AMMONIUM SALT OF AN ALKENYLSUCCINIC HALF-AMIDE AND THE USE THEREOF AS CORROSION INHIBITOR IN OIL AND/OR GAS PRODUCTION TECHNOLOGY

摘要

An ammonium salt of an alkenylsuccinic half-amide of formula (I) below <IMG> in which R1 denotes H or a C6-C18-alkenyl radical, provided that the radicals R1 a re not both H or both C6-C18-alkenyl, X denotes a group of the formula -NHR2 or -NR2R3, in which R2 and R3 denote C1-C6-alkyl, cycloalkyl or a heterocyclic ring attache d to the nitrogen atom via an alkylene chain, and A denotes XH or a different primary, secondary, or tertiary amine, for example an alkanolamine or a polyamine, and the use thereof as a corrosion inhibitor in oil and/or gas production technology.
