VOLUMETRIC AND DIELECTRIC-PROPERTIES OF VITAMIN-E IN BENZENE AND CARBON-TETRACHLORIDE SOLUTIONS

The densities, refractive indices and electric permittivities at 2MHz of benzene and carbon tetrachloride solutions of vitamin E were measur ed at 298 K in the concentration range up to 0.70 mol kg(-1) for benze ne solutions and 0.39 mol kg(-1) for carbon tetrachloride solutions. T he apparent molal volume of the solute, the molal refraction and molal polarization of the solutions, as well as the partial molal refractio n and partial molal polarization of the solute were calculated. In add ition, the dipole moment of the vitamin E molecule at infinite dilutio n and the apparent dipole moment were calculated, and the solvent effe ct on the dipole moment discussed.
