Investigating the effect of copper(II) coordination compound withCarbonylbis(azanediyl)dibenzoic acid ligand on the phase-stabilization ofammonium nitrate

In this work, a novel copper(II) coordination compound is synthesized usingCarbonylbis(azanediyl)dibenzoic acid (CAD) as ligand (Cu(II)-CAD). The structural, andmorphological property of the synthesized material are investigated using FT-IR, CHN, FE-SEM,BET and PXRD analyses. Evaluation of the obtained results indicates that CAD coordinated tocopper ions. Ammonium nitrate (AN) is an affordable oxidant, which is widely used in gasgenerators. Since AN shows crystal structure transformation in ambience temperatureaccompanied by a change in volume, its application is limited without phase stabilization [۱-۵].For phase stabilization of AN, AN/Cu(II)-CAD composite is prepared and its phase transitions isstudied using differential scanning calorimetry (DSC). The results indicate that ANIV↔ANIIIphase transition can be eliminated by hydrogen bonding between AN and Cu(II)-CAD.
