Thermodn. parameters at infinite dilution for thirty-one organic solutes in a series of imidazolyl hydrogen sulfate ionic liquids (ILs) were determined by inverse gas chromatog. (IGC). The IGC characterization was carried out at temperatures ranging between 303.15 and 343.15 K for determining the Hildebrand solubility parameter (未2) as well as the Flory-Huggins interaction parameter (蠂12鈭?/sup>), the activity coefficient at infinite dilution (纬12鈭?/sup>), and the thermodn. functions. In addition, based on the 纬12鈭?/sup> results, the selectivity and capacity were directly calculated for two separation problems (hexane/benzene and hexane/thiophene). Under the different effects of the three ILs, it was found that the values of 蠂12鈭?/sup> and 纬12鈭?/sup> were significantly different for the solutes tested, but all the values follow a certain pattern: they increase with temperature or decrease with temperature As the temperature increased, the solubility parameters of the three ILs showed a linear decrease trend. The solubility parameters of the three ionic liquids at room temperature were obtained by extrapolation as 未2([BMIM][HSO4]) = 24.15 MPa1/2, 未2([HMIM][HSO4]) = 24.10 MPa1/2, and 未2([OMIM][HSO4]) = 23.66 MPa1/2. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Product Details of 478935-29-4).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Product Details of 478935-29-4
