| Description |
Three amide derivatives of 1-aminoanthraquinones (AAQs) synthesized from long chain fatty acids were
evaluated for corrosion inhibition efficiency against steel (API 5L-X60) in white petrol–water mixtures
at room temperature by weight loss and electrochemical studies. Potentiodynamic polarization studies
carried out at room temperature on steel (API 5L-X60) in white petrol with water containing 120ppm of
chloride and 50ppm of the 1-aminoanthraquinone derivatives showed that all the investigated compounds
are of anodic type and good corrosion inhibitors in white petrol–water mixtures. Oleic acid
derivative of 1-aminoanthraquinone was found to be the best corrosion inhibitor. It exhibited 86% inhibition
efficiency against the corrosion of API 5L-X60 steel. The surface analysis by AFM indicated the
adsorption of inhibitors on the metal surface. Besides, all the synthesized 1-aminoanthraquinone derivatives
exhibited antimicrobial efficacy against Serratia marcescens ACE2 and Bacillus cereus ACE4.
