Density, excess molar volumes and refractive indices of β-pinene with o, m, p-xylene and toluene at 303.15, 308.15 and 313.15 K

Abstract

Densities (ρ), excess molar volumes (VE ), refractive indices (nD ) and deviation in refractive (ΔnD ) indices on mixing for β-pinene with o-xylene, m-xylene, p-xylene and toluene have been determined at T = 303.15, 308.15 and 313.15 K. The excess molar volume and deviation in refractive index have been fitted to Redlich–Kister polynomials. In addition, deviations in refractive indices were compared with the predictions of several mixing rules. Results obtained have been discussed in terms of intermolecular interactions.
