ABSTRACT:
Corrosion of metals in contact with liquid systems is reduced by adding to the system a small amount of an amino carboxylic acid containing at least one hydrophobic group in combination with another nitrogen containing compound. The other compound is preferably an ether amine or a quaternary ammonium compound which also contain hydrophobic groups. The combination of substances is particularly useful for preventing corrosion in different areas of oil recovery and in petroleum industry.
