“…Fig. 1 illustrates that VLE data for methyl acetate + methanol measured in this work are in good agreement with those reported by M. C. Iliuta et al [5] and M. Topphoff et al [6]. Hence the apparatus is adequate to measure the VLE data of the systems containing ILs.…”

“…It is evident that the selection of a suitable entrainer is crucial in extractive distillation [2]. Traditional entrainers such as organic solvents [3] or inorganic salts [4][5][6][7] have been employed in separating the mixture of methyl acetate and methanol, but they often make the process complicated, long and huge emerge consumption. * Corresponding Author: Wenxiu Li, Email address: wenxli@126.com, Fax: 86-024-89383736…”

in Wiley Online Library (wileyonlinelibrary.com)Vapor-liquid equilibrium (VLE) and liquid-liquid equilibrium (LLE) data of binary and ternary acrylic systems were systematically measured. Subsequently, VLLE phase diagrams of binary systems, tridimensional VLE phase diagrams of methyl acrylate (MA)-methanol (Me)-H 2 O ternary system, and quaternary LLE phase diagrams of MA-Me-H 2 O-methyl acetate (MeOAc) system were constructed. These diagrams clearly demonstrated the effects of temperature on phase equilibrium. The experimental data was fitted by the NRTL and UNIQUAC models, and the best-fitted parameters were used to predict interaction properties of ternary and quaternary mixture. Therefore, the phase equilibrium data were provided as reference for the design of acrylic systems rectification or extraction process. Residue curve was mapped out for MA-Me-H 2 O system through Aspen plus software. Finally, using thermodynamics and residue curve as theoretical basis, two novel separation processes were proposed and applied to the quaternary acrylic systems.

“…One key issue in the extractive distillation process is to select an appropriate entrainer. In separating methyl acetate and methanol, some entrainers of organic solvent (e.g., amine, N , N -dimethylformamide, dimethyl sulfoxide, and N -methylpyrrolidone , ) and inorganic salt (e.g., LiC1, CaC1 2 , Ca(NO 3 ) 2 , ZnNO 3 , and MgCl 2 − ). The volatility of solvent and the corrosion and difficulty in recycling of salts are the problems.…”

Isobaric vapor−liquid equilibrium (VLE) values at 101.3 kPa of binary methyl acetate + methanol, binary methyl acetate + ionic liquids (ILs), binary methanol + ILs, and ternary methyl acetate + methanol + ILs are measured, where the ILs are 1,3-dimethylimidazolium dimethylphosphate ([MMIM][DMP]), 1-ethyl-3-methylimidazolium diethylphosphate ([EMIM]-[DEP]), and 1-butyl-3-methylimidazolium dibutylphosphate ([BMIM][DBP]). The azeotropic point of methyl acetate + methanol is removed with addition of ILs, and [MMIM][DMP] gives the largest effect, followed by [EMIM][DEP] and [BMIM][DBP]. Salting-out effect from ILs is observed where the relative volatility of methyl acetate is increased. The minimum amount of such phosphate ILs required to break the azeotropic point is remarkably less than that of some other ILs; also such phosphate ILs are fluorine-free and easily prepared with cheaper starting materials. The experimental VLE data are correlated well with electrolyte NRTL model.
