Thermodynamics of the solubility of sulfamethoxydiazine in organic solvents in the range 293.15–323.15 K

Resumo

The solubilities of sulfamethoxydiazine in methanol, ethanol, 1-propanol, 2-propanol, acetone, and chloroform have been determined in the range 293.15–323.15 K by a static equilibrium method. The calculated results show that the correlation of the Apelblat equation for measured systems has less deviation than that of the λh equation. The positive Δ_solH and Δ_solS for each system revealed that sulfamethoxydiazine being dissolved in each solvent was an entropy-driven process.
