摘　　要：通过对多种醛类和胺类化合物的缓蚀性能进行单组分筛选,利用失重法测定腐蚀速率,得到缓蚀性能好的醛类和胺类,将其作为原料,合成一种具有高效缓蚀性能的席夫碱。对该席夫碱进行缓蚀性能研究,结果表明,该席夫碱在盐酸介质中,对碳钢具有良好的缓释效果。采用电化学法确定该席夫碱是一种混合偏阴极型缓蚀剂,具有非常好的抗酸性、耐高温性以及抗时间性能。A kind of schiff base with high - efficency corrosion inhibition performance was com- posed by some aldehyde and amine compound that have excellent corrosion inhibition performa -nce chosed by weight loss method. A conclusion was drawn that the schiff base had good effect on inhibition of carbon steel in hydrofluoric acid medium. The corrosion inhibitor was proved to be a kind of mixed inclined cathode type corrosion inhibitor by electrochemistry method. And it has excellent acid stability, thermostability property and time anti -interference performance
