FIELD: protection of metals against acid corrosion by means of inhibitors; pickling of metals and acid cleaning of equipment; power engineering, food-processing industry and other industries.
SUBSTANCE: proposed inhibitor contains the following components, mass-%: furfuryl-3-iodine-4-amino-pyridine,29.4-21.0; 2-amino-4-isopropylamino-6-chloro-pyrimidine,14.7-12.3 and urotropin, 55.8-66.6.
EFFECT: high degree of corrosion protection of steel, zinc and manganese in acids; reduction of hydrogen absorption.
