Separation of a series of positional and geometrical isomers of olefinic aliphatic primary alcohols and acetates by capillary gas chromatography

A general procedure has been developed for the separation of the isomers of many of the olefinic aliphatic insect pheromones using glass capillary gas-liquid chromatographic columns. Four stationary phases containing varying amounts of cyano-propyl and two polyoxyethylene phases were investigated for the separation of positional and geometrical isomers of a series of mono-unsaturated primary acetates and alcohols. Based on the data obtained a procedure has been developed which permits the prediction of elution order and resolution for many di-unsaturated pheromones.
