The Department of Chemical Engineering at the University of Technology discussed the master’s thesis titled.

Synthesis and Characterization of New Heterocyclic Compounds Containing Oxazolidine Ring as Corrosion Inhibitors for Mild Steel in Acidic Solution

Thursday, 11/2/2023

The student Zeina Ibrahim Jassim’s thesis aimed to synthesize and distinguish heterocyclic organic compounds that possess a thion ring, one of the oxazoladine derivatives, through the synthesis of the compound known as Z1. Later, the compound was synthesized.

4 amino-benzoic hydrazide 5(4-amino phenyl) 1,3,4 oxadiazole – 2thiol

Known as Z2. Then, the known inhibitors (DMOT, DHOT) are prepared, and then the inhibitors that have been synthesized are diagnosed using modern techniques such as nuclear magnetic resonance spectroscopy, a melting point device for the compounds. In addition to evaluating the efficiency of the inhibitors that were synthesized on a model of mild steel to calculate corrosion resistance in one molar HCl acidic medium using the weight loss method. Conditions were used to choose the lowest corrosion rate from the results of the weight loss data. The results showed that the corrosion rate in the absence of the inhibitor increases with increasing temperature, and the change in the corrosion rate with temperature is based on the Arrhenius equation and the activation energy of the reaction was activated. Where work was obtained that shows the extent of the corrosion rate and its relationship to different temperatures and varying concentrations of inhibitors.

The discussion committee consisted of Prof. Dr. Jamal Mana Ali as Chairman, with the membership of Assistant Prof. Dr. Sarmad Talib Najm from Al-Nahrain University and Assistant Prof. Bashir Ahmed Abdel Hussein

Under the supervision of Prof. Dr. Khaled Hamid Rashid and Prof. Dr. Khaleda Farhan Al-Azzawi.
