Jiang, Haihua published the artcileVapor-Liquid Phase Equilibrium for Separation of Isopropanol from Its Aqueous Solution by Choline Chloride-Based Deep Eutectic Solvent Selected by COSMO-SAC Model, Quality Control of 598-50-5, the main research area is vapor liquid phase equilibrium separation isopropanol aqueous solution; choline chloride deep eutectic solvent COSMO SAC model.
To sep. isopropanol from its aqueous solution by distillation, the deep eutectic solvents (DESs) with choline chloride, which were screened using the COSMO-SAC mode, were applied to eliminate the azeotropic point. The charge d. distribution over the mol. surface was calculated for isopropanol, water, and DESs to analyze the interactions between different species. Based on the screening results, a DES consisting of choline chloride and triethylene glycol in a molar ratio of 1:3 was selected. To validate the selected DES for the separation of isopropanol from its aqueous solution, the isobaric vapor-liquid equilibrium (VLE) data for the system of isopropanol + water + DES were measured at a pressure of 101.3 kPa. According to the measured VLE data, the azeotropic point of isopropanol and water can be eliminated by the DES at a concentration of 10 wt %. Meanwhile, the thermodn. consistency of the VLE data was checked by the van Ness test. The non-random two-liquid model was employed to correlate the VLE data, which were in agreement with the measured VLE data.
Journal of Chemical & Engineering Data published new progress about Azeotropes. 598-50-5 belongs to class isoquinoline, name is 1-Methylurea, and the molecular formula is C2H6N2O, Quality Control of 598-50-5.
