IUPAC name
Naphthenic acids, consisting of an acidic (naphthenic) fraction (70-95%) composed mainly of C8-C20 and 0-3 rings and a non-acidic (petroleum) fraction (5-30%), composed mainly of C12-C22, <10% aromatics, with a boiling range of approximately 160-350°C.
Identifier:
other: Molecular formula
For the acidic (naphthenic) fraction: CnH2n+zO2, where n = carbon number and z = homologous group series number: z = 0 when no ring structures are present, z = -2 when 1 ring is present, z = -4 when 2 rings are present etc. For the non-acidic fraction: not applicable
