Infinite Dilution Activity Coefficients in Ethylene Glycol and Ethylene Carbonate
Abstract
Infinite dilution activity coefficients (γ∞) have been determined by using a gas−liquid chromatography (GLC) technique for benzene, toluene, methanol, ethanol, 2-propanol, and acetaldehyde in ethylene glycol and ethylene carbonate in a range of temperatures from 50 to 110 °C. In the literature, there were no reported data for γ∞ for any of the studied solutes in ethylene carbonate or for acetaldehyde in ethylene glycol. A few γ∞ data were available for benzene, toluene, methanol, and 2-propanol in ethylene glycol, but they were limited to a low-temperature range (<70 °C). The measured γ∞ data in this work therefore provide a good source of γ∞ data in the higher temperature region.
