Activity Coefficients at Infinite Dilution of Alkanes, Alkenes, and Alkyl Benzenes in Glycerol Using Gas−Liquid Chromatography

Abstract

The activity coefficients at infinite dilution, γi∞, for 16 organic solutes, alkanes, alkenes, and alkyl benzenes in glycerol, have been measured by the gas−liquid chromatographic method at five temperatures from (303.15 to 343.15) K. The overall uncertainty was estimated to be about 5 %. The partial molar excess enthalpies at infinite dilution, HiE,∞, of the solutes in glycerol were also derived from the temperature dependence of the γi∞ values.
