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