Pyrazoline derivatives as possible corrosion inhibitors for mild steel.

What is it about?

Various experimental and theoretical methods have been employed to study the effectiveness of two pyrazoline derivatives namely, 2-(4-(5-(p-tolyl)-4,5-dihydro-1H-pyrazol-3-yl)phenoxy)acetic acid (P1) and 2-(4-(5-(4-nitrophenyl)-4,5-dihydro-1H-pyrazol-3-yl)phenoxy)acetic acid (P2) as corrosion inhibitors for mild steel in 1.0 M HCl at 303 K.

Why is it important?

Synthesis and screening of newer organic compounds are important for variety of applications like in the field of medicinal chemistry, as corrosion inhibitors or in material science. Many of the molecules when tested in the medicinal field turns to be of no potential which could be explored for other properties. We explore several such compounds in the field of corrosion science.

There are significant interest in the protection of metals against corrosion. Among many methods available to solve this problem, addition of inhibitors is one of the choice especially when the metal is exposed for large quantity of electrolyte medium. This paper explores the potential of the compounds synthesized for such applications. These compounds are synthetically scalable and chemically stable. These data presented may be useful for the practitioners of corrosion studies.
