Significance of Theoretical Decomposition Enthalpies for Predicting Thermal Hazards

Table 1

Comparison of presently available predictive methods. The second column indicates which kind of measurements (SC and/or PH) are used to assess the predictive value of the method. In the third column, y/n indicates whether (y) or not (n) PH data for ortho compounds are included in the test set. In the last column, stands for the empirical parameter of present models; that is, it is equal to either when (2) is used or when using (4). and values are in kJ/mol.
