title: Fatty acids. XIII. The gas-liquid chromatographic behaviour of dimethylene-interrupted methyl cis-octadecenynoates.
abstract: All of the dimethylene-interrupted methyl cis-octadecenynoate isomers, except the delta13c,17a isomer, have been prepared by partial hydrogenation of the corresponding methyl octadecadiynoate. Gas-liquid chromatographic analysis of the octadecenymoates has been carried out on Carbowax 20M, DEGA, DEGS, FFAP and Silar 10C stationary phases. The delta3,7 isomers decompose on chromatography. The equivalent chain lengths of all of the remaining methyl cis-octadecenynoates are reported.
