The solubility of aceclofenac in six pure solvents from (293.35 to 338.25) K was experimentally measured using a synthetic method. The experimental results indicate obviously that the solubility of aceclofenac in the selected solvents increases with elevated temperature. Furthermore, the experimental solubility data were fitted with modified Apelblat and Wilson models. The results show that the data calculated by the two models agree with the measured data with RMSD values of no more than 2.75 %.
