Absorption Separation of Binary Refrigerant Blends Using 1-Butyl-3-methylimidazolium Thiocyanate Ionic Liquid
Extractive distillation using ionic liquids (ILs) as an entrainer is a promising way to separate azeotropic or near-azeotropic refrigerant mixtures. The vapor–liquid phase equilibrium between the refrigerant and ILs is one of the essential properties to evaluate the separation performance. In this work, the solubility of difluoromethane (R32), pentafluoroethane (R125), 1,1,1,2-tetrafluoroethane (R134a), 2,3,3,3-tetrafluoroprop-1-ene (R1234yf), and trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) in 1-butyl-3-methylimidazolium thiocyanate ([C4mim][SCN]) ionic liquid was investigated. The isochoric saturation method was used for the solubility measurement, and the studied temperature range was from 283.15 to 323.15 K. In addition, the ideal selectivity at infinite dilution of [C4mim][SCN] for four refrigerant mixtures including R32/R125, R32/R1234yf, R134a/R1234yf, and R134a/R1234ze(E) was calculated and analyzed. Results show that [C4mim][SCN] can be considered as a potential entrainer for separation of R32/R125, R32/R1234yf and R134a/R1234yf mixtures.
期刊介绍：
The Journal of Chemical & Engineering Data is a monthly journal devoted to the publication of data obtained from both experiment and computation, which are viewed as complementary. It is the only American Chemical Society journal primarily concerned with articles containing data on the phase behavior and the physical, thermodynamic, and transport properties of well-defined materials, including complex mixtures of known compositions. While environmental and biological samples are of interest, their compositions must be known and reproducible. As a result, adsorption on natural product materials does not generally fit within the scope of Journal of Chemical & Engineering Data.
