1. The naphthene hydrocarbons, except for five-membered, were identified by their catalytic dehydrogenation and subsequent analysis of the secondary aromatic hydrocarbons. Cyclohexane and its homologs were identified in the benzene fraction of petroleum by the chemical methods and by spectroscopy. 2. After the marked predominance of the methylcyclohexane, 1,3-dimethylcyclohexane predominates among the disubstituted derivatives. After it follows 1,4-dimethylcyclohexane and then 1,2-dimethylcyclohexane. 3. The presence of cyclohexane homologs, from the monosubstituted to tetraalkylcyclohexanes, in the kerosene-gasoil part of the petroleum was established by means of the spectroscopic and picrate methods. Decalin and its homologs were identified. Among the decalin homologs dimethyldecalin predominates. 1967 Consultants Bureau.
