Abstract

Using various sorbents in gas-liquid chromatography and gas-solid chromatography, the dependence of the retention of diprimary linear diols of the HOCH2(CH2)nCH2−OH type (n=0–4) on different parameters characterizing the physicochemical properties of the diols was studied. As shown, the relationship between the logarithm of the retention volume, or the boiling point, molecular mass, number of CH2-groups, density, refractive index, molecular refraction, and the logarithm of the retention volumes obtained on another stationary phase is either linear or nearly linear. The linear regression coefficients of the various relationships are given.
