METHOD FOR PRODUCTION OF METAL CORROSION INHIBITOR |
摘要 |
FIELD: protection from corrosion; may be used in various industries. SUBSTANCE: method involves reaction of hexamethylene diamine with phosphoric acid and carbamide in the presence of glycerin. Reagents are used in the following more ratio: hexamethylene diamine:phosphoric acid:carbamide: : glycerin = 1.0 : 0.67-2.0 : 2.0-2.5 : 0.2-0.5. Produced corrosion inhibitor in concentration of 25-100 mg/l provides for protective effect of 83-99% in natural water with total salt content of 200 ml/l. EFFECT: higher efficiency. 2 tble
