Experimental study and modelling using the ERAS-Model of the excess molar volume of acetonitrile–alkanol mixtures at different temperatures and atmospheric pressure

Application of the UNIFAC model for prediction of surface tension and thickness of the surface layer in the binary mixtures

“…The role of surface tension and hydrogen bonding in the observed patterns is very important. According to the literatures [31,32], acetonitrile is a non-associating compound. A self-associated alcohol is mixed with acetonitrile, which can cross-associate strongly with the former.…”

Volumetric properties of binary mixtures of (water+organic solvents) at temperatures between T=288.15 K and T=303.15 K at p=0.1 MPa

“…The present work, which is a continuation of our study of volumetric properties of liquid binary mixtures [2][3][4][5][6][7][8], involves binary liquid mixtures of {water + formamide (FM), or + 1,4-dioxane, or + dimethylsulfoxide (DMSO), or + N,N-dimethylformamide (DMF), or + N,N-dimethylacetamide (DMA)}, as a function of composition, at temperatures between T = 288.15 K and T = 303.15 K at p = 0.1 MPa.…”

Volumetric Properties of Chloroalkanes + Amines Mixtures: Theoretical Analysis Using the ERAS-Model

“…For the remaining systems, V E m is negative over the entire composition range (Figs. 3,4,5,6,7,8,9). Spectroscopic evidence in the literature indicates the possibility of two types of interactions present in the system studied (1) hydrogen bonding between the C-H hydrogen of the chloroalkanes with the n-donor atom of amines [24][25][26][27][28] and (2) charge transfer complex between the π -electrons of chlorine atoms with the lone pair in amines [29][30][31][32][33][34][35][36].…”

“…Following up our thermodynamic study of binary mixtures [1][2][3][4][5], in this study excess molar volumes of {dichloromethane (DCM) or trichloromethane (TCM) + n-butylamine (n-BA), or +s-butylamine (s-BA), or +t-butylamine (t-BA), or +dieth-ylamine (DEA), or +triethylamine (TEA)} mixtures as a function of composition have been used to test the applicability of the extended real associated solution model (ERAS-Model) [6,7]. It combines the Kretschmer-Wiebe model of linear successive association [8] with Flory's equation of state [9].…”
