am2(s): initial mass fraction of component 2 in the binary solvent mixture.
bxl: mole fraction solubility of the solute.
Auxiliary Information
Method/Apparatus/Procedure:
Constant-temperature bath, magnetic stirrer, analytical balance, and ventilated
laboratory hood.
Solubilities were determined by a gravimetric method. Binary solvent
mixtures were prepared by mass and allowed to equilibrate in sealed bottles in a
constant-temperature bath for 2 h with stirring. The stirring was discontinued
and the solid was allowed to settle to the bottom of the container. After 30 min,
an aliquot of the clear solution was removed by syringe, filtered through a
0.2 pim PTFE filter, and transferred to a preweighed glass vial. The glass vial
was then weighed, and the solvent was allowed to evaporate in a ventilated
laboratory hood at ambient room temperature. Once the solvent had
evaporated, the vial with solid residue was weighed until constant weight was
obtained. The solubility was calculated from the mass of the solid residue and
mass of sample analyzed.
