INHIBITOR OF METAL CORROSION IN SULFURIC AND HYDROCHLORIC ACIDS

摘要

FIELD: protection of metals from corrosion in sulfuric and hydrochloric acid, more particularly etching of metals in machine building. SUBSTANCE: greater degree of protection of steel, aluminium and titanium from corrosion and greater degree of steel from hydrogen absorption are achieved by using 13.75-16.6 wt % amine and N-(5-butyl-2-furfulidene-(5'-oxy-2'-pyrimidinyl) sulfonylamide as condensation product and adding 23.78-26.6 wt % 2,2-(diaminodiethyl sulfide dihydroiodide to inhibitor, 26.2-93.3 wt % 9-(3,5- dinitrophenyl)acridine and 23.2-36.2 wt % urotropin. EFFECT: improved properties of the inhibitor. 1 tblc
