Popis:	A solid support has been developed for the gas-liquid chromatography of pyridines, superior to Chromosorb or Celite 545; symmetric peaks were obtained when nonpolar substrates were used. The solid support was prepared from a commercial detergent by heating it and then extracting it with petroleum ether. The porous residue was used as a liquid substrate carrier. The new solid support was used to study the selectivity of several nonpolar and slightly polar liquid substrates. Decided differences in the selectivities of the liquid substrates permit a wide choice in the use of these substrates for separations of pyridines. The study on the selectivity of the liquid substrates was used to select two columns employed in series to separate a test mixture of 14 pyridines.
