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.

Metals play a pivotal role in industry; their use constantly grows. It is virtually impossible to find an industrial field without the use of metals and their alloys. However, owing to the quality degradation of metal during the operational process, corrosion appears not only on its surface but also under a coating, which leads to its destruction. To avoid this, corrosion inhibitors are necessary. Organic compounds have been widely used as corrosion inhibitors. Many organic corrosion inhibitors have been developed nowadays. In the literature, organic compounds comprising N, O, S and P heteroatoms are described, which reduce corrosion rate. The organic compounds are adsorbed on the metal surface, forming a thin layer. Adsorption occurs either through electrostatic interaction or, in some cases, the formation of covalent bonds. The work aimed to study isothiuronic salts as corrosion inhibitors to evaluate their protective properties using the polarisation curves method. Objects of research were isothiuronic compounds containing two active centres separated by saturated and unsaturated carbon bonds (structures 1-3). In structures 4-7, one isothiuronic fragment has different propylene substituting groups. It has been previously shown that these compounds can act as effective brightening agents when applying nickel coatings. A model solution with a density of 1.12 g/cm3 was prepared to study the corrosion inhibitors. The corrosion inhibitor concentration was 400 mg/L. Studies have shown that the compounds with two isothiuronic moieties do not always exhibit improved properties for inhibiting metal degradation in a corrosive environment. In particular, they showed worsening of the inhibiting properties for samples made of steel 20 and identical properties for that made of steel 3.
