Densities, viscosities, and excess molar enthalpies of binary mixtures containing essential oils at (298.15 and 313.15) K. The (S)-(-)-limonene plus cineole, (S)-(-)-limonene plus linalool, and cineole plus linalool systems

Densities, rho, viscosities, eta, and excess molar enthalpies, H-m(E), of b inary mixtures containing (S)-(-)limonene [(-)-1-methyl-4-(1-methylethenyl) cyclohexene] + 1,8-cineole(1,3,3-trimethyl-2-oxabicyclo [2,2,2]octane), (S) -(-)-limonene + linalool (3,7-dimethyl-1,6-octadien-3-ol), and cineole + li nalool were determined at (298.15 and 313.15)K and at atmospheric pressure using a digital density meter, a Schott measuring system, and a flow microc alorimeter, respectively. The excess molar volumes, V-m(E), the viscosity d eviations, Delta eta, and the H-m(E)'s were calculated from experimental me asurements. Results were fitted to the Redlich-Kister polynomial to obtain the adjustable parameters and standard deviations. Results were also qualit atively explained in terms of molecular interactions.
