Gas chromatographic analysis of aliphatic alcohols, diols and ethers using aromatic polymers

Abstract

1. The gas-solid separations of alcohols, diols and ethers on porous aromatic polymers are essentially the same as those using gas-liquid separation on Celite-Apiezon L columns, although the retention times on the latter are much shorter. 2. For liquids with similar boiling points the order of elution is diol, alcohol, ether, which reflects their increasing solubility in the polymer or in Apiezon L. 3. Within a class of compounds there is a linear relationship between long tr and boiling point of the eluent. Small divergencies from linearity arise from changes in the structure of the alkyl sidechain. 4. Modifying PAR-1 with polyethylene glycol has little effect on separation of alcohols and ethers, and the behaviour of the resulting column contrasts strongly with the Celite-PEG 1500 column. 5. Diols are separated on aromatic polymers (e.g. PAR-1) without decomposition. © 1968.
