Temperature Dependence of Infinite Dilution Activity Coefficients in Octanol and Octanol/Water Partition Coefficients of Some Volatile Halogenated Organic Compounds

摘要: Infinite dilution activity coefficients and Henry's law have been measured for 11 halogenated C 1 to 3 compounds in 1-octanol above room temperature using a gas-liquid chromatographic measurement method. Then, our earlier data these substances water correlation relating the limiting of substance pure their octanol/water partition coefficients, latter quantities computed. One conclusion from measurements is that octanol studied are only weakly dependent on over range 25 50°C. Also, data, we estimated infinite partial molar excess enthalpies entropies both water.
