The excess molar volumes and enthalpies of (N-methyl-2-pyrrolidinone+ an alcohol) atT= 298.15 K and the application of the ERAS theory

1H NMR spectroscopic and thermodynamic studies of hydrogen bonding in liquid n-butanol + cyclohexane, tert-butanol + cyclohexane, and n-butanol + pyridine mixtures

“…16 It has been applied to thermodynamic excess properties of various alcohol + hydrocarbon mixtures [17][18][19][20][21] and has also been extended to a large variety of mixtures containing self associating molecules and a second component such as amines or ethers where a cross association between the two components has to be accounted for. [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] The application of the ERAS model for describing 1 H NMR chemical shifts of the hydroxyl proton d OH of alcohol mixed with hydrocarbons or cross associating substances such as pyridine or amines has not yet been developed and is presented here for the first time.…”

Density and Viscosity of 2-Butanol + (1-Propanol, 2-Propanol, or 3-Amino-1-propanol) Mixtures at Temperatures of (293.15 to 323.15) K: Application of the ERAS Model

“…Φ A and Φ B are the volume fractions of components A and B in the mixture, respectively. The other needed association parameters ( K i , Δ h i * , and Δν i * ) were taken from refs , , , , , and as listed in Table .…”

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].…”

The excess molar volumes, V E m have been measured at T = 298.15 K and atmospheric pressure for nine binary mixtures of (N-methyl-2-pyrrolidinone + 2-propanone, or N-methyl-2-pyrrolidinone + 2-butanone, or N-methyl-2-pyrrolidinone + 2-pentanone, or N-methyl-2-pyrrolidinone + 3-pentanone, or N-methyl-2-pyrrolidinone + cyclopentanone, or N-methyl-2-pyrrolidinone + 2-hexanone, or N-methyl-2-pyrrolidinone + 4-methyl-2-pentanone, or N-methyl-2-pyrrolidinone + 4-heptanone, or N-methyl-2-pyrrolidinone + 5-nonanone) and excess molar enthalpies, H E m for two mixtures (NMP + 4-heptanone, or NMP + 5-nonanone) [11].…”

“…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.…”
