Abstract

الملخص EN

 


The paper reports a novel approach based on time resolved pulsed Photo acoustic (PA) and TG-DTA techniques to study the thermal decomposition mechanisms of 4-Nitroimidazole(4NI) at 532 nm .


The study is based on the detection of NO2 released by these samples under different thermal zones.


The second harmonic i.e.


λ= 532 nm pulses of 7 ns width obtained from Q- switched Nd: YAG laser is employed to record the time and temperature dependent PA spectrum in a specially designed photoacoustic system.


The multistep thermal decomposition mechanisms in terms of new NO2 thermal windows which is a part of N- N bond and concerted ring breaking mechanism of HEMs, is reported .


The combination of PA and TG-DTA results open a new channel to understand the generation mechanism of free NO2 at different temperatures and leads to develop a new tool to scale the HEMs efficiency as a fuel
