CDCl3 δC 77.0 ppm), CD3OD (CD3OD δH 3.31 ppm, CD3OD δC 49.0 ppm, DMSO-d6 δH 2.50 ppm, δC 39.52 ppm). 1H-NMR (DMSO-d6, 400Hz):- δ (ppm) 3.95 (s, 3H), 4.90 (d, 2H), 5.33 (m, 2H), 6.12 (m, 1H), 7.85(s,1H), 7.90 (s,1H), 8.71 (s, 1H), 9.94 (s, 1H). 2.2 Property and gas solubility measurements The densities of the solutions were measured by an Anton Paar DMA 4100M vibrating-tube densimeter with a precision of 10-4 g·cm-3. The accuracy of the temperature measurements was 0.05 K. The uncertainty in the density measurements was estimated to be roughly around 5 10-4 g·cm-3. The viscosities of the solutions were measured by Bohlin CVO 100 rheometry. A cone-on- plate geometry was used with a 1o cone angle and 20 mm cone diameter. The lower plate had a diameter of 60 mm. During the experiments, the temperature was maintained at a temperature interval of 293.15 to 333.15 K. The accuracy of the temperature measurements was 0.1 K. The setup used to measure the gas solubility in a solvent was illustrated in our previous work [9]. The apparatus consisted of a gas reservoir, an equilibrium cell, a magnetic stirrer and two pressure transducers. Briefly, the gas solubility was measured as follows: first, the accurate amount of solvent was loaded in the equilibrium cell; At the next step, the gas was introduced into the gas reservoir and the pressure was recorded with the pressure transducers; As the third step, the gas was introduced from the gas reservoir into the equilibrium cell and dissolved in the solvent. The pressures of the gas reservoir and the equilibrium cell were recorded. The moles of gas dissolved in the liquid phase were determined from the pressure change in the gas reservoir, the equilibrium pressure and the volume of the equilibrium cell. 2.3 Experimental results 2.3.1 Density and viscosity The density and viscosity of the aqueous [Amim][HCOO] were measured at temperatures ranging from 293.15 to 333.15 K, at atmospheric pressure. The results are listed in Table 1. With increasing water concentration, the density and viscosity of aqueous [Amim][HCOO] decreased. Comparing the aqueous solutions with the dry [Amim][HCOO], the density of aqueous [Amim][HCOO] decreased by 0.65% and the viscosity decreased by 76.4% at 293.15 K when the mass fraction of water was 0.10. Therefore, a small amount of water decreased significantly the viscosity of [Amim][HCOO]. With increasing temperature, the density of aqueous [Amim][HCOO] decreased linearly, while the viscosity showed a polynomial decrease. For example, when the temperature increased from 293.15 to 313.15 K, the density of (0.9 [Amim][HCOO] + 0.1 H2O, mass fraction) decreased byPDF Image | CO2 Separation with Ionic Liquids
