Notes
12) |
Value at T = 293 K. |
100) |
Calculated based on the method by Meylan and Howard (1991). |
187) |
Estimation based on the quotient between vapor pressure and water solubility, extracted from HENRYWIN. |
569) |
Value given here as quoted by Goodarzi et al. (2010). |
570) |
Goodarzi et al. (2010) compared several QSPR methods and found that the Levenberg-Marquardt algorithm with Bayesian regularization produces the best results. Values obtained with other methods can be found in their supplement. |
573) |
Value from the test set. |
