Paper Title:
Application of Imidazolinylquaternary-Ammonium-Salt Compound Inhibitor for A20 Steel in Hydrochloric Acid Pickling
  Abstract

To enhance the water solubility and inhibition efficiency of 2-phenyl-imidazoline, a type of imidazolinylquaternary-ammonium-salt(IMA)was synthesized from 2 - phenyl-imidazoline and benzyl chloride.And then the compound inhibitor was manufactured with IMA, potassium iodide, triethanolamine, polyoxyethylene ether and peregal by weight loss through orthogonal experiment. The effect of the compound inhibitoron on corrosion of A20 carbon steel in hydrochloric acid have been investigated in relation to it’s concentration by various corrosion monitoring techniques. Polarization studies showed depression of cathodic and anodic polarization curves in the presence of the compound inhibitor, indicating mixed type inhibition. EIS results show that the changes in the impedance parameters (Rp and Cd) with concentrations of the compound inhibitor are indicative of the adsorption of these molecules leading to the formation of a protective layer on steel surface.
