ISOTHERMAL LIQUID-VAPOR-EQUILIBRIUM OF THE HEXAMETHYLPHOSPHOROTRIAMIDE-BENZENE AND HEXAMETHYLPHOSPHOROTRIAMIDE-TOLUENE SYSTEMS

The authors have measured the vapour pressures of the binary systems hexamethylphos-phorotriamide (HMPT) + benzene and HMPT-toluene. The measurements were carried out using an isoteniscope built by themselves. The vapour pressures and excess Gibbs free energies of both systems are given. Excess entropies are calculated from GE values previously determined and HE values previously measured in the laboratory. © 1990.
