Excess molar volumes of binary mixtures of acetonitrile and chloroalkanes at 298.15 K and atmospheric pressure with application of the ERAS-Model

Excess molar volumes and viscosity behaviour of binary mixtures of aniline/or N,N-dimethylaniline with imidazolium ionic liquids having triflate or bistriflamide anion

“…The outcome of the interplay between these interactions is strongly linked to the deviation from the ideal behaviour of such mixtures and, thus, to the related excess thermodynamic properties or deviation functions. The latter can be explained and interpreted on the bases of the existing interactions [83][84][85][86]. Considering partially negatively charged nitrogen and partially positive charged hydrogen atoms from the amine group, it is evident that aniline can be both hydrogen bond donor (HBD) and hydrogen bond acceptor (HBA) (see hydrogen bond acidity α (HBD ability) and hydrogen bond basicity β (HBA ability) parameters of aniline given in Table5).…”

Experimental (solid+liquid) or (liquid+liquid) phase equilibria of (amine+nitrile) binary mixtures

“…The calculated values of the equation parameters and corresponding root-mean-square deviations are presented in table 6. In binary systems the average deviations was r x = 0.0094.…”

“…On the other hand, mixtures of (amine + nitrile) are also known from the literature to show much weaker interactions, than those observed in (amine + alkan-1-ol). The measurements of molar excess volumes, V E m [6][7][8] for (diethylamine, or s-butylamine + acetonitrile) and molar excess enthalpies, H E m [9] for (aniline, or n-butylamine + acetonitrile) systems were presented previously. The (solid + liquid) phase diagram, (SLE) for (decylamine + acetonitrile) system was also presented [10].…”

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].…”
