L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Volumetric Properties of Binary Mixtures of 1,2-Dichloroethane with Ethers from 278.15–333.15 K and at Atmospheric Pressure

“…These molecular interactions are essential for the development of appropriate thermodynamic models to design industrial processes. In line with previous experimental and theoretical works − on DCE with ether, this study presents the experimental densities of three mixtures, DCE + MTBE, DCE + DIPE, and DCE + DEE, at T = 278.15 to 333.15 K. In this work, we start by a presentation of the theory considered to correlate the experimental data. Then, the experimental apparatus is described.…”

Volumetric Properties of Furan and 2-5-Dimethylfuran in Different Industrial Solvents at Temperatures from 278 to 343 K

“…The PFP model was proposed to study excess thermodynamic properties of polar mixtures. − Using the same idea, some scientists used the Flory model to predict the excess volume, whereas others used the PFP theory. − The equation of state used in the PFP model was derived for pure compounds and mixtures as shown in eq . where T *, P *, and v * are the parameters obtained from the thermodynamic data of pure components.…”

Thermophysical, Acoustic, and Refractive Properties of Pure and Binary Mixtures Composed of Imidazolium-Based Ionic Liquids and PEG 600

“…It is considered that all the sites of the segments interact with the neighboring sites as per this theory. Hydrogen boding interaction and strong electrostatic interactions are excluded as per the PFP theory. , PFP theory divides V m E into (i) interactional contribution, V m E ( int ) (ii) free volume contribution, V m E ( fv ), and (iii) P* contribution, V m E ( P *). here x i , p i * , V i * , ∼ V i , θ 2 , and Ψ i are the mole fraction, characteristic pressure, molar volume, reduced volume, segment fraction, and contact energy fraction for the pure components, respectively. The relevant relations used in the current theory and various parameters involved have been calculated several times. − Flory’s interaction parameters used in the current calculation for the pure components are reported in Table .…”

“…Hydrogen boding interaction and strong electrostatic interactions are excluded as per the PFP theory. 79,80 PFP theory divides V m E into (i) interactional contribution, V m E (int) (ii) free volume contribution, V m E (fv), and (iii) P* contribution, V m E (P*).…”
