The organic corrosion inhibitor is one of the most economical and effective methods to inhibit the corrosion of metal materials.Indoles are typical organic corrosion inhibitors,but their application is limited for their low water solubility.In this paper,a new schiff base-indoles inhibitor was designed that could be soluble in acid by introducing an acid soluble functional group(-C=N-)to increase the water solubility.And the synthesis process,structure characterization and corrosion inhibition performance test of schiff base-indoles inhibitor were also design.It is intended to provide the research object for the study of corrosion inhibitor and the method for solving the industrial corrosion problem.
