摘      要：Rapid destruction of stockpiles of sarin and other chemical weapon agents(CWA)requires understanding and quantitative description of the relevant chemical *** reactions at elevated temperatures are of particular interest for prompt agent defeat *** methylphosphonate(DIMP)is a sarin surrogate particularly well suited to model sarin thermal decomposition and is often used in *** article is a review of different experimental methods addressing decomposition of gasified DIMP,respective results and their *** early decomposition products are propene,methylphosphonic acid,methyl(oxo)phosphoniumolate,and *** computational work using available kinetic data for fluorine and the phosphorus-fluorine bond predicted the decomposition under incineration *** using an isothermal flow reactor operated at 700-800 K were used to model DIMP decomposition as unimolecular reaction with results that were consistent with the earlier theoretical *** in dynamic environments was studied using DIMP supported on rapidly heated *** results showed different decomposition products and product sequences forming at different heating rates,suggesting the need for revised reaction ***,species quantification in such experiments is difficult because of inherent large temperature *** produced in a corona discharge was also reported to lead to rapid DIMP decomposition at low *** products were distinct from those observed at high *** tube experiments may be well suited to study decomposition of organophosphorus compounds like DIMP following their rapid heating in diverse ***,presently,only sarin surrogates other than DIMP have been investigated,and no intermediate reaction products,important for developing a validated mechanism,could be detected.
