CORROSION INHIBITION PERFORMANCE OF A NEWLY SYNTHESIZED HETEROCYCLIC BISQUATS
含杂环双季铵盐的合成及其缓蚀性能的研究

Bisquats has widely applicable foreground and well corrosion inhibition ability.A kind of new heterocyclic bisquats compound (MBQA)was successfully synthesized with metronidazole as matrix and epichlorohydrin as link agent respectively.Weight loss measurement,potentiodynamic polarization curves,electrochemical impedance spectroscopy and scanning electron microscopy were used to evaluate the corrosion inhibition performance of MBQA in a simulated oilfield water.The experiment results show that it has good water solubility and effectively corrosion inhibition performance.
