ABSTRACT
The densities of binary mixtures of aniline with 1-propanol, 2-propanol, 2-methyl-1-propanol, and 2-methyl-2-propanol were measured over the entire composition range, along with the pure components, at temperatures of 293.15, 298.15, 303.15, 308.15, 313.15, and 318.15K and atmospheric pressure. Using the experimental data, the excess molar volumes, VE m, and the temperature coefficients of the excess molar volume, VE m/T for the binary mixtures were calculated. The variations of these parameters with composition and temperature of the mixtures have been discussed in terms of molecular interactions in these mixtures. The VE m values were found negative for all the mixtures at each temperature studied, indicating the presence of specific interactions between aniline and alkanol molecules. The extent of negative deviations in VE m values follows the order: 1-propanol less than 2-propanol less than 2- methyl-1-propanol less than2-methyl-2-propanol. It is observed that the VE m values depend upon the positions of hydroxyl and methyl groups in these alkanol molecules.
