摘要: In this study, the extraction of thiophene from alkane compounds (hexane, heptane, and octane) was investigated by using 1-butyl 3- methylimidazolium nitrate ([Bmim][NO3]) 1-methyl 3-octylimidazolium ([Omim][NO3]). Liquid–liquid equilibrium (LLE) data for ternary systems ionic liquid + were reported at atmospheric pressure 298.15 K. The calculated selectivity solute distribution coefficient values experimental demonstrate that selectivities increase with increasing chain length while coefficients decrease. Moreover, containing [Bmim][NO3] are higher than those [Omim][NO3]. This implies is a more suitable solvent [Omim][NO3] desulfurization alkane. nonrandom two-liquid (NRTL) universal quasi-chemical (UNIQUAC) models used to correlate data. results show both can ...
