“…In this work, we have measured experimental densities and viscosities for binary mixtures of 1-pentanol + 2-pentanol, 1-pentanol + 2-methyl-1-butanol, and 2-pentanol + 2-methyl-1-butanol from (288.15 to 328.15) K at 0.1 MPa over the entire composition range. Density and viscosity measurements of pure pentanol isomers are compared with values reported in the literature, ,− as shown in Table . The average absolute percentage deviations (AAPD) between our density measurements and literature values are (0.035, 0.036, and 0.103) % for 1-pentanol, 2-pentanol, and 2-methy1-butanol, respectively.…”

Densities and Viscosities for Binary Liquid Mixtures of Pentanol Isomers from (288.15 to 328.15) K at 0.1 MPa

This paper presents densities and viscosities of binary mixtures of 1pentanol + 2-pentanol, 1-pentanol + 2-methyl-1-butanol, and 2-pentanol + 2-methyl-1-butanol from (288.15 to 328.15) K over the entire concentration range at atmospheric pressure. Experimental densities and viscosities are measured using a vibrating tube densimeter and a glass capillary viscometer, respectively. The relative standard uncertainties estimated in the density and viscosity were 4.8 × 10 −4 and 0.01, respectively. Densities and viscosities of the binary mixtures are compared with the limits established by the diesel fuel standard (EN 590). The binary mixtures of 1pentanol + 2-methyl-1-butanol, and 2-pentanol + 2-methyl-1-butanol could be considered as alternative substitutes for diesel fuel. Excess molar volume values suggest that these mixtures behave as ideal solutions. Viscosity deviations are negative for all of the mixtures investigated in this study. The Redlich−Kister equation is used to represent the behavior of the excess molar volumes and viscosity deviations as a function of the composition. The Nava-Ri ́os and McAllister equations correlate the kinematic viscosity values with an average absolute percentage deviation of 0.139% and 0.203%, respectively.

“…Strong and weak interactions between unlike molecules in mixtures lead to deviations from ideality. Deviations from ideality in binary liquid mixtures are usually associated with synergism and are attributed to differences in the chemistry and molecular architecture of the mixing solvents [8][9][10][11][12][13][14] as well as the experimental conditions such as temperature and the mixing ratios of the binary liquids.…”

Densities of binary mixtures of 2-methoxyethanol (2-MeO-EtOH) and 2-ethoxyethanol (2-EtO-EtOH) with hexylamine (HLA), diethylamine (DEA), triethylamine (TEA), tert-butylamine (TBA), aniline (ANL), and benzylamine (BLA) have been determined at varying compositions of the alkoxyalkanols at 298.15 K. The excess molar volumes, VE, of the binary mixtures were calculated from the experimental density data of the mixtures and the component single solvents. The calculated excess molar volumes were fitted into the Redlich-Kister polynomial to obtain the fitting coefficients and standard deviations. The excess molar volumes of the binary mixtures of all the solvent systems investigated were negative over the entire range of the solvents composition. The negative values were attributed to stronger hydrogen bond formations between the unlike molecules of mixtures than those between the like molecules of the pure components. The magnitude of the excess molar volumes of the binary mixtures of 2-methoxyethanol and the aliphatic amines were in the order TBA > TEA > DEA > HEA. For the two aromatic amines, the magnitudes were in the order BLA > ANL. For binary mixtures of the amines and 2-ethoxyethanol, the magnitudes were in the order DEA > TEA > TBA > HEA at compositions where the mole fraction of 2-EtO-EtOH was ≤0.5 and TBA > TEA > DEA > HEA above 0.5 mole fraction of 2-EtO-EtOH.

“…All the calculated quantities are reported along with an estimate of the statistical error, calculated as the standard deviation over five independent simulation repeats (for D and ε, see Sections II.4.5 and II.4.7), or using block-averaging 1 over a single simulation (for all other quantities).For each property, experimental data was usually only available for a subset of the 57 molecules. The corresponding experimental values are listed inTable B.3 based onRefs [126][127][128][129][130][131][132][133][134][135][136][137][138][139][140][141][142][143][144][174][175][176][177][178][179][180][181][182][183][184][185][186]. .The classical[187][188][189][190] (i.e.…”

This article reports on the calibration and validation of a new GROMOS-compatible parameter set 2016H66 for small organic molecules in the condensed phase. The calibration is based on 62 organic molecules spanning the chemical functions alcohol, ether, aldehyde, ketone, carboxylic acid, ester, amine, amide, thiol, sulfide, and disulfide, as well as aromatic compounds and nucleic-acid bases. For 57 organic compounds, the calibration targets are the experimental pure-liquid density ρliq and the vaporization enthalpy ΔHvap, as well as the hydration free energy ΔGwat and the solvation free energy ΔGche in cyclohexane, at atmospheric pressure and at (or close to) room temperature. The final root-mean-square deviations (RMSD) for these four quantities over the set of compounds are 32.4 kg m(-3), 3.5 kJ mol(-1), 4.1 kJ mol(-1), and 2.1 kJ mol(-1), respectively, and the corresponding average deviations (AVED) are 1.0 kg m(-3), 0.2 kJ mol(-1), 2.6 kJ mol(-1), and 1.0 kJ mol(-1), respectively. For the five nucleic-acid bases, the parametrization is performed by transferring the final 2016H66 parameters from analogous organic compounds followed by a slight readjustment of the charges to reproduce the experimental water-to-chloroform transfer free energies ΔGtrn. The final RMSD for this quantity over the five bases is 1.7 kJ mol(-1), and the corresponding AVED is 0.8 kJ mol(-1). As an initial validation of the 2016H66 set, seven additional thermodynamic, transport, and dielectric properties are calculated for the 57 organic compounds in the liquid phase. The agreement with experiment in terms of these additional properties is found to be reasonable, with significant deviations typically affecting either a specific chemical function or a specific molecule. This suggests that in most cases, a classical force-field description along with a careful parametrization against ρliq, ΔHvap, ΔGwat, and ΔGche results in a model that appropriately describes the liquid in terms of a wide spectrum of its physical properties.
