Abstract

Gas chromatography is used to study the sorption characteristics and retention of a series of mono-, di-, and triethylene glycol ethers on nonpolar phase DB-1 in the temperature range of 70–180°C. Temperature dependences of the retention indices of the compounds are obtained and their linear character in the investigated range of temperatures is demonstrated. The enthalpies of sorption of the investigated compounds are calculated and analyzed, based on the temperature dependences of the retention factors.
