| Abstract: | Infinite dilution activity coefficients of nitrotoluene isomers in the liquid crystal solvents MPBOB and MPBH_xB were determined with gas-liquid chromatography method. From these coofficients, enthalpy of solution and entropy of solution, excess enthalpy and excess entropy were calculated, Finaly, the selectivity of the liquid crystal solvents were interpreted in terms of the thermodynamic resules. |
