• 摘要：采用反相高效液相色谱法间接测定了18种芳烃化合物的无限稀释活度系数(γ^-),并利用γ^-估算其辛醇/水分配系数、水溶解度、亨利定律常数,所得结果与文献值、计算值基本一致.

• Abstract：Reversed-phase high performance liquid chromatography was used in indirect determination of the infinite dilution activity coefficients of 18 aromatic hydrocarbons. The results were used to estimate N-octanol/water partition coefficients, water solubilities and Henry’s Law constants of those chemicals. No significant differences were found between calculated values and those in literature.

• Key words：activity coefficient  partition coefficient  water solubility  Henry’ s constant  HPLC.
