Densities, viscosities, refractive indices, and excess molar enthalpies ofmethyl tert-butyl ether plus components of pine resins and essential oils at 298.15 K

Densities, rho, viscosities, eta, refractive indices, n(D), and excess Mola r 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-methy l-4-(l-methylethyl)benzenel, + (S)-(-)-limonene [(-)-1-methyl-4-(1-methylet henyl)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 298.1 5 K and at atmospheric pressure using a digital density meter, a Schott mea suring system, an Abbe refractometer, and a flow microcalorimeter, respecti vely. 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 stan dard deviations. Results were also qualitatively discussed in terms of mole cular interactions.
