On the protective action of 1,2,3-benzotriazole derivative films against copper corrosion

Surface-enhanced Raman scattering (SERS) of benzotriazole derivative corrosion inhibitor prepared in aqueous media

“…21,22 On the other hand, alkyl groups in the benzene ring exhibit higher inhibiting efficiency than that obtained for BTAH. 21,23 However, substitution in the triazole ring does not always decrease the inhibiting efficiency. The BTAH derivative 1-[N,N]-bis-(hydroxyethyl)aminomethyl-benzotriazole (BTLY) has exhibited better inhibition than BTAH at low concentration and low pH levels, whereas at high pH its inhibiting efficiency was lower than that of BTAH.…”

Alkyl-benzotriazole derivatives as inhibitors of iron and copper corrosion

“…In both cases, the presence of a sufficiently long alkyl chain improves the inhibiting action of the base molecule because the van der Waals interactions among the long aliphatic chains can enhance the formation of a thicker, more compact, less defective, more hydrophobic and therefore more protective inhibitor layer [30,[34][35][36]. These positive effects are the greater the longer the chain, at least up to 6 carbon atoms.…”

The thiazole and triazole derivatives as inhibitors of metal corrosion: Part II

“…Analiza rezultata kompjuterskih simulacija zasnovanih na teoriji funkcionala gustine (DFT) ukazuje na znatno jače vezivanje deprotonovane forme benzotriazola za površinu bakra koja stoga predstavlja stvarnu aktivnu vrstu za inhibiciju korozije [11]. Ovaj rezultat je i eksperimentalno potvrđen, pošto benzotriazol ispoljava najmanju efikasnost u kiselim rastvorima [12,13], u kojima je i količina deprotonovanog oblika najmanja. U cilju pronalaženja moguć-nosti povećanja inhibitorske efikasnosti BTA u kiseloj sredini u odnosu na koroziju bakra ispitan je uticaj različitih supstituentskih grupa na inhibitorsko dejstvo osnovnog molekula benzotriazola kao sinergetsko dejstvo različitih dodataka.…”
