ABSTRACT
The solubilities of acesulfame potassium in pure solvents and mixed solvents were measured using a synthetic method. The laser monitoring observation technique was used to determine the disappearance of the solid phase in a solid + liquid mixture. All data were measured at atmospheric pressure and temperatures ranging from (275.84 to 322.90) K. The effect of solvent composition and temperature on the solubility was discussed. The experimental data were correlated with an empirical equation.
