: The prediction of infinite dilution volatilities (Henry's law constants) of aroma compounds is examined. At 25 °C, the Bond Contribution model is recommended. At other temperatures where the Bond Contribution model cannot be used, the Kow-UNIFAC group contribution model, coupled with either experimental or predicted by the Antoine-Grain model vapor pressure values, provides estimates only of the volatilities with errors in the range of 20% to 40%. Finally, the effect of a cosolvent (ethanol) on the infinite dilution volatilities of some aroma compounds is examined.
