CLARA, R.A.; GOMEZ MARIGLIANO, A.C.  y  SOLIMO, H.N.. Physicochemical properties and vapor-liquid equilibrium data for steam-distilled lemon essential oil. Lat. Am. appl. res. [online]. 2010, vol.40, n.1, pp.61-66. ISSN 0327-0793.

Density and refractive index for steam-distilled lemon essential oil were obtained at several temperatures and vapor pressure measurements over the pressure and temperature ranges of P= (2.5 to 80.0) kPa and T = (342.57 to 440.39) K, respectively. Dependence with temperature for these experimental results were fitted to empirical polynomial relations, in order to obtain their coefficients and standard deviations. Calculated values are in good agreement with the experimental ones. The molar enthalpy of vaporization for steam-distilled lemon essential oil was calculated plotting the logarithm of the vapor pressure against the reciprocal temperature. Vapor-liquid equilibrium data of some key components were also obtained over the pressure and temperature ranges of P = (10.0 to 80.0) kPa and T = (374.46 to 440.39) K, respectively. Compositions of both equilibrium phases were determined for these key components by gas chromatography (GC). The essential oil components were characterized by their GC-retention times and the results are compared with gas chromatogram (GC/ MSD) data previously reported in the literature.
