“…It is worth noting that a large number of organic compounds with anticorrosive, bactericidal, and other properties have been discovered [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. While using such compounds as corrosion inhibitors, the following can be observed: the formation of chemisorbed layers on the metal surface and a sharp decrease in the rate of corrosion.…”

A series of 1-(4-(2-allylphenoxy)butyl)piperidin-1-ium halides (4a-d) was synthesized and characterized via spectroscopic methods (FTIR, 1 H NMR). The corrosion inhibition of the synthesized halides on carbon steel in water-salt-hydrocarbon environment, saturated with H2 S, was investigated. For this purpose, a series of techniques such as gravimetric measurement, potentiodynamic polarisation, and scanning electron microscope (SEM) were used and some thermodynamic parameters of corrosion process (Δ G ads. , ΔH 0 ads. , Δ S 0 ads. ) were evaluated. The steel surface was checked by SEM, and the steel surface showed good surface coverage. The results showed that the synthesized compounds at the concentrations 125, 150 mg ×L -1 have corrosion inhibition activity of 78%–95% by gravimetric measurements and 81%–92% by potentiodynamic measurements at 100, 150 mg ×L -1 . The biological activity was examined against sulphate-reducing bacteria (SRB). It was revealed that at the concentration of compounds 4c and 4d, 100 mg ×L -1 , the antibacterial activity was 100%.

“…Such an interpretation indicates the need to abandon the metaphysical understanding of the nature of law and to adopt law in the social life. By that time in China the tradition of "judgment of conscience" was replaced by criminal laws [10]. Certainly, there are certain followers of natural law, who assert that the value of a law must be recognized by a citizen consciously and independently, and not in unconscious passivity, when a person is forced to submit by external violence.…”

The article contains an analysis of the essence of ethical standards of professional activity. The author substantiates the expediency of applying an existential approach to understanding ethical standards. The creation of ethical codes in post-industrial society is a factor in the consolidation of professional social groups. The author argues that the transformation of ethical standards in the legal norm is possible, subject to the addition of a certain sanction. The article contains description of the features of the synthesis of ethical and legal components of the social norm.Key words: ethical codes, social norms, legal norms, ethical norms, management.
