Abstract

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 ΔsolH and ΔsolS for each system revealed that sulfamethoxydiazine being dissolved in each solvent was an entropy-driven process.
