摘要

•The studied crystalline compounds is an excellent corrosion inhibitor for mild steel in 1.0 M HCl medium.•7 M shows higher inhibition efficiencies with inhibition efficiency for EIS (93.7%) techniques at 150 ppm.•The inhibitors suggests that all investigated compounds are physically absorbed onto steel surface.
