CORROSION INHIBITIN OF A COMPOUND IMIDAZOLINE CORROSION INHIBITOR FOR A3 STEEL
复配咪唑啉型缓蚀剂体系的缓蚀性能研究

Imidazoline corrosion inhibitor YQ-01 was synthesized with hexadecanoic acid and diethylene triamine, which then was modified by maleic anhydride, there after the modified YQ-01 was mixed with YQ-02 an asistant agent, finally an corrosion inhibitor YQ-03 was gained. From the results of weight-loss measurement, electrochemical polarization curve and observation by scanning electron microscope, it shows that the corrosion inhibitor YQ-03 suppresses the corrosion of A3 steel in carbon dioxide corrosion system effectively.
