Data for the partial molar volume at infinite dilution for several gas
eous solutes and H3BO3 in water have been correlated using a generaliz
ed Krichevskii parameter. The result is a simple function for <(upsilo
n)over bar>(infinity)(1) in terms of the water density and compressibi
lity for conditions from ambient to 125 K and 40 MPa. The accuracy is
much better with only two parameters than with a previous five-paramet
er model.
