Equilibres liquide-vapeur isothermes de melanges binaires de la piperidine et de la N-methyl piperidine avec certains ethers (original) (raw)

The authors have measured the vapour pressure of the four binary systems, piperidine + tert-butyl methyl ether, piperidine + 1,4 dioxane, piperidine + tetrahydropyrane and Nmethyl piperidine + tert-butyl methyl ether. The measurements were carried out using an isoteniscope built by J. Jose [1]. The vapour pressure, excess Gibbs free energies at 298.15, 303.15, 313.15, 323.15, 333.15 and 343.15 K, are reported for these mixtures. The exeess Gibbs free energies have been fitted to the Redlich-Kister equation.
