  • solubility of co2 in a Choline Chloride urea eutectic mixture
    Journal of Chemical & Engineering Data, 2008
    Co-Authors: Minqiang Hou, Buxing Han, Xiaoling Wang, Lizhuang Zou
    Abstract:

    The solubility of CO2 in Choline Chloride + urea eutectic mixtures was determined at 313.15 K, 323.15 K, and 333.15 K under pressures up to 13 MPa. The mole ratios of Choline Chloride to urea selected were 1:1.5, 1:2, and 1:2.5. The Henry’s constants and enthalpy of solution of the gas were calculated from the solubility data. The solubility of CO2 in the mixtures increased with increasing pressure, and the solubility is more sensitive to pressure in the low-pressure range. The solubility of CO2 in the mixtures decreased with increasing temperature at all the pressures. The enthalpy of solution is negative at all conditions.

  • Speciation of copper(II) complexes in an ionic liquid based on Choline Chloride and in Choline Chloride/water mixtures.
    Inorganic chemistry, 2012
    Co-Authors: Peter De Vreese, Neil R. Brooks, Kristof Van Hecke, Luc Van Meervelt, Edward Matthijs, Koen Binnemans, Rik Van Deun
    Abstract:

    A deep-eutectic solvent with the properties of an ionic liquid is formed when Choline Chloride is mixed with copper(II) Chloride dihydrate in a 1:2 molar ratio. EXAFS and UV–vis–near-IR optical absorption spectroscopy have been used to compare the coordination sphere of the cupric ion in this ionic liquid with that of the cupric ion in solutions of 0.1 M of CuCl2·2H2O in solvents with varying molar ratios of Choline Chloride and water. The EXAFS data show that species with three Chloride ions and one water molecule coordinated to the cupric ion as well as species with two Chloride molecules and two water molecules coordinated to the cupric ion are present in the ionic liquid. On the other hand, a fully hydrated copper(II) ion is formed in an aqueous solution free of Choline Chloride, and the tetrachlorocuprate(II) complex forms in aqueous Choline Chloride solutions with more than 50 wt % of Choline Chloride. In solutions with between 0 and 50 wt % of Choline Chloride, mixed chloro–aquo complexes occur. Up...
