Prediction of Infinite Dilution Volatilities of Aroma Compounds in Water

摘要

The prediction of infinite dilution volatilities (Henry's law constants) of aroma compounds is exam- ined. At 25 deg. 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 20/100 to 40/100.
