phase equilibria of hydrates of furan, acetone, 1,4-dioxane, tetra n-butyl ammonium chloride and tetra n-butyl ammonium floride

in this communication, we first report experimental hydrate dissociation pressures for the methane/ carbon dioxide + furan/ acetone/ 1,4-dioxane + water and the methane + tetra n-butyl ammonium chloride (tbac) + water as well as the methane /carbon dioxide + tetra n-butyl ammonium floride (tbaf) + water systems in the temperature ranges of (269.9 to 303.3) k. an isochoric pressure-search method was used to generate the experimental data. the hydrate dissociation data are compared with the corresponding literature data and the predictions of a previously reported thermodynamic model and acceptable agreement is observed.
