Novel Bis Maleimide Derivatives Containing Azo Group: Synthesis, Corrosion Inhibition, and Theoretical Study

Novel derivatives of heterocyclic azo compounds have been synthesized through a free catalyst reaction. The structures of the synthesized compounds were confirmed by using different techniques such as 1H-NMR, 13C-NMR, and mass spectroscopy. The prepared derivatives were evaluated as corrosion inhibi...

Novel Bis Maleimide Derivatives Containing Azo Group: Synthesis, Corrosion Inhibition, and Theoretical Study

The structures of the synthesized compounds were confirmed by using different techniques such as 1H-NMR, 13C-NMR, and mass spectroscopy. The prepared derivatives were evaluated as corrosion inhibitors for mild steel after the inhibitory performance toward mild steel in 0.1 M HCl solution. The prepared derivatives, i.e. (1,1'-(((1E,1'E)-1,4-Phenylenebis(diazene-2,1-diyl))bis(4-methyl-3,1-phenylene))bis(1H-pyrrole-2, 5-dione)) 1 and (1,1'-(((1Z,1'Z)-(Oxybis(4,1-phenylene))bis(diazene-2,1-diyl)) bis(4-methyl-3,1-phenylene))bis(1H-pyrrole-2,5-dione)) 2 showed inhibition efficiency 89.22% and 91.30%, respectively at concentration 1 × 10–3 M.
