Abstract

Corrosion inhibition of synthesized eugenol acetate (EA), eugenol benzoate (EB), 3-allylanisol (AA) and dihydroeugenol (DHE), and commercially available eugenol (E), guaiacol (G) and safrole (S) on mild steel metal specimens investigated in 0.10 mol dm^–3 NaCl solutions with the inhibitor concentrations of 100 and 200 ppm using mass loss measurements and electrochemical methods indicate that all the above compounds show corrosion inhibitory properties in the decreasing order of EB > EA > E > DHE > G > S > AA. The above model compounds function as mixed-type inhibitors, and the effectiveness of the functional groups of eugenol on the inhibition of mild steel corrosion in salty medium can be ordered as, phenyl group, –OH group, –OCH₃ group and allyl group in decreasing order of efficiency.

摘要

合成的丁香酚丁香酚（EA），丁香酚丁香酚（EB），3-烯丙醇（AA）和二氢丁香酚（DHE）以及市售丁香酚（E），愈创木酚（G）和黄樟醇（S）对低碳钢金属样品的腐蚀抑制作用在0.10摩尔分米研究^-3用质量损失的测量和电化学方法100和200ppm的抑制剂浓度的NaCl溶液表明，所有上述化合物显示在EB> EA> E> DHE“G>降序腐蚀抑制性质S> AA。上述模型化合物起着混合型抑制剂的作用，丁香酚的官能团对抑制咸介质中的低碳钢腐蚀的有效性可按以下顺序排列：苯基，-OH基团，-OCH ₃ 基和烯丙基的降序排列。
