Synthesis, Characterization, and Theoretical Investigation of the Effectiveness as Anti-corrosion for Chalcone Derivatives

In this research, the focus was on preparing a number of chalcone derivatives using the Claisen-Schmidt reaction method through the reaction of some benzaldehyde derivatives with acetophenone substitutes in the presence of a basic medium represented by (NaOH) at a concentration of 10%. The benzaldehyde derivatives and acetophenone derivatives were also dissolved in ethanol at a concentration of 98%. Before starting the preparation, a number of chalcone derivatives were banned, which were prepared and referred to as [Ch1, Ch2,Ch3, Ch4, Ch5]. The substitutes that were used in the preparation were 4-chlorobenzaldehyde, 4-aminoacetophenone, benzaldehyde, 3-Nitroacetophenone, 4-Nitrobenzaldehyde. Acetophenone ,2-4-dichlorobenzaldehyde, and 4-(dimethylamino)benzaldehyde. The compounds were spectroscopically studied using FT-IR , 1H-NMR ,13C NMR, and UV-Vis spectroscopy After that, the theoretical studies of the prepared compounds as corrosion inhibitors were conducted. They were studied theoretically using the Gaussian is a general purpose computational chemistry software package. Chalconate derivatives have the capacity to serve as electron donors as anti-corrosion agents. and it was found that derivative Ch5 is more effective theoretically as a corrosion inhibitor
