“…The refractive index of 95-octane gasoline pseudo-binary mixtures with isopropanol has recently been studied in [32,33]. Four different mixing rules, described by four equations, namely, the Eykman (Equation ( 6)), Lorentz-Lorenz (Equation ( 7)), Newton (Equation ( 8)) and Gladstone-Dale (Equation ( 9)):…”

In this article, we present the possibility of using terahertz time-domain spectroscopy to detect trace, ppm-level (%wt.) concentrations of admixtures in 95-octane lead-free gasoline in straightforward time-of-flight (pulse-delay) measurements performed directly in the liquid. The method was tested on samples containing 75–0.0125% of isopropanol and 0.3–0.0250% of water. The detection limits for isopropanol and water content were determined to be 125 ppm and 250 ppm, respectively, approaching the limits of much more complicated and time-consuming methods (like spectroscopy of the vapor phase). The measured pulse delays were compared with theoretical calculations using the modified Gladstone-Dale mixing rule for the solutions. The comparison demonstrated good agreement for gasoline-alcohol mixtures and large discrepancies for gasoline-water mixtures, suggesting that gasoline-water mixtures cannot be considered idealized binary mixtures. Our results clearly show that the pulse time delay measurement by THz-TDS is a fast and sensitive method of gasoline contamination detection and, as such, can be easily integrated with industrial online real-time quality control applications.

“…The study of the physicochemical properties of pseudo-binary mixtures represents a relevant issue given the great number of applications in industry and research. − For instance, these properties are essential for the development of useful mathematical models oriented to the optimization and control of large-scale industrial processes . From a scientific point of view, binary solvents are of special interest in structural biology, as cosolvents may exert a stabilizing or destabilizing influence on the native conformation of a protein .…”

Experimental and Theoretical Exploration of Volumetric Properties of Aminobutyric Acid and l-Valine in the Electrolytic Environment at T = 283.15 to 318.15 K and Pressure P = 0.1 MPa

In the present work, density (ρ) calculations, molecular dynamics (MD) simulations, and quantum chemical calculations of pseudo-binary mixtures of aminobutyric acid and L-valine in aqueous solutions of sodium thiosulfate (Na 2 S 2 O 3 ) at T = 283.15 to 318.15 K and atmospheric pressure (0.1 MPa) were performed. MD simulations reveal the formation of molecular aggregates induced by the preferential solvation in the mixture, due to the electrostatic interactions at the first layer of solvation between the charged groups of amino acids and the inorganic salt. The formation of these molecular aggregates is promoted by an increase in the salt concentration. Noncovalent interactions within the pseudo-binary mixtures were studied by the noncovalent interaction index (NCI) and IGM analysis, which well supported the experimental findings.

“…Viscosity is one of the important properties of fuels for diesel engine, affecting the pumping, spraying characteristics and combustion process. Continuing our studies on mixtures of fossil fuels with biofuels [13][14][15][16], the present paper reports viscosity data of pseudo-ternary biodiesel+diesel fuel+isopropanol system over the whole composition range and for temperatures between 293.15 K and 323.15 K. The ternary system is practically a pseudoternary mixture because both diesel fuel and biodiesel contain a mixture of the same class of chemical components, hydrocarbons in the case of diesel fuel and monoalkylesters of fatty acids for biodiesel. These fuels were characterised by physicochemical properties and average molar mass.…”
