Abstract

The water solubilities (Sw) at various temperatures from 283 K to 308 K and 1-octanol/water partition coefficients (Kow) for four brominated benzenes (1,4-dibromobenzene, 1,2,4-tribromobenzene, 1,2,4,5-tetrabromobenzene, and hexabromobenzene) were measured by either the generator-column or the shakeflask method and the high-performance liquid chromatography method, respectively. These solubility data revealed not only the temperature dependence of Sw, in the form of the enthalpy of solution (Delta;solH), but also the effect of bromine substitution on Sw and Delta;solH. To estimate the activity coefficients (γw) of the brominated benzenes in water from the present Sw data, enthalpies of fusion and melting points for those compounds were measured with a differential scanning calorimeter. Henry's Law constants (Hw) of the brominated benzenes were derived assuming that the obtained γw represented the infinite dilution activity coefficients (γw). Some physicochemical characteristics of brominated benzenes were also suggested by comparing the data in this study with that of chlorinated benzenes in the past studies.
