ACID CORROSION INHIBITOR

摘要

FIELD: protection of metals against acid corrosion with use of chemical reagents. SUBSTANCE: invention can find use in petroleum and petrochemical industries. Composition of proposed inhibitor includes product of condensation of primary or secondary amines, acetophenon and formaldehyde in molar proportion 1: 1-2: 1.2-2.4 to make inhibitor cheaper and to enhance its efficiency in acid environment. Urotropine in the amount of 10-90 per cent by mass is added into prepared composition. EFFECT: cheapened inhibitor with enhanced efficiency in acid environment. 1 tbl
