The oxidation of di-iso-propyl-ether (DIPE) was studied in a jet-stirred reactor. Fuel-lean, stoichiometric, and fuel-rich mixtures (equivalence ratios from 0.5 to 4) were oxidized at a constant fuel mole fraction of 1000 ppm, at temperatures ranging from 500 to 1160 K, at 10 atm, and constant residence time of 0.7 s. The chosen conditions are consistent with our previous studies on ether oxidation. Mole fraction profiles were obtained through sonic probe sampling, and analyzed by gas chromatography and Fourier transform infrared spectrometry.
As opposed to our previous studies on ethers, DIPE showed no low temperature reactivity. The present data and literature experiments were simulated with our ether oxidation mechanism showing good agreement.
