Various metal organic frameworks combined with imidazolium, quinolinum and benzothiazolium ionic liquids for removal of three antibiotics from water

In this research, imidazolium, quinolinum and benzothiazolium based ionic liquids (ILs) were immobilized on a metal organic framework (MOF) by solvent impregnation or capillary action. The synthesized IL@MOF composite materials were characterized by FTIR, XRD, SEM and TGA methods and then applied in removal of tetracyclines (TCs) from aqueous samples. The presence of ionic liquids significantly improved the adsorption efficiency of the metal organic framework, with 82% or higher removal percentage was obtained for the three target TCs while the pristine MOFs adsorption efficiency was below 50%. This could be attributed to the ability of ILs to make complex interaction with target drugs via multiple intermolecular forces. Experimental results revealed the effects of three significant factors including pH, temperature and solid-liquid ratio, and optimum adsorption efficiency could be achieved at pH 8 and 30 °C when solid-liquid ratio = 1:2 was adopted. The adsorption kinetics was properly fitted with pseudo-second order model and Redlich-Peterson model could be used to describe the adsorption isotherm for three antibiotics; moreover, the adsorption was an endothermic and spontaneous process in nature. Finally, the adsorbed TCs could be desorbed efficiently and the performance of the IL@MOF sorbent was further verified by actual water samples.

Solubility of four novel Br?nsted-acidic ionic liquids with 8-hydroxyquinoline cation in six alcohols

The equilibrium solubility of four novel Br?nsted-acidic ionic liquids (8-hydroxyquinoline phosphate ([HOQu][H2PO4]), 8-hydroxyquinoline sulfate ([HOQu][HSO4]), 8-hydroxyquinoline methanesulfonate ([HOQu][CH3SO3]) and 8-hydroxyquinoline p-toluenesulfonate ([HOQu][p-TSA])) in six lower alcohols (methanol, ethanol, 1-propanol, 2-propanol, 1-butanol and 2-methyl-1-propanol) was measured at temperatures from (278.15 to 348.15) K using a static method. With increasing temperatures, the solubility of ionic liquids increased and some of them showed "temperature-sensitive" property. The solubility of ionic liquids is closely related to the polarity and molecular structure of the solvents together with the strength of hydrogen bonding between anionic group of ionic liquids and alcohols. The experimental solubility values were well correlated by the modified Apelblat equation and λh equation. The dissolution enthalpy (ΔdisolnS) and dissolution entropy (ΔdisolnH) were determined using the van't Hoff equation and the change of Gibbs free energy (ΔdisolnG) was calculated at T = 298.15 K. The results showed that the dissolution process was endothermic and entropy-driven.

8 - hydroxy quinoline sensitive ionic liquid preparation and its catalytic long-chain fatty acid b method of esterification of

The invention discloses a preparation method of a temperature sensitive ionic liquid, and a method for catalyzing long-chain fatty acid esterification by using the ionic liquid. A general formula (I) shown in the specification represents the structure of the temperature sensitive ionic liquid, the ionic liquid is formed by a 8-hydroxyquinoline cation and anions comprising a tetrafluoroborate radical, a methane sulfonate radical, a bisulfate ion and a dihydrogen phosphate radical, and the solubility of ionic liquid in ethanol is temperature sensitive. The introduction of a hydroxy group to 8-position of aquinoline ring greatly increases the acidity and improves the esterification reaction yield. The ionic liquid can be mixed with ethanol to form one phase at a high temperature, and the ionic liquid and a product rapidly separate to different phases at room temperature or a low temperature, so the whole reaction system ensures high catalytic efficiency of a homogeneous reaction and makes separation and recovery simple, avoids the limitations of limited two-phase catalytic efficiency and the disadvantage of difficult ion liquid recovery of homogeneous catalysis, and accords with the principle of green chemistry. The esterification yield of the esterification reaction of the long-chain fatty acid under the catalysis of the ionic liquid reaches 90.6-95.5%.
