ABSTRACT

The refractive indices n of pure tetrahydrofuran (THF), benzene, toluene, o-xylene, m-xylene, p-xylene, mesitylene, and those of their binary mixtures with THF as a common component, over the entire composition range expressed by mole fraction x1 of THF, were measured at temperatures (288.15, 293.15, 298.15, 303.15, 308.15, 313.15, and 318.15) K. From the experimental data, the deviations in refractive index (An) have been calculated. It is observed that the extent of deviation in An for these mixtures follows the sequence: benzene greater than toluene greater than p-xylene greater than m-xylene greater than o-xylene greater than mesitylene.
