any one of a number of cycloalkane hydrocarbons obtaining the general formula CnH2n and found in several petroleums.
Any cycloalkane (or alkyl derivative).
A peculiar hydrocarbon small fraction occuring as a component of some crude petroleums, mainly mixtures of types associated with five- and six-membered concentrated cyclic alkanes, cyclopentane and cyclohexane, getting the general formula CnH2n.
In organic biochemistry, a class-name of a number of hydrocarbons produced by hexahydrobenzene (cyclohexane), C6H12. Quite a few might made synthetically, and a substantial number are observed in petroleum, especially in that through the Baku district.
