The excess molar volumes of twenty two binary mixtures containing various groups of organic compounds: alcohols (ethanol, 1-propanol, 1,2-propanediol, 1,3-propanediol and glycerol), ketone (acetone), ester (butyl lactate), lactam (N-methyl-2-pyrrolidone), PEGs (PEG 200, PEG 400) and aromatics (benzene, toluene and pyridine) were predicted from the refractive index data, using three types of equations coupled with several mixing rules for refractive index calculations: the Lorentz-Lorenz, Dale-Gladstone, Eykman, Arago-Biot, Newton, and Oster. The obtained results were analysed in terms of the applied equation and mixing rule and the nature of interactions between the mixtures? components.

AbstractIn this work, the experimental densities and viscosities have been determined for (propylene carbonate+acetonitrile, or dimethyl carbonate, or diethyl carbonate) binary mixtures over the whole concentration range at temperatures (293.15–333.15 K) and the atmospheric pressure.

Molar Volumes

Excess molar volumes VEm at 298.15 K and atmospheric pressure were calculated over the entire composition range from densities measured with a vibrating-tube digital densimeter for the binary mixtures butyl acetate + methanol, + ethanol, + propan-1-ol, + butan-1-ol, + pentan-1- ol, + hexan-1-ol, + heptan-1-ol, + octan-1-ol, + nonan-1-ol and + decan-1-ol. The excess volumes are positive over the entire composition range for these mixtures except the system butyl acetate + methanol, for which all VEm values are negative. The excess volumes show a consistent trend towards more positive values as the length of the hydrocarbon chain of the alkanol increases. The results suggest the presence of specific interactions.

Excess molar volumes (VEm) and viscosities (η) for mixtures of triethylene glycol dimethyl ether + dichloromethane, + trichloromethane, and + tetrachloromethane have been determined at 298.15 K and atmospheric pressure over the whole concentration range. From the experimental results, deviations in viscosities (Δ ln η) have been calculated. These properties were fitted to the polynomial relations to obtain the coefficients and the standard deviations. The results have been analysed in terms of molecular interactions between components.Key words: experiments, data, excess volume, viscosity deviation, binary mixtures.
