Solubility Measurement and Model Calculation of Fluorene in Six Binary Solvents from 288.15 to 328.15 K
JOURNAL OF CHEMICAL AND ENGINEERING DATA(2024)
摘要
The solubility of fluorene in six binary solvents (o-xylene + methanol, o-xylene + ethanol, o-xylene + isopropyl alcohol, o-xylene + n-propanol, o-xylene + 2-butanol, and o-xylene + n-butanol) was determined through the gravimetry method over a temperature range of 288.15 to 328.15 K under 0.1 MPa. The results suggested that the solubility of fluorene increased with increasing temperature and the mass fraction of o-xylene in six chosen binary solvents. Moreover, the solubility data of fluorene was fitted by four mathematical models (the modified Apelblat model, the CNIBS/R-K model, the modified Apelblat-Jouyban-Acree model, and the NRTL model). The values of average relative deviation (ARD) of the four models were all proven to be less than 5%, which indicated that these mathematical models were appropriate to simulate the solubility data of fluorene in the six selected binary solvents.
