Measurements of νE for binary mixtures of CmH2m+1CO2CH3 (m = 1,2,3) + CnH2n+1(OH) (n = 2,3,4,5) are reported. The results have been determined by using the densities obtained in a vibrating tube densimeter at 298.15 K, they are positive for all these systems. The data have also been compared with available literature values with a discussion on these mixtures. Keywords: excess molar mixtures, methyl alkanoates, normal alkanols.

The excess molar volumes, [Formula: see text], of 2-hexanone (MBK) with n-hexane, n-heptane, n-octane, n-nonane, n-decane, n-undecane, n-dodecane, and n-tridecane have been obtained at 298.15 K from densities measured with a vibrating tube densimeter. The [Formula: see text] are positive over the entire composition range in all mixtures, with the exception of the MBK + n-hexane system, where an inversion of the sign of [Formula: see text] is observed. In other systems, [Formula: see text] increases with increasing size of the alkyl group in n-alkane.

Densities of binary mixtures of 1-propanol, or 2-butanol, or 1-pentanol + cyclohexylamine were measured at temperatures from 288.15 to 313.15 K and atmospheric pressure, while the densities for the system 2-methyl-2-propanol + cyclohexylamine were measured at temperatures from 303.15 to 323.15 K and atmospheric pressure. All measurements were performed using an Anton Paar DMA 5000 digital vibrating-tube densimeter. From the experimental densities, the excess molar volumes, VE, were calculated.

Densities, refractive indices and viscosities of the binary mixtures of dimethyl phthalate (or dimethyl adipate) + tetrahydrofuran have been measured at eight temperatures (288.15 to 323.15 K) and atmospheric pressure. All measurements were performed using an Anton Paar DMA 5000 digital vibrating-tube densimeter, Anton Paar RXA 156 refractometer and Anton Paar SVM 3000/G2 digital Stabinger viscometer, respectively. From the experimental densities, refractive indices and viscosities, the excess molar volumes, VE, deviations of refractive indices, DnD, and viscosity deviations, Dh, were calculated.

Excess molar volumes in the benzene-tert-amyl methyl ether and cyclohexane-tert-amyl methyl ether systems were measured by a vibrating-tube densimeter at 298.15 K and compared with the data for the methanol-tert-amyl methyl ether system determined previously. Besides, the refractive indices in both the systems were measured at the same temperature.

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.
