Capillary gas-liquid chromatography revealed composition of products of catalytic deoxygenation of low-molecular weight acids from crude oils of Soviet deposits. The lower petroleum acids have structures similar to those of the hydrocarbons of light petroleum spirits. These structures would be equivalent to the theoretically possible isomers coming from acids with the carboxyl group mainly in terminal positions. The quantitative distribution of isomeric acids and hydrocarbons conforms to the same mechanisms. Petroleum acids are characterized by a higher content of aliphatic and aromatic structures, but a lower content of alicyclic structures than the corresponding hydrocarbons of light petroleum spirits from the same oil.
