Densities, rho, viscosities, eta, refractive indices, n(D), and excess Molar enthalpies, H-m(E), of binary mixtures containing methyl tert-butyl ether (MTBE) + alpha -pinene (2,6,6-trimethylbicyclo[3.1.1]hept-2-ene), + beta -pinene (6,6-dimethyl-2-methylenebicyclo[3.1.1]heptane), + p-cymene (1-methyl-4-(l-methylethyl)benzenel, + (S)-(-)-limonene [(-)-1-methyl-4-(1-methylethenyl)cyclohexenel, + 1,8-cineole(1,3,3-trimethyl-2-oxabicyclo[2.2.2]octane), and + linalool (3,7-dimethyl-1,6-octadien-3-ol) were determined at 298.15 K and at atmospheric pressure using a digital density meter, a Schott measuring system, an Abbe refractometer, and a flow microcalorimeter, respectively. The excess molar volumes, V-m(E) the deviations in viscosities, Delta eta, and in refractive indices, DeltaR, and the excess molar enthalpies, H-m(E), were calculated from experimental measurements. Results were fitted to the Redlich-Kister equation to obtain the adjustable parameters and standard deviations. Results were also qualitatively discussed in terms of molecular interactions.
