Schiff bases are important in corrosion inhibition due to their ability to form stable complexes with metal ions and create protective layers on metal surfaces, thereby extending the lifespan of structural materials in various industrial applications. In this study the Salicylideneaniline and its derivatives were analyzed as corrosion inhibitor versus mild steel corrosion via DFT analysis. The eight molecules were chosen; salicylideneaniline, 2-(benzylideneamino)phenol, 4-(benzylideneamino)phenol, 2-phenyldiazenylphenol, 2-Phenylazo-4-methylphenol, 3-methyl-2-phenyldiazenyl phenol, 2-[(2-methylphenyl)diazenyl]phenol, 4-phenyldiazenylbenzene-1,3-diol), for this purpose. The Gaussian 03 program and the 6-311++G (d, p) basis set was used. Electronic properties such as the energy of the highest occupied molecular orbital (EHOMO), energy of the lowest unoccupied molecular orbital (ELUMO), energy gap (∆E) between LUMO and HOMO, dipole moment, and charges on the backbone atoms, ESP were determined.
Schiff bazları, metal iyonları ile stabil kompleksler oluşturma yetenekleri ve metal yüzeylerinde koruyucu tabakalar oluşturma kapasiteleri sayesinde, çeşitli endüstriyel uygulamalarda yapısal malzemelerin ömrünü uzatmada korozyon inhibisyonunda önemlidirler. Bu çalışmada, Salisilidenanilin ve türevleri, DFT analizi yoluyla yumuşak çelik korozyon inhibitörü olarak incelendi. Bu amaçla salisilidenanilin, (2-(benzilidenamino)fenol, 4-(benzilidenamino)fenol, 2-fenildiazanilfenol, 2-fenilazo-4-metilfenol, 3-metil-2-fenildiazanilfenol, 2-[(2-metilfenil)diazenil]fenol, 4-fenildiazanilbenzen-1,3-diol) sekiz molekül seçildi. Gaussian 03 programı ve 6-311++G(d,p) temel seti kullanıldı. En yüksek dolu moleküler orbital enerjisi (EHOMO), en düşük dolu olmayan moleküler orbital enerjisi (ELUMO), LUMO ve HOMO arasındaki enerji farkı (∆E), dipol momenti ve atomları üzerindeki yükler gibi elektronik özellikler ve ESP belirlendi.
