Abstract
Trifluoroacetate (TFA) and trimethylsilyl ether (TMS) derivatives of fatty alcohols ranging in chain length from C14 to C20 were analyzed by gas-liquid chromatography. The TFA and TMS derivatives gave quantitative results for both saturated and unsaturated standard mixtures. Excellent resolution of the TFA derivatives on the polar liquid phase allows quantitation of mixtures containing both saturated and unsaturated alcohols. Analyses were carried out on columns (5-ft × 1/8-in) containing 15% ethylene glycol succinate methyl silicone polymer (EGSS-X) and 5% methyl silicone polymer (SE-30) liquid phases operated at 130° and 190°C, respectively, for both derivatives.
