Abstract: | Isobaric heat capacities of synthetic mixtures were determined up to 40 MPa with a modified C-80 Setaram calorimeter equipped with cells designed for high pressures. The system investigated was a pseudo-binary hexane+synthetic cut, the latter consisting of compounds of the three chemical families that occur most frequently in natural effluents (paraffins, naphthenes and aromatics). The additional knowledge of density vs. pressure and temperature affords the specific heat γ ratio. |
