Ammonium chloride benzyl quinoline(QA)was synthesized.The corrosion inhibition performance of QA on steel N80 was evaluated in hydrochloric acid system.Synergistic effect with propargyl alcohol(BCC) and JHC-2 on QA were studied.The synergistic effect of non-ionic surfactant OP-10 on the binary complex sys-tem was discussed.By potentiodynamic polarization and electrochemical impedance experiment,the electrochem-ical behavior of QA was studied in the hydrochloric acid system.The results showed corrosion inhibition perfor-mame of QA on steel N80 was obvious in hydrochloric acid system,and the corrosion inhibition rate was up to 93% at the dose of 200 mg·L-1 .BCC and JHC-2 had synergistic effect to QA,and the best ratio of QA∶BCC (JHC-2)was 150∶50.The synergistic effect of OP-10 to the binary complex systems was obvious,and the best ratio of QA∶BCC(JHC-2)∶OP-10 was 150∶50∶20.
