Retention Indices and Enthalpies of Sorption of Esters of Neopentyl Glycol on DB-1 Stationary Phase

The logarithmic retention indices and the enthalpies of sorption at the average temperature of an experiment and 298.2 K are determined via gas–liquid chromatography using DB-1 stationary phase for esters of neopentyl glycol and С2–С6 monobasic carboxylic acids of linear and branched structure at 423.2–523.2 K. The temperature dependences of the studied compounds’ retention indices are obtained, and the linearity of these dependences in the investigated range of temperatures is demonstrated. The values obtained for the enthalpies of sorption are analyzed.
