In this review, published information on the nature and molecular compositions of organochlorine compounds (OCCs), which are found in crude oil and in its refined products, is systematized. The native and added OCCs are reviewed. The formers are concentrated predominantly in high molecular weight resinous-asphaltene substances of crude oil, the latter’s, referred to as light organochlorine compounds, are present in the gasoline fractions. The following chemicals that are used for oil production are regarded as possible sources of OCCs: inhibited hydrochloric acid, acid compounds; organic solvents of asphalt-resin-paraffin deposits, organic solvents served for oil production stimulation, and possible products of a mutual solvent chlorination with hydrochloric acid.

The 13C NMR spectra of samples of heavy crude oil fractions were interpreted. The spectra of all samples were of the same character. In the region of the aliphatic carbon shifts, ten different carbon atom types were discerned; some possible structure types of hydrocarbons were attributed to them and the arrangement of the aromatic rings in a mean molecule of the samples examined was discussed.
