We list infinite dilution activity coefficients, γ∞, in water for 81 compounds from 273.15 to 373.15 K, and we use our linear free energy relationship to obtain equations for log γ∞ at 5 K intervals between 273.15 and 373.15 K. These equations, together with Abraham descriptors can then be used to calculate or predict the temperature variation of activity coefficient in water with an estimated error...
We have assembled infinite dilution activity coefficients in water at 298 K for 661 varied compounds. For 655 of these compounds we were able to construct a multiple linear regression equation using Abraham descriptors with a standard deviation of 0.29 log units in log γ∞. Unlike methods such as ASOG or UNIFAC, our equation does not rely on functional groups, and so we can predict further values of...
