A Study of the Behavior of Alkyl Side Chains Phenosl and Arenes in Polar and Nonpolar GC Stationary Phases

Popis výsledku v původním jazyce

Gas chromatographic measurement of the relative retention times of alkyl-substited and phenlos on capillary columns at temperature of 125 °C - 140 °C have shown that logarithms of retention times increase bi-linearly with the number of carbon atoms in the molecule. It was found that in a high density stationary phase, the longer of this phase affecting molecules during their thermal and diffusion motion. Consequently, common conventional aromatic-aliphatic molecules become new molecules with quasi-alicyclic rings. In comparison with the conventionally conceived molecules, the resulting aromatic-quasi-alicyclic molecules are charactized by rather different the retention characteristic. Moreover, cyclization facilitates the mixing of n-alkyl phenlos withhigh molecular stationary phases, because the thermodynamic condition for mixing is better fulfilled.
