【摘要】：以水合肼和肉桂醛為原料合成了一種新型Schiff堿酸化緩蝕劑(DCH),用紅外光譜法(FI-RT)、化學(xué)元素分析法和核磁共振法對其結(jié)構(gòu)進(jìn)行表征;通過靜態(tài)失重法和電化學(xué)方法考察了其在15%(質(zhì)量分?jǐn)?shù),下同)HCl中對N80鋼的緩蝕作用。結(jié)果表明:DCH是一種混合型酸化緩蝕劑,可在N80鋼表面形成保護(hù)膜,有效抑制酸液的腐蝕;當(dāng)DCH加入量為0.75%時,N80鋼的腐蝕速率為2.27g·m~(-2)·h~(-1),緩蝕率高達(dá)99.81%;DCH在N80鋼表面的吸附規(guī)律符合Langmuir吸附模型。
[Abstract]:A novel Schiff alkali-acidizing inhibitor was synthesized by using hydrazine hydrate and cinnamaldehyde as raw materials. Its structure was characterized by FTIR, chemical element analysis and nuclear magnetic resonance (NMR). The corrosion inhibition of N80 steel was investigated by static weightlessness method and electrochemical method. The results show that the w _ (%) DCH is a mixed acidizing inhibitor, which can form a protective film on the surface of N80 steel and effectively inhibit the corrosion of acid solution. When the amount of DCH was 0.75, the corrosion rate of N80 steel was 2.27 g / m ~ (-2) 路h ~ (-1) ~ (-1), and the corrosion inhibition rate was as high as 99.81%. The adsorption law of DCH on the surface of N80 steel was in accordance with the Langmuir adsorption model.
