In this work, the protective effect of new nitrogen, amine and phosphorus containing inhibitors synthesized on the basis of local raw materials and bottoms from the vacuum distillation of monoethanolamine in the chemical industry of the Rapublic of Uzbekistan was studied. It has been shown that a multi-component inhibitor containing hydroxyethyldendiphosphonic acid (HEDP), sodium hydroxide, zinc oxide, glycerol, water, and monoethanolamine vacuum distillation residue (COMEA) can be used to protect steel equipment and pipelines in the oil and gas industry. The change in the intensity of the absorption spectra of active functional groups of inhibitors is discussed by IR spectroscopy. Parameters such as corrosion current, stationary potential, corrosion rate, degree of protection, and the value of effective activation energy ∆E_eff are determined corrosion.

The relevance of the topic in the article, the distribution of Acridotheres tristis, mating characteristics and its study, the duration of the research and the methods used in the work, the number of nests found, nesting places, mating places and their number, mating, breeding behavioral responses, number and location of nests, nesting interspecific relationships, nesting duration and use, nest shape, dimensions, nest location, nest construction, nest components and morphometric dimensions, egg laying and duration and brood care during incubation, changes in the egg, hatching, chick size, growth and development, reproduction images, relationship of the new generation to the nest , information about the night, relations with historical monuments, biological characteristics such as nutrition and food types and their importance were studied.

In this article, there are opinions about the physiology of resistance and growth of plants, its structure and environmental conditions.

The article shows the relevance of the topic, the distribution of Pica pica bactriana, meeting characteristics and its study, the duration of the research and the methods used in the work, the number of nests found, nesting places, meeting places and their number, singing, mating. behavioral responses to breeding, number and location of nests, nesting interspecific relationships, nesting duration and use, nest shape, dimensions, nest location, nest construction, nest components and morphometric dimensions, oviposition and duration and brood care during incubation, changes in the egg, hatching, chick size, growth and development, images of reproduction, relation to the nest of the new generation Its biological characteristics and importance, such as its habitat, information about its nighttime, relationship with historical monuments, nutrition and food types, have been studied
