Gas-chromatographic behaviour of 1-, 2-, 3-, 4-, 5-, 6-, 7-, and 10-cyclohexylnonadecanes (1-8) and 1-cyclopentylicosane (9) was studied. Kovats retention indices (I) on capillary fused silica columns DB-1 and DB-WAX were calculated and complete mass spectra of all the nine isomeric hydrocarbons are described.
