Separation of thiophene from heptane with ionic liquids

Experimental and theoretically study of interaction between organic compounds and tricyanomethanide based ionic liquids

“…Selectivities and capacities at infinite dilution are collected in [26][27][28][29][30][31][32][33].…”

“…Recently, Domanska et al studied the behavior of organic compounds with 1-butyl-1-methylmorpholinium tricyanomethanide and 1-butyl-1-methylpyrrolidinium tricyanomethanide [1][2]. The authors found that tricyanomethanide based IL showed much higher selectivity and slightly lower distribution ratio in comparison with other anions for extraction of thiophene from aliphatic hydrocarbons [3][4]. These works clearly show that this family of ILs may be used for the separation of sulfur-compounds and nitrogen-compounds from alkanes.…”

“…Among others, gas chromatography technique has been used to determine the physico-chemical properties (partition coefficients, activity coefficients, selectivity) of numerous ILs [5][6][7][8][9][10][11][12][13][14].…”

FeCl3 Based Imidazolium Ionic Liquids as Novel Solvents for Extractive–Oxidative Desulfurization of Liquid Fuels

“…Faced with continuing fuel quality challenges, the fundamental scientific research has begun to pay close attention to the extraction of sulfur compounds with ionic liquids (ILs), which have the potential for alternative and future complementary technologies for deep desulfurization [7,8]. Several technologies such as extractive desulfurization (EDS), selective adsorption, catalytic oxidation, and biodesulfurization have been applied.…”

Study of interaction between organic compounds and mono or dicationic oxygenated ionic liquids using gas chromatography

“…[1][2][3] Numerous works have shown that a large number of ILs exhibit selectivities and capacities better than the solvents typically employed to solve industrial separation problems. [4][5][6][7][8][9][10] For instance, Kekra-Krolik et al have shown that ILs have a good capacity for deep fuel desulfurization as well as for denitrogenation [11][12]. Ionic liquids can be also used for the separation of azeotropic mixtures.…”
