The solubility of 1,3,5-trichlorobenzene in n-propanol, isopropyl alcohol, n-butanol, isobutyl alcohol, cyclohexane, toluene, ethyl acetate, and acetone were obtained experimentally in temperatures ranging from (273.15/280.65 to 308.15) K under a pressure of 0.1 MPa with a chromatographic method. The solubility data of 1,3,5-trichlorobenzene in those selected organic solvents increased with increasing temperature. The order of the solubility data values is as follows: toluene > cyclohexane > ethyl acetate > (n-butanol, acetone) > isobutyl alcohol > n-propanol > isopropyl alcohol. The obtained solubility data of 1,3,5-trichlorobenzene in the studied solvents were correlated by using modified Apelblat equation, λh equation, Wilson model, and NRTL model. The four models all provide acceptable results for the system of 1,3,5-trichlorobenzene in the selected solvents. Furthermore, the thermodynamic properties of solution, including molar dissolution enthalpy (Δ_solH⁰) and the excess enthalpy for 1,3,5-trichlorobenzene in eight pure solvents, were obtained.
