Inhibitors are routinely employed in chemical cleaning solvents used for removing scale from electrical power plants and industrial equipment since these cleaning solvents are corrosive to metal surfaces. This paper discusses the development of three new inhibitors developed for the use in hydrochloric acid, ammoniated EDTA or citric acid chemical cleaning solutions. Synthesis procedures used in the production of Mannich derivatives employed in the inhibitors were optimized for maximum corrosion resistance and reduced toxicity. All auxiliary ingredients used in the formulation of final inhibitor products were chosen to give the lowest possible toxicity of these products.
