摘要

Abstract

In this work

the solubility data of 9-fluorenone in 11 pure solvents (methanol

ethanol

-propanol

iso

-propanol

-butanol

iso

-butanol

acetonitrile

ethyl formate

ethyl acetate

dimethyl sulfoxide

-hexane) were measured by the gravimetric method from 278.15 K to 318.15 K under atmospheric pressure. The results showed that the solubility of 9-fluorenone in all tested solvents increased with the raised temperature. The solubility data were correlated by the modified Apelblat equation

λh

model and NRTL (non-radom two fluid) model. The average relative deviation (ARD) correlated by three thermodynamic models in different solvents was all below 5%

which indicated that the three thermodynamic models fit the solubility data well. Furthermore

the mixing thermodynamic properties of 9-fluorenone in pure solvent systems were calculated

via

NRTL model. The results indicated the dissolution process of 9-fluorenone is spontaneous and entropically favorable. The solubility and the mixing thermodynamic properties provided in this paper would play an important role in industrial manufacture and follow-up operation of 9-fluorenone.
