TL;DR: In this paper, the solubility of imatinib mesylate (as a paradigm for cancer chemotherapy) in SC-CO2 was determined using three different groups of methods including (1) three equations of state (EoSs), namely Soave-Redlich-Kwong (SRK), Pazuki et al., and Haghtalab et al. (HKM) with vdW2 mixing rule, and (2) six density-based semi-empirical models were applied to correlate the test data of IMC.
Abstract: For the first time, solubility of imatinib mesylate (as a paradigm for cancer chemotherapy) in SC-CO2 was determined. Experiments were performed at operating temperatures and pressures of 308.2–338.2 K and 120–270 bar, respectively. Two different groups of methods including (1) three equations of state (EoSs), namely Soave–Redlich–Kwong (SRK), Pazuki et al. (PAZ), and Haghtalab et al. (HKM) with vdW2 mixing rule and (2) six density-based semi-empirical models were applied to correlate the solubility data of imatinib mesylate. The calculated results indicated the superiority of HKM EoS over other models. Then, a new, comprehensive empirical model with six adjustable parameters was proposed and compared with existing empirical models. The superiority of this model was confirmed by experimental solubility data of imatinib mesylate and 25 solubility datasets published in the literature. The proposed model could correlate the experimental solubility of imatinib mesylate with satisfactory accuracy.
