The group of compounds belonging to the neutral oils of the high-boiling fractions of shale tar has been characterized with the use of chemical analysis and IR and PMR spectroscopy. The mean characteristics of the molecular structures have been determined for narrow fractions of the neutral oils. The absence of fractions has been shown both from the degree of aromaticity and the arrangement and type of alkyl substituents in the aromatic nuclei and also from the nature of the functional oxygen groupings. The fractions boiling at 400-450/sup 0/C are distinguished by an increased content of chemical structures characteristic for aromatic ketones, quinoid groupings, and alkylated phenols. Characteristic for them is a higher aromaticity and the presence of long aliphatic substituents in the nuclei. The combination of these molecular structures in the high-boiling fractions of the neutral oils must be regarded as an active principle determining the efficacy of the anticorrosion action of a shale tar additive.
