“…And then, the glass vial was put into the jacketed glass crystallizer that had reached the preset temperature. The mixtures were agitated constantly for 12 h to reach the solid–liquid equilibrium state by the magnetic stirrer apparatus and left for 4 h to settle the solids to ensure complete stratification of solid and liquid phases. − About 3 mL of saturated clarified solution of the glass vial was extracted through a precooled/heated syringe (with a 0.22 μm organic membrane filter) into a preweighed beaker and weighed with an electronic balance (model AL204, Mettler Toledo, Switzerland) with an accuracy of ±0.0001 g. Finally, the beaker was put into a vacuum-drying oven at 323.15 K until the solvents dried completely. After repeating each group of experiments three times, the final result was the arithmetic average of the solubility data from the three parallel experiments.…”

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.
