Sarin simulant combustion at high temperature: Time resolved laser absorption spectroscopy of intermediate products in a shock tube

摘要

Due to high toxicity of chemical warfare (CW) agents such as sarin - GB, experiments to study their incineration are carried out using organo phosphorous simulants. The simulants have similar chemical structures and combustion rates as that of CW agents, and knowledge on their decomposition kinetics can be used to predict combustion of CW agents. There are major gaps in our knowledge of the high temperature decomposition pathways leading to final products and combustion chemistry of CW agents and simulants that are crucial to characterize their burning process, which will help to design better strategies to counter weapons of mass destruction. Hence, pyrolysis of an organo phosphorous simulant - tri-ethyl phosphate (TEP) were carried out using shock tube and laser absorption spectroscopy at 4580.4 nm to measure intermediate CO time histories.
