Spectroscopic and thermodynamic study of hexafluorobenzene + aromatic amine complexes

Abstract

U.-v. spectrophotometric measurements of the association constants and enthalpies of formation for the complexes formed by hexafluorobenzene with N,N-dimethyl aniline (DMA) and N,N-dimethyl toluidine (DMT) are reported. Enthalpies of mixing of hexafluorobenzene with isopropylcyclohexane at 323.15 and 343.15 K are also reported. The spectrophotometric results correlate with the present enthalpy of mixing data taken in conjunction with the enthalpies of mixing for the hexafluorobenzene and amine systems reported previously.¹
