Development and testing of organic inhibitors for industrial cleaning applications

摘要

This article discusses the effectiveness of three new organic inhibitors -1-cinnamaldehyde thiosemicarbazone (CTS), 1-benzaldehyde thiosemicarbazone (BTS), and 2-4, dicinnamyldene aminophenylene (DCAP)- in controlling the corrosion of carbon steel in hydrochloric acid (HCI) solution at 60℃. CTS, BTS, and DCAP were compared with a standard commercial corrosion inhibitor. Laboratory tests revealed that corrosion protection values of the synthesized compounds were higher than those of the commerical inhibitor.
