“…Consequently, pulegone is subject to several regulations as flavouring agent by the European Parliament and limitations in its use as cosmetic ingredient [13]. Finally, 1-octen-3-ol (also known as -mushroom alcohol‖) is a volatile compound present in several plant species such as Lantana camara [15], Premna integrifolia [16], Epilobium parviflorum [17], in essential oils extracted with scCO 2 from rosemary [18] and lavender [19], etc. It is also used as a spoilage indicator in stored cereals because it is one of the most important flavor components produced by mushrooms [20].…”

In this work, the solubility of thymoquinone, R-(+)-pulegone and 1-octen-3-ol in supercritical CO 2 is determined in a range of conditions typical of supercritical fluid processes such as extraction, fractionation and impregnation. These compounds were selected based in their insecticidal activity which may enable to apply them as biopesticides. Solubility was measured using a semicontinuos method in the temperature range of 45-65°C and pressure of 8-12 MPa, at a CO 2 flowrate of 0.05-0.10 g/min, which was verified to be low enough to ensure saturation. Solubilities were predicted using the Group Contribution Equation of State (GC-EoS) and compared to the experimental results, with a good agreement. Consistency of the data was tested using the density-based Chrastil equation.
