5.5.4 Constants for binary mixtures
R.N. Maddox
This section supplies the constants necessary for prediction of nonideal behavior using the Analytical Solution Of Groups (Table 1a—Table 1k). UNIFAC (Table 2a and Table 2b) and Parameters From Group Contributions (Table 3). Methods discussed in Section 504B.
