“…A mixture of sulfurous waste is used in the microwave two-component synthesis of organic sulfur derivatives based on various hydrocarbons (8). The addition of elemental sulfur to a mixture of sulfur components and hydrocarbons allowed three-component synthesis under the action of microwave irradiation (10). In this case, the proposed technological unit permits the possibility of obtaining the most promising organic sulfur derivatives from the standpoint of biological activity-polysulfides with a sulfur atom chain length ≥3.…”

“…This situation can be convincingly illustrated by the example of hydrogen sulfide, which is known to be a toxic and corrosive substance, the content of which in the residual products of the secondary processing of high-sulfur raw materials often exceeds the established regulatory requirements [9,10]. For example, in the process of atmospheric distillation of high-sulfur gas condensate, the residue of atmospheric distillation (straight-run fuel oil) is obtained, containing the sulfur waste hydrogen sulfide and thiols, which are used as the main components of commercial fuel oil for heating.…”

A logical-informational model of energy resource-efficient chemical technology for the utilization of hydrogen sulfide and low molecular alkanethiols, which are toxic and difficult to remove sulfur components of residual fuel (fuel oil), is proposed. Based on the IDEF1 methodology and existing knowledge about the technological processes of the demercaptanization of various hydrocarbon raw materials (oils, gas condensates), a scheme for the production of organic sulfur compounds from sulfur waste extracted from fuel oil has been modeled. For a sufficiently complete removal of hydrogen sulfide and low molecular weight alkanethiols, energy- and resource-saving stages of the technological process have been developed, which are implemented by ultrasonic and/or magnetic treatment of fuel oil. It is proposed to use the combined action of two alternative methods of processing fuel oil to increase the efficiency of cleaning fuel oil from sulfur components. For the first time, an approach has been developed to utilize unwanted sulfuric impurities contained in fuel oil by involving electric and microwave synthesis in green technological processes, to obtain practically useful organic sulfur compounds with biological activity. It is shown that the use of one-electron oxidant thiols and hydrogen sulfide in organic media leads to the synthesis of organic disulfides and elemental sulfur. Indirect (with the use of mediators) electrosynthesis contributes to the cyclic conduct of the technological process, an increase in efficiency and a decrease in energy consumption compared to the direct (on electrodes) initiation of sulfur components.

This article is devoted to the study of the levels of public health risk from exposure to vari-ous pollutants, such as carbon monoxide and nitrogen, nitrogen dioxide and sulfur, hydrogen sul-fide, ozone, formaldehyde, benzene, toluene, methane and phenol on the territory of Moscow. It is shown that all the considered pollutants cause harm tothe human body. Averaged data were ob-tained, for the period from 2008-2020, the calculated values indicate a significant level of risk of developing diseases in the residents of the capital that lead to damage to the endocrine system. Causing diseases leading to metabolic disorders in the body, respiratory organs and skin, as well as subcutaneous tissue. Thus, diseases of the endocrine system and metabolic disorders in residents of Moscow, during the period under review, are most influenced by nitrogen oxide and dioxide, carbon monoxide and phenol. Carbon monoxide, nitrogen dioxide, formaldehyde, toluene and phe-nol have the greatest influence on respiratory diseases in humans. The diseases of the skin and subcutaneous tissue are most affected by carbon monoxide, phenol, sulfur dioxide and nitrogen oxide. In this paper, a forecast of the volume of pollutants for 2024 is made. The data obtained indicate that there will be an increase in the concentration of pollutants such as formaldehyde, methane and phenol. Which will lead to adverse effects, both on the soil and on the human body. On the other hand, the results obtained indicate that there is a positive trend towards a decrease in the concentration of carbon monoxide and nitrogen, nitrogen dioxide and sulfur, hydrogen sulfide, ozone, benzene and toluene.
