Retention Characteristics and Enthalpy of Sorption of Esters of 2,2-Dimethylbutury Acid and Aliphatic Alcohols with Linear Structure C1–C10

Gas–liquid chromatography on a non-polar phase is used in the 393.2–473.2 K range of temperatures to determine the retention characteristics and enthalpies of sorption for 10 esters of 2,2-dimethylbutyric acid and linear alcohols C1–C10. A linear dependence of the indices of retention on temperature and the number of carbon atoms in the alcohol molecule is shown for all studied ethers. Enthalpies of evaporation are calculated, and the excess enthalpies of the mixing of ethers are determined.
