Abstract
Using gas-liquid chromatography (GLC), activity coefficients at infinite di lution have been measured for 37 solutes (alkanes, alkenes, cyclic hydrocar bons, aromatic hydrocarbons, alcohols, ketones, ethers, aldehydes, eaters, and halocarbons) in the solvents epsilon-caprolactone and ethyl benzoate. T he measurements were carried out in the temperature range between (303.15 a nd 343.15) K. The gamma(infinity) values obtained were compared with publis hed data, and the observed temperature dependence of the limiting activity coefficients was confirmed using excess enthalpy data.
