摘要: 以酮、醛、胺和喹啉、氯化苄为原料,室内分别合成制备了高温酸化缓蚀剂YSH-05和JAY-01。采用静态挂片失重法、电化学方法和扫描电子显微镜对比考察了它们的性能。结果表明,缓蚀剂JAY-01的缓蚀性能优于YSH-05,JAY-01可以适用于135℃下的酸化施工。YSH-05是以抑制阴极过程为主的混合型缓蚀剂,缓蚀剂JAY-01是一种阴极型缓蚀剂。缓蚀剂YSH-05和JAY-01在铁表面的吸附均符合Bockris-Swinkels吸附等温式,它们在钢片表面形成了一层保护膜,有效地抑制了盐酸对N80钢的腐蚀。

Abstract: Two corrosion inhibitors,YSH-05 and JAY-01,are synthesized respectively with ketone,aldehyde,amine and quinoline,benzyl chloride.Their performance is studied by using static weight-loss method,electrochemical polarization curve and scanning electron microscope.The results show that corrosion inhibitor JAY-01 outweighs YSH-05 and JAY-01 can efficiently be used in acidizing operation at 135℃.YSH-05 is a mixed mode corrosion inhibitor mainly repressing negative pole process and JAY-01 is a negative pole mode corrosion inhibitor.The adsorption of YSH-05 and JAY-01 fits Bockris-Swinkels adsorption isotherm on the iron and steel surface,and corrosion inhibitor molecules form protective layers on the surface of N80 steel,which can restrain acidic component erodes N80 steel.

Key words: acidizing corrosion inhibitor, Mannich base, quaternary ammonium salt, comparative study, adsorption isotherms
