Halogen engineering of 4-aminoantipyrine amide derivatives for the corrosion protection of mild steel: experimental and DFT insights

Adil Afaq, Muhammad Aamir, Shahid Aziz, Simon Woodward, Muhammad Haroon, Zaroon Sajid, Hamad F. Alharbi, Nabeel H. Alharthi, Qamar Wali

Twelve halogenated 4-aminoantipyrine amides inhibit mild steel corrosion in 1 M HCl (up to 96% inhibition efficiency at 1 mM) through predominantly physisorbed Langmuir films; halogen type, position and chain length tune their performance.
