Abstract
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 well-correlated by the ...
