The Mechanism and Dynamics of Explosive Combustion in Aerosol Fuels
Abstract
This project investigates the explosive combustion of aerosol fuels using a single particle mass spectrometer. Initiating explosive reactions of small samples (tilde 10 to the -12 grams) in vacuum allows the intermediate products of the reaction to escape into a collisionless region where we detect them using laser spectroscopy. Recent results from our laboratory explore the mechanism of amine sensitization in nitromethane. We initiate the decomposition of nitromethane/diethylamine aerosols using a CO2 laser and observe the -intermediates of the react ion using vacuum-ultraviolet ionization coupled with time-of-flight mass spectroscopy. We find that reactions of the aci-anion of nitromethane, formed in an acid-base equilibrium with the amine% are critical in the sensitization mechanism.
