MARTINEZ-REINA, Marlon D.  and  AMADO-GONZALEZ, Eliseo. Refraction indexes and density for binary mixtures of heptane with cyclohexane, benzene and toluene at 293.15, 298.15, 303.15 K. Orinoquia [online]. 2012, vol.16, n.1, pp.110-120. ISSN 0121-3709.

Density and refraction indexes forbinary mixtures of cyclohexane, benzene and toluene with heptane (293.15, 298.15,303.15 and 308.15 K) were measured. Excess molar volume and refraction indexchange (δηD) werecalculated from experimental data and adjusted with a fourth-orderRedlich-Kister polynomial equation.

Keywords : refractionindex change; excessmolar volume; Redlich-Kisterequation; binarymixture; hydrocarbon.
