INHIBITOR OF ACID CORROSION Russian patent published in 1996 - IPC

FIELD: chemical industry, oil extraction industry, textile industry. SUBSTANCE: inhibitor ЮТЭ-11 provides protection against acid corrosion of ferrous and non-ferrous metals and alloys. as its components inhibitor uses production wastes of several branches of industry, ionegenic nitrogen-bearing organic compound, deoxygenating component and organic dissolvent - homogenizer, in medium of which production of ionegenic compound of amount output takes place. Optimal selected ratio of components in composition mixture allows to produce inhibitor of metals and alloys acid corrosion with wide spectrum of action. Inhibitor is compatible with effective defoamers and foam makers. Inhibitor is used for chemical purification of thermal power equipment from sediments and scale, protection of equipment main metal from aggressive action of acids solutions. Optimal concentration of inhibitor in acid solution is 0.25 - 2.0 kg/m³. EFFECT: improve quality of inhibitor.
