Further computations on physico-chemical properties of binary mixtures of p-cymene with a-pinene, limonene and citral

The density, molar volume, refractive index, dynamic viscosity, speed of sound and isentropic compressibility data of binary mixtures of p-cymene with alpha-pinene, limonene and citral at 288.15-323.15 K and 0.1 MPa were represented using a single mathematical model, i.e. Jouyban-Acree model. Accuracy of the model was compared with those of the presented models in a recent paper by Ilic-Pajic et al. where more accurate results were obtained using the proposed model. The main advantages of the proposed model are its single mathematical form for all physico-chemical properties (PCPs), simple computations, and representing both mixture composition and temperature effects. It has also been shown that one may measure a minimum number of PCP data, train the model and then predict the PCP data at any liquid mixture composition and temperature of interest using an interpolation technique. In addition, the capability of the proposed model to represent the PCPs of ternary and higher-order liquid mixtures has been shown employing the experimental data collected from the literature.(c) 2021 Elsevier B.V.
