Protective Action Of New Amine-Containing Inhibitors

This study investigates the protective action of newly synthesized amine-containing corrosion inhibitors derived from local raw materials and the distillation residues of monoethanolamine vacuum distillation in the chemical industry of Uzbekistan. It is shown that a multi-component inhibitor containing hydroxyethyldenediphosphonic acid (HEDP), sodium hydroxide, zinc oxide, glycerin, water, and the vacuum distillation residue of monoethanolamine (COMEA) can be used to protect steel equipment and pipelines in the oil and gas industry. Changes in the absorption spectra intensity of active functional groups of the inhibitors were studied using IR spectroscopy. Parameters such as corrosion current, stationary potential, corrosion rate, degree of protection, and effective activation energy (∆E_eff) were determined.
