][BF4]) selected. The Quantum Me...

The seasonal variation of water soluble extractive alcohol soluble extractive and ether soluble extractive have been investigated in leaves, wood and bark of Sesbania grandiflora, Sesbania bispinosa and Sesbania cannabina. Comparative account of water soluble extractive of leaves, wood and bark of Sesbania grandiflora was showed high level (range 4.2 to 5.8 %) than Sesbania bispinosa (range 3.3...

There is mixed evidence regarding the relationship between the extractive intensity of economic activity and the level of human development. Some studies find that mineraland energy-intensive economies have higher levels of development than economies without a substantial extractive sector, whereas others find that they have lower development levels. Those that find the negative relationship co...

• F-gas + IL mixture equilibrium and mass transport properties are reviewed. Influence of molecular structure in solubility selectivity is discussed. Design absorption, extractive distillation membrane separations analyzed. Extensive database containing 5000+ data provided. Interest recovering reclaiming refrigerant gases growing as a consequence increasing concern about the high global warming...
