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.
