NOVEL MOLECULES DERIVED FROM PHOSPHORYLATED 2-PHENYL-IMIDAZOLINES, HAVING HIGH IMIDAZOLINE RING STABILITY AND A HIGH LEVEL OF EFFECTIVENESS AS CORROSION INHIBITORS

摘要

The invention relates to a process involving a reaction between derivatives of 2-phenyl-2-imidazolines or compounds thereof substituted at position 1 with 2-aminoethyl or 2-hydroxyethyl groups with mono or biphosphates of dodecyl in the presence of aromatic solvents or mixtures of aromatic compounds having boiling points between 100 and 200°C, the derived phosphoramides and phosphates being strong corrosion inhibitors.
