INHIBITOR OF CARBON STEEL CORROSION IN OXYGEN WATER SOLUTIONS

摘要

FIELD: carbon steel protection. SUBSTANCE: inhibitor has: morpholine (70.00-100.00), cobalt sulfate (0.75-1.50), having a metal anion of changeable valency (4.00-6.4), antioxidant (1.50-12.5) in mass shares. Sodium molybdate and/or sodium chromate are used as having a metal anion of changeable valency salt and hydroquinone and/or p-benzoquinone, ionone, oxime (diisopropoxyphosphoryl) carbonyl chloride, n-butyl (diisopropoxyphosphoryl) formamidoxim, 3-diisopropoxyphosphoryl-5-isopropoxycarbonyl-isoxazole, mixture of 3-diisopropoxyphosphoryl-5-methoxycarbonyl-isooxazole and 3-diisopropoxyphosphoryl-4-methoxycarbonyl-isooxazole. EFFECT: inhibitor is effective for carbon steel protection against corrosion. 2 cl, 2 dwg
