The public discussion of the master’s student (Hanan Eltaif Yassin) from the Department of Chemistry - College of Science - University of Anbar was held on Sunday, 5-9-2021 at Jaber Bin Hayyan Hall in the College of Science about her thesis tagged:-

((Synthesis and diagnosis new heterocyclic organic compounds of various rings of ribs and the study of thermal stability))

Aimed to synthesize and characterize new heterocyclic Compounds using new methods and study their thermal stability as a step for future work.

The results showed obtaining of four heterocyclic Compounds with all of these Compounds are charted using FT-IR 1H 13CNMR and TGA The Thermal stability.

The cyclic heptagons were characterized using (FT-IR, 1H-NMR, 13C-NMR, CHN, and TGA). And similarly produced heterocyclic rings with sides 8, 10, and 11, with the addition of 1,3-diamino propane and 1,5-diamino pentane, and 1,6 diamino hexane Consecutively.
