SummaryDuring gas chromatography on a polyester column, the principal effect of bromine substituents on a fatty ester molecule was to increase the retention time in proportion to the increase in molecular weight. Secondary effects arose from configurational isomerism. Methyl threo-9,10-dibromooactadecanoate was retained longer than the erythro diastereoisomer. The chromatographic difference between diastereoisomers was attributed to a change in dipole moment.
