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 physicochemical properties and production fire-resistant oils based on triaryl phosphates are considered. The method for obtaining butylated fire-resistant oil developed in RD-RN Center is described. The application of this method for resumingthe production of fire-resistant oils and hydraulic fluids based on raw materials available in the Russian Federation is discussed.

The article is devoted to the analysis of one of the activities of the judge – his cognitive activity. Three main components of this type of activity are considered: epistemological, moral and psychological. In the analysis of the epistemological aspect of the cognitive activity of the judge, attention is paid to the justification of the need to achieve the truth during the judicial investigation. The author reveals the reason why there is no common opinion on this issue among lawyers. Moral qualities of the judge necessary for ensuring high quality of cognitive activity of the judge are analyzed. A number of psychological features of cognitive activity inherent in justice activity is revealed.
