Isothermic vapor-liquid equilibria of binary mixtures of piperidine and N-methylpiperidine with certain ethers

The authors have measured the: vapour pressure of the four binary systems, piperidine + tert-butyl methyl ether, piperidine + 1,4 dioxane, piperidine + tetrahydropyrane and N-methyl 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 excess Gibbs free energies have been fitted to the Redlich-Kister equation.
