Solubility and metastable zone width measurement of 2,4-diaminobenzenesulfonic acid in(H2SO4+H2O)system
文献摘要：
The equilibrium solubility of 2,4-diaminobenzenesulfonic acid and super solubility as well as metastable zone width were measured in(H2SO4+H2O)system by the laser dynamic method at elevate temperature range from 298.15 K to 338.15 K.2,4-Diaminobenzenesulfonic acid solubility dependence on the temper-ature and solvent composition were correlated by the modified Apelblat equation,(CNIBS)/Redlich-Kister model and Jouyban-Acree model.The correlated results by three correlation models were in good accord with the experimental values according to relative average deviations(RD),root-mean-square deviations(RMSD),and correlation coefficients(R2).The metastable zone width increased with temperature and sul-furic acid content.The dissolution enthalpy,dissolution entropy and the Gibbs energy were calculated from the experimental values,which indicated that dissolution process of the 2,4-diaminobenzenesulfonic acid was endothermic.The solubility and calculation models of 2,4-diaminobenzenesulfonic acid in(sulfuric acid+water)system could provide the basic data to the crys-tallization and purifying of the 2,4-diaminobenzenesulfonic acid.
