In this study, the solubility parameters of the local anesthetic drug bupivacaine hydrochloride (BH) were measured. The solvents used for measurement were methanol, ethanol, acetic acid, and water. The solubility was also determined in binary solvent systems of methanol + water and ethanol + water. The experimental results showed a dependence of solubility on temperature and were successfully correlated with theoretical models.
In the present work, the solubility parameters of the local anesthetic drug bupivacaine hydrochloride (BH) were measured. The pure solvents under study were methanol, ethanol, acetic acid, and water. Two binary solvent systems, namely, methanol + water and ethanol + water, were also used to determine the solubility. The experimental solubility of the BH was obtained by the gravimetric method over a series of temperatures (293.15-333.15 K) in different mono and binary solvents under atmospheric pressure. Experimental results reveal the dependence of solubility on temperature. The experimental mole fraction solubility was further correlated with theoretical models such as the Apelblat, lambda h, Van't Hoff, modified Jouyban-Acree, and CNIBS/R-K models. The small values of RAD and RMSD indicated that the data are in good agreement with experimental data. The data of solubility can be applied in the fields of production, purification, crystallization, and separation of BH.
