Metals corrosion and scales deposition are two serious problems of heavy burden in most industries.

What is it about?

In the present work, four novel pyrazole derivatives were synthesized and characterized for their structures using elemental analysis and spectroscopic tools. The tested compounds were fabricated by treating 2,3- diaryloxirane-2,3-dicarbonitriles with different nitrogen nucleophiles.Both problems can be mitigated by adding special chemicals capable of being adsorbed on metallic surfaces as well as on scale growing crystal surfaces. Efficient materials should be rich in functional groups containing heteroatoms and/or p bonds for supporting their adsorbability on surfaces.

Why is it important?

In the present work, four novel pyrazole derivatives were synthesized and characterized for their structures using elemental analysis and spectroscopic tools. The tested compounds were fabricated by treating 2,3- diaryloxirane-2,3-dicarbonitriles with different nitrogen nucleophiles. The density functional theory (DFT) was then applied to explore the structural and electronic characteristics of these materials. Molecular dynamics simulation was also run to scrutinize the ability of the prepared compounds to act as corrosion inhibitors and antiscalant agents by adsorbing on Fe and CaSO4 surfaces.
