Bis-quaternary ammonium salt is a new kind of cationic Gemini surfactant. Due to its low toxicity ， good surface activity and good water solubility ，it is a promising corrosion inhibitor. According to molecular structure ，bis-quaternary ammonium salt is classified into three categories ：symmetrical alkyl bis-quaternary ammonium salt ，symmetrical heterocyclic bis-quaternary ammonium salt ，and non-symmetrical bis-quarternary ammonium salt. The testing results of corrosion inhibition of such three categories are summarized. The research of bis-quaternary ammonium salt is not systematic ，and future research will focus on environment-friendly bis-quaternary ammonium salt ，inhibition mechanism and industrial applications.
