ABSTRACT
The solubilities of 4,4-bis[[4-morpholino-6-(p-sulfonatoanilino)-1,3,5-triazin-2-yl]amino]stilbene-2,2 -disulphonate (FBA 210) in sodium chloride + water were measured by a synthetic method in the temperature range from (273.15 to 313.95) K. The solubility data are correlated with the modified Apelblat equation, and the parameters are estimated by the nonlinear least-squares regression method. Computation shows that the equation can predict the observed solubility behavior with an average deviation of about 2.1 %. The parameters A, B, and C are expressed as a function of the mass fraction (w) of sodium chloride in sodium chloride + water. The solubilities of FBA 210 in sodium chloride + water can be calculated by interpolation with acceptable precision for an industrial application.
