Research Progress on Types and Mechanism of Common Organic Corrosion Inhibitors

In this paper, several kinds of common organic corrosion inhibitors, such as heterocyclic, aldehydes and ketones, organic phosphonic acid, are introduced. The development prospects and application limitations of some corrosion inhibitors are discussed and pointed out. There are also studies have shown that usually two or more corrosion inhibitors are combined or better than a single corrosion inhibitor. Taking the effect as the introduction point, the mechanism of action of organic corrosion inhibitors is generally recognized. Finally, the future research direction of organic corrosion inhibitors is prospected.
