摘要/Abstract

摘要： Using a laser detecting system, solubility data were measured for adipic acid dissolved in six pure solvents, namely, cyclohexanone, cyclohexanol, acetic acid, N,N-dimethylformamide, N,N-dimethylacetamide, and dimethylsulfoxide at the temperature range from 293.15K to 353.15K. All these data were regressed by , NRTL, Wilson, and the modified Wilson models. For the study of six, , NRTL, and the modified Wilson models were found to provide an accurate mathematical representation of the experimental results, with overall average absolute relative de-viations between measured and calculated values as 1.74%, 2.06%, and 3.06%, respectively. The results showed that the model is the most suitable for description of the solid-liquid equilibrium containing adipic acid.
