The decomposition kinetics of 2-ethylhexyl nitrate behind incident shock waves in a diaphragmless shock tube facility were studied with a laser schlieren densitometry diagnostic at temperatures from 670 to 940 K and pressures of 35, 59, and 118 Torr. Measured density gradients informed improvements to the decomposition mechanism of 2-ethylhexyl nitrate. In particular, the analysis revealed important 3-heptyl radical chemistry. The measured and predicted rate constants are near the high-pressure limit.
