This work presents a study of solid–liquid equilibrium of sucrose in three different binary liquid mixtures, methanol–ethanol, methanol–water, and ethanol–water for the temperatures of 303 and 313 K covering the whole composition range of the binary liquid solution. The data are presented as a function of the dielectric constant of the binary liquid mixture taking into account the self-association of water and alcohol. From a dissolution phenomenon standpoint, it seems that the temperature is more important than the dielectric constant of the binary liquid solution for the solubility mechanism. For each temperature, it was observed that the sucrose solubility is directly proportional to the dielectric constant of the binary liquid mixture.

“…The two-parameter McAllister three-body (MAC3) and three-parameter McAllister four-body (MAC4) equations, on the other hand, were correlated with the kinematic viscosities, ν ; the latter being related to η and densities, ρ, as ν = η/ρ. All the experimental data of η and ν in use were collected from previous publications by different authors. − Moreover, the results of ρ and η correlations were also compared with the equations of simple polynomials and the Jouyban-Acree model of different degrees. The correlating abilities of each of the above models were tested by calculating the standard percentage deviation, σ%, between experimental and calculated values as Here, Y exp and Y cal refer to experimental and calculated ρ, η, or ν; n represents the number of data points and p is the number of coefficients taken.…”

The present study mainly reports the theoretical estimation of dynamic viscosities, η, and kinematic viscosities, v, for 150 binary liquid systems comprising different categories of organic compounds: alkanes, alcohols, aromatics, ketones, esters, and amines as well as some other typical organics containing O, N, and S atoms: acetonitrile, nitromethane, nitrobenzene, pyridine, 4-methylpyridine, dimethyl sulfoxide, and sulfolane. Computations were performed following two different approaches. The first methodology corresponded to correlative models of Grunberg-Nissan, Hind, Heric, Ausländer, McAllister three-body and four-body equations as well as the Jouyban-Acree model. Fitting capabilities of simple polynomial equations and that of the Jouyban-Acree model for density and viscosity correlations were also tested for different degrees of polynomials. Accuracies of different models were analyzed by comparing values of σ% as well as overall σ% for different categories of binary systems investigated. Correlative models with a higher number of parameters can yield satisfactory results, the quality of correlations being dependent on the symmetry of model equations, molecular interactions, and the number of available data points also. On the other hand, the second methodology belongs to a predictive model: the UNIFAC-VISCO. Applicability of existing αnm parameters in predicting dynamic viscosities of the selected binary mixtures is tested by calculating the respective AAD%. The results for AAD% and OAAD% values suggest that the UNIFAC-VISCO model can yield very good results in predicting both the dynamic and kinematic viscosities of liquid mixtures. Finally, 34 pairs of new group–group interaction parameters, αnm, of the UNIFAC-VISCO model were determined with various amines, acetonitrile, nitromethane, nitrobenzene, pyridine, dimethyl sulfoxide, sulfolane, etc. as one of the components. The availability of these new group interaction parameters would contribute further in extending the range of applicability of the conventional UNIFAC-VISCO model, even to a wider range of multicomponent liquid systems.

The knowledge of ion-solvent interaction by the help of volumetric and other fundamental properties has great importance and data generated from these experiments used for industrial applications. The experimental data of densities at 313.15K and 323.15K have been obtained for potassium dichromate (K 2 Cr 2 O 7 ) in 10% sucrose-aqueous solution measured as a function of their concentration. Experimental data of density evaluates the values of apparent molar volume, limiting apparent molar volume, experimental slope, molar volume and excess molar volume. The results were interpreted in the light of ion-ion and ion-solvent interactions and of structural effects of the solutes in solutions. These data give valuable information about interaction of compounds with carbohydrate which can be used for designing industrial and pharmaceutical applications.
