Corrosion is a highly dangerous phenomenon that causes huge economic and safety problems. Various methods of corrosion monitoring, including cathodic protection, panting and coatings, alloying and dealloying (reduction in metal impurities), surface treatments, and use of corrosion inhibitors have been developed depending upon the nature of metal and environment. Application of organic compounds, especially heterocyclic compounds, is one of the most common, practical, easy, and economic methods of corrosion mitigations. Obviously, these compounds become effective by adsorbing on the metallic surface using electron‐rich centers including multiple bonds and polar functional groups. These electron‐rich centers act as adsorption sites during their interaction with the metallic surface. Along with acting as adsorption sites, the polar functional groups such as –OH (hydroxyl), –NH 2(amino), –OMe (methoxy), –COOH (carboxyl), –NO 2(nitro), –CN (nitrile), and so on also enhance solubility of organic compounds in polar electrolytes. Present book describes the collection of major advancements in using organic compounds as corrosion inhibitors including their synthesis, characterization, and corrosion inhibition mechanism.

Through this book it can be seen that use of organic compounds serves as one of the most effective, economic, and ease methods of corrosion monitoring. Using previously developed methods, 15% (US $375) to 35% (US $875) of cost of corrosion can be minimized. Different series of organic compounds, including heterocyclic compounds, are effectively used as corrosion inhibitors for different metals and alloys in various environments. Because of the increasing ecological awareness and strict environmental regulations, various classes of environmental‐friendly alternatives to the traditional toxic corrosion inhibitors have been developed and being implemented. These series of compounds mostly include carbohydrates, natural polymers and amino acids (AAs), and their derivatives. Corrosion scientists and engineers strongly believe that these environmental‐friendly alternatives will be capable to replace, in the near future, the toxic marketable products that are still being used via many worldwide industries.

A book covering the recent developments on using organic compounds as corrosion inhibitors is broadly overdue. It has been addressed by Drs. Verma, Hussain, and Ebenso in this book which attends to fundamental characteristics of organic corrosion inhibitors, their synthesis and characterization, chronological growths, and their industrial applications. The corrosion inhibition using organic compounds, especially heterocyclic compounds, is broad ranging. This book is divided into five sections, where each section contains several chapters. Section 1 “Basics of corrosion and prevention” describes the basic of corrosion, experimental and computational testing of corrosion, and a comparison between organic and inorganic corrosion inhibitors. Section 2 “Heterocyclic and non‐heterocyclic corrosion inhibitors” describes the collection of different series of heterocyclic and non‐heterocyclic corrosion inhibitors such as amines, imidazole, quinoline, pyridine, indole, and their derivatives. This section also includes organic compounds as corrosion inhibitors for oil and gas industries.

Section 3 “Organic green corrosion inhibitors” entirely focuses on green corrosion inhibitors. This section describes the corrosion inhibition characteristics of carbohydrates, amino acids (AAs), oleochemicals, chemical medicines, ionic liquids (ILs), and their derivatives. Section 4 “Organic compounds based nanomaterials as corrosion inhibitors” describes the corrosion inhibition properties of carbon nanotubes (CNTs: SWCNTs and MWCNTs), graphene oxide (GO), and their composites. In the end, Section 5 “Organic polymers as corrosion inhibitors” gives a description on natural and synthetic polymers as corrosion inhibitors.

Overall, this book is written for scholars in academia and industry, working corrosion engineering, materials science students, and applied chemistry. The editors and contributors are well‐known researchers, scientists, and true professionals from academia and industry.
