Excess molar volumes, and excess molar enthalpies of (N-methyl-2-pyrrolidinone+ an ether ) at the temperature 298.15 K

Excess volumes and excess enthalpies of N-methyl-2-pyrrolidone with branched alcohols

“…Moreover, several researchers explicitly elucidated in the literature for the excess enthalpies (H E ) of binary mixtures containing NMP + aromatic hydrocarbons [20,24], +hydrocarbon [21,25,26], or +N-methylcaprolactam [27], +chloroethanes and chloroethenes [28], +an ether [23]. However, no effort appears to have been made to collect the V E and H E for the mixtures of NMP with branched alkanols and there is no evidence for specific interactions between of NMP with branched alkanols.…”

“…In other words, excess molar volumes (V E ) of binary mixtures containing NMP + aromatic hydrocarbons [19,20], +hydrocar-bon [16,21], +chloroethanes and chloroethenes [22], +an ether [23] have been appeared in the literature. Moreover, several researchers explicitly elucidated in the literature for the excess enthalpies (H E ) of binary mixtures containing NMP + aromatic hydrocarbons [20,24], +hydrocarbon [21,25,26], or +N-methylcaprolactam [27], +chloroethanes and chloroethenes [28], +an ether [23].…”

"Intermolecular Interactions in Aqueous Solution of Polyvinyl Alcohol "

“…Ultrasonic waves can propagate through matter and therefore they can be used for detecting the discontinuities present in a cast or forged materials 3 . The volumetric properties of binary liquid mixtures have been extensively studied [4][5][6][7] , as they can contribute to a clarification of the various intermolecular interactions between the different species existing in solution. Polyvinyl alcohol is interesting from several aspects.…”

Thermodynamics of binary mixtures of N-methyl-2-pyrrolidinone and ketone. Experimental results and modelling of the (solid+liquid) equilibrium and the (vapour+liquid) equilibrium. The modified UNIFAC (Do) model characterization

“…As a part of our systematic program of research on mixtures containing NMP with different organic solvents (alcohols, or ethers, or ketones, or chlorobenzenes), experimental data on (solid + liquid) equilibrium, SLE [4][5][6], excess molar enthalpies, H E m and excess molar volumes, V E m [7][8][9][10][11] have been previously reported. Mixtures of (NMP + 1-alkanol) [7,8,12,13] have been studied in the framework of the Extended Real Associated Solution, ERAS model [14], the modified UNIFAC (Do) model [13] and the DISQUAC model [13].…”

“…We are engaged in a systematic investigation of the extension and improvement of the modified UNIFAC parameterÕs matrix. To increase the temperature range covered by the parameters, H E m measurements, VLE measurements at high temperatures and measurements of SLE data of NMP [4][5][6][7][8][9][10][11][12][13] have been performed in our laboratory with the view to the extension and revision of the modified UNIFAC (DO) model parameters.…”
