“…Such differences between the experimental and the theoretical value have already been observed in literature. 245,246 As the exponent μ is almost the same for these two models, it cannot be used for a clear differentiation between the theoretical values. As can be seen in Figure IV-8, the lower curve is not linear over the whole range, and such behavior has also been described in literature before.…”

“…The corresponding percolation threshold volume fractions f P were calculated from the inflection point of the curves log(k) ¼ f(f), 38,44 log(k) was fitted to a fourth order polynomial in f and the second derivative was set equal to zero. The resulting temperature dependent percolation threshold volume fractions, f P , are summarized in Table 1.…”

Surfactant-Free Microemulsion Based on CO₂-Induced Ionic Liquids

A novel surfactant-free microemulsion (SFME) based on CO2-induced ionic liquids (ILs) was prepared. Among them, dipropylamine (DPA) was directly reacted with CO2 to form the ILs that were composed of the ammonium salts and the ammonium carbamate salts, which was confirmed by 13C NMR, Fourier transform infrared, electrical conductivity, and pH. In addition, the purity of ILs was determined by 1H NMR. We used water as a polar phase, ILs as an amphi-solvent, and 1-dodecanol as a nonpolar phase to prepare SFME. The multiphase zone and the single-phase zone of the SFME were obtained from the ternary-phase diagram. Then, the microstructure of the studied SFME was determined to be the O/W type by the staining method. The demulsification process of SFME was explored by means of conductivity, pH, dynamic light scattering, and gas chromatography. Under the introduction of N2, CO2 could be removed, and the ILs could be reversibly restored to DPA, resulting in a change in polarity, which caused most of DPA to transfer into the oil phase, eventually leading to demulsification.
