“…To verify the accuracy and reliability of the experimental apparatus and experimental method, the determined solubility of AA and SA in cyclohexanone and HAc would be compared with the published data reported. [13][14][15][16][17]19,21,23 As shown in Figures 2 to 5 and Table 2, the experimental measured solubility was in good agreement with the available literature reported data, which indicates the accuracy and reliability of our experimental technique. 3 and summarized in Figures 6 and 7, in which ω 1 is the mass fraction of GA in GA + cyclohexanone and GA + HAc solvents and x represents the mole fraction solubility of AA in solvent mixtures.…”

In this work, the solubilities of adipic acid and succinic acid in glutaric acid + cyclohexanone and glutaric acid + acetic acid mixtures were measured respectively by using the laser dynamic method under atmospheric pressure, in which the temperature ranged from 296.15 to 340.85 K and the mass fraction of glutaric acid in the binary solvent mixtures ranged from 0.00 to 0.30. The effects of glutaric acid on solubility of adipic acid and succinic acid have been discussed. It is found that the effects of glutaric acid on the solubility of adipic acid and succinic acid were negative and that with the increasing mass fraction of glutaric acid in the mixtures the solubilities of adipic acid and succinic acid would decrease. With the gradual increase of temperature, the measured solubility of adipic acid and succinic acid in glutaric acid + cyclohexanone and glutaric acid + acetic acid mixtures would increase at the constant proportion of solvent mixtures. Then the experimental data were wellcorrelated by the modified Apelblat equation and the modified nonrandom two-liquid (NRTL) activity coefficient models, in which the average relative deviation (ARD) were less than 2.50%, and the values of the solubility calculated showed good agreement with the experimental observation. The interaction parameters of AA and GA and SA and GA were determined first in this work.

In this study, solubility and degradation of paracetamol were examined using subcritical water. The effect of temperature and static time was investigated during the solubility process in subcritical water at constant pressure (50 bar). The experimental results showed that temperature and static time have crucial effects on the degradation and solubility degrees. The maximal solubility of paracetamol was obtained at 403 K as (14.68±0.74)×10 3. An approximation model for the solubility of paracetamol was proposed. O 2 and H 2 O 2 were used for the degradation of paracetamol. The maximum degradation degree was found as 68.66±1.05 % and 100±0.00 % using O 2 and H 2 O 2 , respectively.

“…Fan measured the solubilities of AA in several solvents, such as cyclohexanone, cyclohexanol, acetic acid, N , N -dimethylformamide, dimethylacetamide, and dimethyl sulfoxide at the temperature range of 290.80–355.15 K . Shen measured the solubilities of AA in cyclohexanone + cyclohexanol mixtures at the temperature range of 303.15–349.45 K, cyclohexane + cyclohexanol mixtures at the temperature range of 304.15–339.45 K, and cyclohexane + cyclohexanone mixtures at the temperature range of 304.85–342.45 K . Yu measured the solubilities of AA in cyclohexanol + cyclohexanone solvent mixtures at the temperature range of 303.0–353.0 K and cyclohexanone + cyclohexane solvent mixtures at the temperature range of 303.0–378.5 K .…”

Measurement and Correlation for Solubilities of Adipic Acid, Glutaric Acid, and Succinic Acid in Dimethyl Adipate + Methanol Mixtures

et al. 2017

The solubilities of adipic acid, glutaric acid, and succinic acid in dimethyl adipate + methanol solvent mixtures were measured by the method of dynamic laser under 101.3 kPa. The mass fraction of dimethyl adipate in the solvent mixtures ranged from 0.0 to 1.0, and the temperature ranged from 283.95 to 328.15 K. It was found that with the increase of mass fraction for dimethyl adipate in mixed solvents, the measured solubilities of adipic acid, glutaric acid, and succinic acid would decrease at the same temperature, and with the gradually increase of temperature the measured solubilities of adipic acid, glutaric acid, and succinic acid would increase at the constant proportion solvent mixtures. The experimental data were correlated by the Apelblat model, λh model, and the modified nonrandom two liquid activity coefficient model. Results showed that the largest values of relative average deviation and root-mean-square deviations obtained by the three models were 4.49% and 0.35%, respectively. The three models were proven to give a good representation of the experimental solubilities results. The result of Akaike Information Criterion (AIC) analysis shows that the Apelblat model is the best model to correlate the solubilities of adipic acid and succinic acid and the λh model is the best model to correlate the solubilities of glutaric acid in dimethyl adipate + methanol mixed solvent.
