Abstract

The separation of isomeric C 15–C 18 n-alkenes and n-alkanes was studied on high-efficiency glass capillary columns coated with liquid crystalline 4- n-propylbenzoic acid—4',5- n-hexyl pyrimidin-2-yl phenyl ester. The separation was optimized with respect to the stationary phase film thickness and column temperature. The separation system permits better and faster separations of isomeric n-heptadecenes and n-octadecenes compared with previously obtained separations on non-mesogenic and mesogenic stationary phases.
