Synthesis and Performance of an Enhanced Double Mannich Acidification Corrosion Inhibitor
摘 要
以乙二胺、多聚甲醛和苯乙酮为原料经曼尼希反应合成了乙二胺双曼尼希碱盐酸盐,并合成了2-苯甲酰基-3-羟基-1-丙烯(BAA)和3-羟基苯丙酮,使用核磁共振氢谱分别对其结构进行了表征。三者复配得到增强型酸化缓蚀剂,采用静态失重法,电化学方法和SEM观察等研究了复配缓蚀剂在15% HCl溶液中对N80钢的缓蚀性能。结果表明:在90℃、15% HCl溶液中加入0.1%复配缓蚀剂,N80钢片的腐蚀速率为2.316 2 g·m-2·h-1,即达到一级标准(SY/T 5405-1996)。此外,该缓蚀剂是一种混合型缓蚀剂,在N80钢片表面的吸附作用符合Langmuir等温吸附规律。表面分析试验(SEM和EDS)验证了缓蚀剂分子在N80钢片表面形成了一层保护膜。
Abstract
Ethylenediamine double Mannich base hydrochloride was synthesized from ethylenediamine, paraformaldehyde and acetophenone by Mannich reaction. 2-(hydroxymethyl)-1-phenylprop-2-en-1-one (BAA) and 3-Hydroxypropiophenone were prepared. The structures of above three corrosion inhibitors were characterized by NMR hydrogen spectroscopy, and an enhanced acidified corrosion inhibitor was obtained by compounding these inhibitors. Static weightlessness method, electrochemical method and SEM observation were used to study the inhibition performance of the compound inhibitor on N80 steel in 15% HCl solution. The results showed that the addition of 0.1% compound corrosion inhibitor to 90 ℃, 15% HCl solution, the corrosion rate of N80 steel sheet was 2.316 2 g·m-2·h-1, which reacheed the first-level standard (SY/T 5405-1996). In addition, the inhibitor was a mixed inhibitor, and its adsorption on the surface of N80 steel sheet conformed to the law of Langmuir isotherm adsorption. Surface analysis experiments (SEM and EDS) verified that the corrosion inhibitor molecules formed a protective film on the surface of the N80 steel sheet.
