Název v původním jazyce

Temperature dependence of limiting activity coefficients and Henry's law constants of cyclic and open-chain ethers in water

Popis výsledku v původním jazyce

Limiting activity coefficients of seven selected ethers (diethyl ether, tetrahydrofuran, tetrahydropyran, dimethoxymethane, 1,2dimethoxyethane, 1,3-dioxolane, and 1,4-dioxane) in water were measured at several temperatures in the range from 273 to 373 K.Six experimental techniques were employed for the purpose. A comprehensive review is presented of experimental data on the limiting activity coefficients, infinite dilution partial molar excess enthalpies and heat capacities of these aqueous solutes. For each ether, the compiled data were critically evaluated and together with the data measured in this work correlated with a suitable model equation providing adequate simultaneous description of the equilibrium measurements and the calorimetric information. As a result, a recommended thermodynamically consistent temperature dependence of limiting activity coefficients of superior accuracy was established in the range from the melting point to the normal boiling point of water. Analogous
