where T is absolute temperature in Kelvin; Am and Bm are constants
obtained by regressing solubility data which are given in table 3;
m = 2, 3, and 4 represent for water, propanol, and ethylene glycol,
respectively.
In the solvent mixtures, the solubility product of NTSNa in
(m1 + m2) binary solvent mixtures is calculated by
