Protection of mild steel corrosion by three new quinazoline derivatives: experimental and DFT studies

Key Points

• Corrosion protection is enhanced through three new quinazoline derivatives, showing significant efficacy in reducing mild steel corrosion.
• The electrochemical analysis indicates that the best derivative reduces corrosion rate by 60% compared to untreated mild steel.
• Density functional theory (DFT) studies provide insight into the molecular interactions that enhance corrosion protection mechanisms.
• These findings support the potential application of quinazoline derivatives in industrial settings to protect mild steel from corrosion.
