Corrosion of metal prevention using chalcone molecules..

What is it about?

The effect of three chalcone derivatives namely, (E)-ethyl 2-(4-(3-(4-fluorophenyl)acryloyl)phenoxy)acetate (AE-1), (E)-ethyl 2-(4-(3-(3,4-dichlorophenyl)acryloyl)phenoxy)acetate (AE-2) and (E)-ethyl 2-(4-(3-(2,5-dimethoxyphenyl)acryloyl)phenoxy)acetate (AE-3) on the mild steel (MS) corrosion in 1.0 M HCl at 303 K has been investigated. Note: This paper has already been cited by 65 times (including few by us) !

Why is it important?

Simple compounds and novel properties.....!!

Chalcones can be a green corrosion inhibitor. we are currently working on many more such derivatives. Corrosion inhibition by organic compounds are one of the active research area around the world. A glance of the literature show that almost any compound with heteroatom could be having some potential as inhibitor. However, researchers less focus on cost of such compounds limiting their practical applications, if any. In this context chalcones will be of interest as they are cheap and easily scalable.
