Synthesis and Inhibition Performance Evaluation of Two Sebacic Acid Imidazoline Quaternary Ammonium Salts
Abstract:
Two sebacic acid imidazoline quaternary ammonium salts,sebacic acid-salicylic acid imidazoline quaternary ammonium salts(SSAI) and sebacic acid imidazoline quaternary ammonium salts(SAI),were synthesized and their inhibition action and adsorption behavior on N80 steel in 1 mol/L hydrochloric solution were investigated by means of mass loss and electrochemical techniques.It was showed that the two compounds had good corrosion inhibition for N80 steel in 1 mol/L HCl solution.SSAI was found to have a superior inhibition efficiency to SAI.Both SSAI and SAI were mixed-type inhibitors and mainly inhibited anode process against N80 steel in 1 mol/L HCl solution.The experimental results revealed that the adsorption processes were exothermic reaction and belong to chemical adsorption.
