Corrosion inhibition, adsorption and thermodynamic properties of hydrophobic-tailed imines on carbon steel in hydrochloric acid solution: a comparative study

Three hydrophobic-tailed imine compounds containing linear alkyl, branched alkyl and phenyl groups adjacent to the imine bond namely N-propylidenehexadecanehydrazide (PHH-L), N'-(2,2-dimethylpropylidene)hexadecanehydrazide (DMPHH-B) and N-phenylpropionalidene hexadecanehydrazide (PPHH-A), respe...
