Scientific Article

The lecturer in the College of Education for Pure Sciences / Department of Chemistry, Dr. (Shatha Abdul-Amir Jawad), obtained an approval to publish a scientific article titled (Azo compounds – Schiff … their composition and applications) by the Scientific Articles Committee at the Presidency of the University of Karbala after the article fulfilled all publishing conditions. (Prof. Dr. Shatha Abdel-Amir Jawad) stated that compounds that contain both azo and imine groups are called azoimine compounds or azo-shift bases that are prepared from the raw material, such as azo aldehydes and primary amines, through a catalytic condensation reaction. It highlights the various important biological activities seen in compounds containing azo bonds and azomethine.
Azo compounds are known by the appearance of an azo group -N=N- which is linked to two carbon atoms of SP2 hybridization that belong to aliphatic or aromatic groups, which are often part of the extension of the off-site electron system, which includes aromatic rings, called chromophores, and this gives them stability and stability high due to the resonance phenomenon. Most azo compounds contain one azo group, but some contain two, three, or more of these groups.
While aliphatic azo compounds with the formula R1-N=N-R2 (when both R1 and R2 are alkyl groups or one of them) are unstable. By means of heat or radiation, the two bonds of nitrogen – carbon (C-N) will be simultaneously broken, which leads to the liberation of nitrogen gas N2 and be concentrated for free radicals. Because of this, some aliphatic azo compounds are considered as initiators of free radicals.
