Treatment with N-Methyl-Ethanolamine or Mono-Ethanolamine for Phase 3 of the Explosive Destruction System M79 Bomb: Phosgene Treatment and Evaluation
Abstract
The effectiveness of two chemical reagents, mono ethanolamine (MEA) and N-methyl ethylamine (NMEA), to neutralize phosgene (CG) and reduce its residual concentrations to acceptable levels (<50 ppm) and under, to the extent possible, was researched. This study mimicked Explosive Destruction System (EDS) processes to determine the reaction products for each reagent down to 0.05 wt% (500 ppm) of the respective reaction masses. The quantity and identity of precipitated solids generated from the respective reactions were determined, and reaction headspace gases were identified and quantified. The heat of reaction for the neutralization reaction for each reagent with CG was also determined. Reaction conditions of temperature and mixing speed as well as the pressure generated during the reaction between the respective reagents and CG, including at the reaction terminus, were measured. After the reaction was complete, the bulk neutralents produced from the reactions were characterized and reported by measurement of the viscosity, pH, density, Resource Conservation and Recovery Act (RCRA) components (volatile organic compounds [VOCs], semi-VOCs [SVOCs], metals, reactivity), and corrosivity of the respective matrices. Finally, the neutralent that best met the success parameters outlined by the Recovered Chemical Materiel Directorate was determined.
