Abstract (en)
[origin: EP0031924A1] 1. The use of alkanolamine salts of amic acids of the formula (I) see diagramm : EP0031924,P7,F3 where the circle denotes a mononuclear aromatic ring or a mono- or bicyclic aliphatic ring system having 5 or 6 carbon atoms per ring, R**1 is isoalkyl whose longest chain has 6 to 8 carbon atoms and which has a total number of 8 to 12 carbon atoms, and R**2 is alkyl of 1 to 4 carbon atoms or hydrogen, the carboxyl and carbamoyl groups being arranged adjacent to one another, as corrosion inhibitors in aqueous systems.
