文摘

The solubility of N-ethylcarbazole in (ethanol+petroleum ether) binary solvent mixtures was measured with the temperature changing from 280.15 K to 316.15 K. The experimental data matched the solvent/Redlich-Kister (CNIBS/R-K) equation and the Jouyban-Acree equation. Computational results showed the CNIBS/R-K equation was more suitable than the Jouyban-Acree equation. The solution process in the thermodynamic properties, including the Gibbs energy, enthalpy, and entropy, was calculated by the van’t Hoff analysis.
