Density functional theory study of the corrosion inhibition performance of 6-mercaptopurine and 6-thioguanine expired drugs toward the aluminium (111) surface

Abstract

The efficiency of 6-mercaptopurine and 6-thioguanine expired drugs as corrosion inhibitors of aluminium surface was thoroughly assessed using DFT method.

Synthesis of a resorcinol-based derivative as a corrosion inhibitor for low-carbon steel in 0.5 mol L−1 HCl medium: chemical, electrochemical, and theoretical aspects

“… 56 According to the literature, the effective nucleophile and electrophile have lower and greater values of ω , respectively. 57 The more prominent nucleophilic character of the DMIH molecule is indicated by the reported ω value (0.092) in Table 8 . For the DMIH compound, the computed Δ N max is 1.385.…”

An examination of the effectiveness of the expired drug isoprinosine in preventing aluminum corrosion in alkaline solutions using both computational and experimental techniques

“…These medications include a variety of organic chemicals that can be utilized as anti-corrosion agents to lessen metal dissolution. 21–44 One of the common drugs used to treat herpes is isoprinosine. It is possible to reuse isoprinosine, which is not sold, as an inhibitor for metal corrosion.…”
