Mutual Solubilities and Vapor Pressures for Binary and Ternary Aqueous Systems: Final Report

摘要

An apparatus has been constructed for measuring mutual solubilities and vapor pressures for aqueous-organic liquid-liquid systems in the region ambient to 200 sup 0 C. Both liquid phases are sampled and analyzed using gas chromatography. Special care must be taken to assure reliable sampling because mutual solubilities are very small; it is especially important to avoid entrainment, phase change (due to temperature gradients or pressure drop) and adsorption when removing samples for chemical analysis. Experimental results are reported for the temperature range 100 to 200 sup 0 C for binary aqueous mixtures containing benzene, toluene, m-xylene, and thiophene, and for ternary aqueous mixtures containing benzene and pyridine. The binary results are in good agreement with diverse data reported in the literature. 10 refs., 7 figs., 5 tabs. (ERA citation 12:025388)
