Vapor Pressures for 1,4-Dioxane + Tetrabutylammonium Nitrate,Water + TetrabutylammoniumNitrate,and 1,4-Dioxane + Water + Tetrabutylammonium Nitrate

摘要

The vapor pressures of the 1,4-dioxane + tetrabutylammonium nitrate and water + tetrabutylammonium nitrate systems have been measured at different salt molalities.The vapor pressures of the 1,4-dioxane + water + tetrabutylammonium nitrate system have also been measured at 11 constant salt molalities (0.100,0.250,0.500,0.750,1.000,1.500,2.000,2.500,3.000,3.500,and 4.000) mol centre dot kg~(-1).These systems have been studied at (288.15,298.15,and 308.15) K with a modified Othmer still.The electrolyte nonrandom two-liquid model was used for the calculation of the activity coefficients of solvents in the binary systems.
