Corrosion Control with Organic Inhibitors

Abstract

Inorganic inhibitors of corrosion by water are generally effective only under alkaline and oxidizing conditions. In ducing conditions, and microbiological action they afford little or no protection. There are many large scale operations in which water is used or handled under such tions and ,,,here effective corrosion control is desirable or

Comparing Chain Length Effect of Single Chain and Gemini Surfactants on Corrosion Inhibition of Steel in Acid

“…In order to prevent, control and reduce the corrosion rate of metal, different techniques have been recommended for various industries. One of the most attractive and effective methods for reducing the corrosion rate of steel, is the addition of a tiny amount of organic chemicals called corrosion inhibitors like surfactants (1)(2)(3). Surfactants have been claimed to be promising candidate as corrosion inhibitors for steel protection.…”

Experimental and Quantum Chemical Studies on the Corrosion Inhibition of Mild Steel By 2-((Thiophen-2-Ylmethylene) Amino)Benzenethio in 1M HCl

“…Corrosive media have been utilized in the activities of industries naming acid pickling, descaling and cleaning. Employing of natural organic inhibitors become the most active and cost successful process of reduce alloys corrosion (6)(7)(8). Synthetic organic molecules that have heteroatoms (such as nitrogen, sulfur or oxygen) in addition to pielectron systems were approved to exhibit excellent inhibition efficiencies (9)(10)(11).…”

Estudo De Primeiros Princípios De Derivados Da 2-Metil Imidazolina: Modelo De Inibidor De Corrosão

“…Os inibidores orgânicos, em geral, são classificados como inibidores de adsorção, pois tem como fator primordial a sua adsorção na superfície do material com o objetivo de protegê-lo da corrosão [7]. Estes inibidores normalmente promovem a formação de um quelato na superfície do metal, ocorrendo a transferência de elétrons de um composto orgânico inibidor para a superfície metálica (processo de adsorção química).…”
