Состав соединений, окклюдированных асфальтенами нефтей различной химической природы

Compounds occluded by asphaltenes of methanonaphthenic oil from the Krapivinskoye field and naphthenoaromatic oil from the Usinskoye field are investigated using the hydrogen peroxide-acetic acid system. The study has found that their composition contains normal and branched alkanes, n- alkylcyclohexanes, n-alk-1-enes, steranes, terpanes and n-alkanoic acids which are similar in structure. The presence of alkyl- substituted benzenes and alkylnaphthalenes in the composition of captured compounds is a distinguishing feature of naphthenoaromatic oil asphaltenes
