N2 - The solubility of 2,3,4,5-tetrabromothiophene were measured in methanol, ethanol, propan-1-ol, butan-1-ol, toluene, ethyl formate, ethyl acetate, trichloromethane and oxolane within the temperature range between 278.05 K and 325.15 K under atmospheric pressure by gravimetric method. The solubility of 2,3,4,5-tetrabromothiophene in those selected solvents increased with increasing temperature. The solubility data were correlated with the van't Hoff equation, the modified Apelblat equation and the λh equation. The thermodynamic properties of the solution process, including the Gibbs energy, enthalpy, and entropy were calculated by the van't Hoff analysis and the Gibbs equation. The experimental results showed that ethyl acetate had the potential as a better solvent in the re-crystallization process of 2,3,4,5-tetrabromothiophene.
