Many (but not all) of the experimental results obtained in JSR are symbolized in Figures 4-6, and all experimental measurements are summarized in the Supporting Information
in tabular form. These figures show that 2-methyl-2-butene starts to react at about 700 K, with little reactivity observed at lower temperatures.
Overall, there are few sources of experimental data to aid in the development and testing of kinetic mechanisms for C5 and larger olefinic fuels. It is also surprising that no past experiments or kinetic modeling papers have provided any intermediate species measurements for branched unsaturated hydrocarbon fuels larger than isobutene. Current Experiments and Kinetics
Therefore, the reaction mechanism is rather unique, and we hope to follow this work with similar studies for other branched, unsaturated pentenes and hexenes.
2-Methyl-2-butene technology. The 90% remainder is mainly 2-methyl-1-butene.
Effect of equivalence ratio on the ignition delay time of 2-methyl-2-butene in 99% Ar The experiments were carried out at a constant pressure of 1.06 bar (800 Torr), with a residence time of 1.5 ± 0.1s and a temperature range from 600 –1100 K, and stoichiometric conditions. Some experiments were performed at temperatures as low as 500 K, but little reactivity was observed below 700 K. Helium was used as the diluent and the study was performed at a fuel mole fraction of 0.01. 2-Methyl-2-butene, helium, and oxygen were supplied by Sigma-Aldrich (≥99.0% purity) and Messer (99.999% purity for He, 99.995% purity for O2).
Two experimental studies were carried out on the oxidation of 2-methyl-2-butene, one measuring the ignition delay time after a reflected shock wave in a stainless steel shock tube and the other measuring the fuel, intermediate and product species mole fraction. Jet Stirred Reactor (JSR).
2-Methyl-2-butene is a clear, colorless liquid with a petroleum-like odor. Density is less than water, insoluble in water. So float on the water. Vapor is heavier than air.
