Methyl acrylate connects covalently with alkylpyridinium bromide to build N-alkyl-3-(2-methox-ycarbonyl-vinyl)pyridinium bromide (MPA-n, n = 8–14). MPA-n inhibited X70 steel from corrosion in5 M HCl with inhibition efficiency of 98% and the inhibition capacity was in the order of MPA-14 > MPA-12 > MPA-10 > MPA-8. Quantum chemical calculation unveiled that MPA-n adsorbed on iron surface byO atom in MA moiety offering electrons to d orbital of iron and by p* orbital of pyridinium acceptingelectrons from iron, and MPA-n with longer alkylchain possessed higher EHOMO, lower DE, largermolecular volume and dipole moment, all suggesting the same corrosion inhibition order as that inexperiments
