摘要:

Solution enthalpies of 2,3,4,5,6-pentafluoraniline in CCl4as well as in the solutions of tetrahydrofuran and hexamethylphosphoric triamide have been measured. From the obtained data and spectroscopically determined equilibrium constants the enthalpies of the complex formation of 2,3,4,5,6-pentafluoroaniline with one and two molecules of tetrahydrofuran and hexamethylphosphoric triamide have been calculated. The results yielded from the combination of calorimetric and spectroscopic data have been compared with those obtained using the i.r. method only.
