All the cis octadecenoic esters have been converted to cyclopropane compounds by reaction with zinc-copper couple and di-iodomethane. Their gas-liquid chromatographic behaviour on four liquid phases is described. Six isomers (2,3-; 3,4-; 4,5-; 15,16-; 16,17 -; and 17,18 -) have distinctive nuclear m

The chromatographic properties of the cis and trans methyl octadecenoates and of some C12 and Cls acetylenic esters on thin layers of silica impregnated with silver nitrate and on some GLC systems are reported. The possibility of identification and separation of these isomers is discussed.
