摘要: Background: To overcome low solubility of naproxen (NAP), deep eutectic solvents (DESs) based on choline chloride (ChCl) with glycerol (G) and oxalic acid (OA) as green have been used up to 0.9 mole fraction DES at T = (298.15 313.15) K. Methods: DESs were prepared by combination the two components molar ratios: ChCl/glycerol (1:2) ChCl/oxalic (1:1). The NAP in aqueous solutions was measured different temperatures shake flask method. Results: these increased increasing weight DESs, especially ChCl/OA. data correlated e-NRTL, Wilson UNIQUAC models. Also, thermodynamic functions, Gibbs energy, enthalpy, entropy dissolution obtained. Conclusion: Oxalic exhibits higher than DES. models successfully correlate data. In addition, results show that, main contribution for is enthalpy.
