ABSTRACT

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 greater than cyclohexane greater than ethyl acetate greater than (n-butanol, acetone) greater than isobutyl alcohol greater than n-propanol greater than isopropyl alcohol. The obtained solubility data of 1,3,5-trichlorobenzene in the studied solvents were correlated by using modified Apelblat equation, h 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 (solH0) and the excess enthalpy for 1,3,5-trichlorobenzene in eight pure solvents, were obtained.
