Abstract
In this work, the hydroxyl-functionalized ionic liquid [EtOHEIm][SCN] was synthesized and characterized by 1H NMR, 13C NMR, and IR. A scientific study of the viscosity of three dilute solutions (m = 0.0300–0.3000 mol·kg–1) of 1-hydroxyethyl-3-ethyl imidazole thiocyanate [EtOHEIm][SCN] in water, acetonitrile, and ethanol was carried out in the temperature range from 293.15 to 318.15 K at 0.1 MPa. The viscosity deviation, Δη, relative viscosity, ηr, and excess Gibbs energy of activation for viscous flow of mixtures, ΔG≠E proposed by our team, were obtained, and the related entropy and enthalpy were also discussed. The fitted coefficients of A and B from the Jones–Dole equation were applied to analyze and explore the interaction between [EtOHEIm][SCN] and solvents.
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.
