Abstract
The detonation of mixtures of ethylene oxide, oxygen, and argon has be en studied in a shock tube and also using computer modeling from 950 t o 1220 K at 100 torr. The emission from OH at 306.4 nm from behind the reflected shock was measured to monitor ignition delay times. Using a mechanism of 88 elementary reactions, involving 30 chemical species, ignition delay times were computed. The simulation and sensitivity ana lysis confirmed that the isomerization of ethylene oxide to acetaldehy de is the main chain-initiation step.
