ملخص

Application of deep eutectic solvents (DES) in industrial chemical processes has been improved during the last decades. In this work, vapor pressures of 13 classes of DESs (DES 1-13) based on 5 salts and 7 hydrogen bond donors with various combinations of molar ratio were used between 343-393 K. The vapor pressures of the pure and aqueous solutions of DESs were calculated by different equations of state based on "ϕ-ϕ" or "γ-ϕ" γ-ϕ approaches. Additionally, the Voutsas and Wagner models as corresponding-state models were modified to predict the vapor pressure of the pure and aqueous solutions of DES with the total average absolute relative deviations of 7.03, 9.08% and 5.47, 7.15%, respectively. Moreover, the validity of vapor pressure calculation using the two modified models was checked using a linear equation for the average specific heat capacity of different DESs (23 classes of DESs) between 278.15-353.15 K. Results showed that the total average absolute relative deviations of the specific heat capacity of DESs, using the Modified-Voutsas and Modified-Wagner models from the experimental data, were 4.128 and 4.056%, respectively.
