Gas-Liquid Chromatographic Analyses : XVI. Determination of monochlorinated products formed in liquid-phase chlorination of C9-C12, C14, C16 and C18n-alkyl acetates on se-30 and ov-351 quartz capillary columns with temperature programming

Abstract

Aliphatic C9C18n-alkyl acetates were chlorinated with chlorine in the liquid phase in order to obtain monochlorinated products. The products were determined by gas chromatography using non-polar (SE-30) and polar (OV-351) capillary columns. All of the chloro isomers of C9C11, homologues are resolvable on OV-351; for longer chain lengths (C12,C18), the peaks of the mid-chain isomers from the 6-chloro to the (ω - 5)-chloro isomer overlap. On SE-30, additional overlappings of the (ω - 1)- and (ω - 2)-chloro isomers of all esters are detected, however. The retention behaviour of a mixture of all 97 components on polar and non-polar stationary phases was studied and the retention order is discussed. The SE-30 column separated the mixture better, the parent esters and their 1 -chloro and ω-chloro isomers showing the greatest difference in the retention order between the columns used.
