Fatty acid pyrrolidides have been found to have unusual gas chromatographic properties on a polar stationary phase of the Carbowax type. In particular, exceptional resolution of positional isomers was achieved, and in contrast to methyl esters, unsaturated isomers with double bonds in position 5 or earlier eluted before the corresponding saturated fatty acid derivative.
