In this chapter, the authors present a synthesis of some works carried out within the framework of the study of the corrosion inhibiting activity of a set of monosaccharide derivatives as new biodegradable, nontoxic corrosion inhibitors, and respectful of the environment. The comparative study that they present reveals the existence of more than 20 compounds derivatives of monosaccharide used as corrosion inhibitors in neutral and acidic mediums, and which have given rise to very good corrosion inhibiting efficiencies. These studies of the corrosion inhibiting effect were studied using potentiodynamic polarization curves and electrochemical impedance spectroscopy methods.

The review of methods of industrial equipment corrosion prevention is presented. Application of technological means using chemical reagents and surface-active substances is considered, namely dehydration and desalting of hydrocarbon products of deposits by surface-active substances – so called demulsifiers. Corrosion inhibitors and neutralizing agents for protection of condensation-refrigeration equipment and overheads of atmospheric columns are examined. The amount of reagents to be used and the process conditions were determined.

AbstractIn this work, the O,O’-dithiophosphate derivatives of S-4-methylbenzyl-O,O’-di(phenyl) dithiophosphate (Inhi-Ph) and S-4-methyl benzyl-O,O’-di(4-bromophenyl) dithiophosphate (Inhi-BrPh) were synthesized and characterized by elemental analysis, FT-IR, 1H, 13C and 31P NMR. Meanwhile, the corrosion inhibition of Q235 steel in HCl solution by synthesized inhibitors was evaluated by weight loss and electrochemical measurements. Measurement results indicate that the two inhibitors of Inhi-Ph and Inhi-BrPh are mixed-type inhibitor, the inhibition efficiency increase with inhibitor concentration increasing, decrease with HCl concentration and temperature increasing. The adsorption of Inhi-Ph and Inhi-BrPh on Q235 steel surface obeys Langmuir isotherm, which belongs to chemical adsorption.
