ACID CORROSION INHIBITOR

摘要

FIELD: protection of metals against acid corrosion with use of chemical reagents. SUBSTANCE: invention can be recommended for employment in petroleum and petrochemical industries for prevention of corrosion of steel. Composition of inhibitor includes product of condensation of primary or secondary amines, acetophenon and formaldehyde in molar proportion 1:1-2:1.2-2.4 to reduce cost of inhibitor and to make it more efficient in acid environment. EFFECT: reduced cost and increased efficiency of proposed inhibitor. 1 tbl
