Case Study

Imidazolidine and Sodium Lauryl Polyoxyethylene Ether Sulfate Synergistically Inhibit Corrosion of Q235 Steel in H2SO4 Solution

Li S, et al. Corrosion Science, 2024, 236, 112260.

Imidazolidine (IM) has demonstrated significant efficacy in corrosion inhibition, particularly when combined with sodium lauryl polyoxyethylene ether sulfate (SLPES) for protecting Q235 steel in sulfuric acid (H2SO4) solutions. The synergistic interaction between IM and SLPES results in a substantial enhancement of inhibition efficiency, reaching up to 94.5%. This dual-inhibitor system is capable of suppressing both cathodic and anodic reactions more effectively than when either IM or SLPES is used individually. The formation of a dense inhibition film on the steel surface, primarily facilitated by co-adsorption of both inhibitors, significantly reduces corrosion rates. Structural analyses via scanning electron microscopy (SEM), atomic force microscopy (AFM), and confocal laser scanning microscopy (CLSM) show that the steel surface treated with IM/SLPES remains nearly uncorroded and exhibits a smooth, protective coating. Additionally, theoretical calculations further corroborate the experimental findings, indicating enhanced physisorption and chemisorption of the inhibitor molecules when IM is compounded with SLPES. These results highlight the functional role of IM in corrosion inhibition, particularly in acidic environments, and its potential application in the development of efficient corrosion inhibitors for industrial metal protection.

Imidazolidine as a Reactant in Grignard Reagent-Mediated Ring-Opening Reactions for the Synthesis of Tertiary Amines

Comparini L. M, et al. The Journal of Organic Chemistry, 2024.

Imidazolidine is utilized in a novel synthetic methodology involving its ring-opening reaction with Grignard and cuprate reagents, leading to the formation of secondary sulfonamides with diversely substituted tertiary amines in the β- or γ-position. This reaction, which proceeds without undesired side reactions commonly observed in similar sp3-organometallic multicomponent Mannich-type reactions, highlights the effectiveness of sulfonamide protection of the nitrogen atom during both the formation of the cyclic aminal and the ring-opening process. The mechanism, supported by computational density functional theory (DFT) analysis, suggests the formation of an iminium ion intermediate, where the Lewis acidity of the organometallic reagent induces the ring-opening by coordination. This method provides a robust pathway for the nucleophilic functionalization of diamines, including those with adjacent chiral centers, a task that would be difficult to achieve using conventional synthetic routes. Thus, imidazolidine plays a crucial role in the development of a versatile synthetic tool for creating complex amine derivatives.
