摘　　要：由肉桂醛和苯胺合成席夫碱缓蚀剂,通过静态失重法、电化学测试法研究了在15%盐酸溶液中,席夫碱缓蚀剂对N80钢的缓蚀性能。结果表明,加入质量分数1.0%的席夫碱缓蚀剂,钢片的腐蚀速率降为1.637 2 g/(m2·h),席夫碱缓蚀剂为阳极抑制型缓蚀剂,能自发吸附在碳钢表面,符合Langmuir吸附等温式。Schiff was synthesized with cinnamaldehyde and aniline. The inhibition action and comparison of Schiff base on N80 steel which immersed in 15% hydrochloric acid solution was investigated by means of mass loss method and electrochemical test. The mass loss method result showed that corrosion rate could reduced to 1. 637 2 g/（ m2·h） with 1. 0% Schiff. Schiff was anodic corrosion inhibitor,and was adsorbed on the surface of mild steel spontaneously. Furthermore,the adsorption of Schiff base follows Langmuir isotherm law.
