“…These fits show linear behaviors for density and refractive index with temperature, while for viscosity, this dependence is exponential. To obtain the respective dependencies on composition and temperature, we adopt the same procedure that was previously described. ,,, The appropriate number of significant digits was selected taking into account the experimental errors for density, refractive index, viscosity, and temperature reported above.…”

Density, viscosity, and refractive index measurements for pure formamide and water at T ) (293.15, 303.15, 313.15, and 323.15) K as well as for the binary system {x 1 formamide + (1-x 1 ) water} at the same temperatures were made over the whole concentration range. Isobaric (vapor + liquid) equilibrium at P ) 2.5 kPa for this binary system was also measured. The experimental results of density, viscosity, and refractive index were fitted to empirical equations, which makes it possible to calculate these properties over the whole studied concentration and temperature ranges. Calculated values are in good agreement with the experimental results. Data of the binary mixture were further used to calculate the excess molar volume, viscosity and refractive index deviations, and the activity coefficients. The excess or deviation properties were fitted to the Redlich-Kister polynomial relation to obtain their coefficients and standard deviations. This binary system shows negative deviations from the ideal behavior and no azeotrope.

Densities of N, N′-1,2-ethyl-bis(salicyladimine) Schiff base (salen) in dimethylsulfoxide (DMSO), N,Ndimethylformamide (DMF), N,N-dimethylacetamide (DMA), dichloromethane (CH 2 Cl 2 ), and chloroform (CHCl 3 ) binary mixtures have been measured in dilute concentration regions of salen at T ) (283.15 to 318.15) K under ambient pressure. Apparent molar volumes, V φ , and standard partial molar volumes, V φ 0 , have been calculated from the measured densities. The V φ 0 values in DMSO have larger values corresponding to the high polarity of this solvent. The results show that their values would be increased slightly with an increase in temperature. The partial molar expansivities, E φ 0 , and the isobaric thermal expansion coefficients, R*, have been calculated from the temperature dependence of V φ 0 values. The Hepler's constant values, (∂ 2 V φ 0 /∂T 2 ) p , were found to be positive or very small and negative which indicate that salen Schiff base is predominately a structure maker in all organic solvents studied.

“…They were taken from our previous paper . Comparison of measured and literature − data for densities and viscosities of MIBK is shown in Table . The observed differences between two sets of data (experimental and literature) are due to the apparatus calibration procedure, different sources of materials, different sorts and amounts of impurities, and different techniques of measurements (e.g., SVM 3000 viscometer, Anton Paar DMA 4500, Canon-Ubbelohde viscometers, and so forth).…”

In the present study, to identify the governing intermolecular interactions in the binary mixtures of methyl isobutyl ketone (MIBK) and 1-alkanols (1-hexanol up to 1-decanol), experimental values of density and viscosity at temperatures (293.15 to 323.15 K) were reported. Excess molar volumes (V m E) and viscosity deviations (Δη) for mentioned binary mixtures were calculated and correlated by the Redlich–Kister polynomial expansions. It was found that increasing the alkyl chain of alcohol boosts the strength of intermolecular forces. Also, to obtain more information about the governing forces in the binary mixtures, values of Hansen solubility parameter distance between two molecules, R a, were calculated, and based on the obtained results, the tendency of alcohol to dissolve in the MIBK media was discussed.
