【摘要】：采用甲醛/苯甲醛、苯乙酮和水合肼为原料分别合成了AJ和BJ两种曼尼希碱缓蚀剂。通过静态挂片失重法、电化学测试法等方法研究了在15%HCl(质量分数)溶液中,这两种缓蚀剂对N80钢的缓蚀性能。结果表明:在15%的HCl溶液中,AJ和BJ缓蚀剂对N80钢具有良好的缓蚀作用,且BJ缓蚀剂的缓蚀效果要优于AJ缓蚀剂的;两种缓蚀剂均为阳极型缓蚀剂,都能自发吸附在N80钢表面,其行为均符合Langmuir吸附等温式。
[Abstract]:Using formaldehyde / benzaldehyde, acetophenone and hydrazine hydrate as raw materials, two kinds of Mannich alkali corrosion inhibitors AJ and BJ were synthesized respectively. The results show that AJ and BJ inhibitor have good corrosion inhibition effect on N80 steel in 15% HCl solution, and the inhibition effect of BJ inhibitor is better than that of AJ inhibitor. The two inhibitors are anodic corrosion inhibitors and can be spontaneously adsorbed on the surface of N80 steel. The behavior of the two inhibitors accords with the Langmuir adsorption isotherm.
