【 摘 要 】

With the mixed fatty acid obtained by hydrolysis of refined gutter oil, and triethylenetetramine as raw materials, mixed aliphatic imidazoline fatty amine intermediate was synthesized by acylation-cyclization, which was then reacted with cyanamide to synthesize a novel mixed aliphatic imidazoline guanidinium corrosion inhibitors. The optimal synthesis conditions were determined through orthogonal tests: raw materials mass ratio (intermediate: cyanamide) of 8:1.3, reaction temperature of 120° C, reaction time of 4 h, and ethylene glycol monomethyl ether as solvent. The characterization of the product structure by infrared spectroscopy, ultraviolet (UV) spectrum and nuclear magnetic resonance (NMR) were carried out.
