The solubility of menthol [C10H20O] in supercritical carbon dioxide wa
s measured by using a flow-type apparatus at 35-55-degrees-C and press
ures ranging from 6.7 to 11.6 MPa. The results were correlated with th
e density of pure solvent according to the Adachi-Lu equation. This ap
proach yielded deviations of 4.4%.
