Abstract
The isomerization of 2-methyl-4,5-dihydrofuran was studied behind reflected shock waves in a pressurixed driver single-pulse shock tube over the temperature range 805-1030 K and densities of approximately ∼3×10 -5 mol/cm 3 . Two isomerization products, acetylcyclopropane and 3-penten-2-one, are obtained in the isomerization. Acetylcyclopropane is formed in an irreversible process from 2-methyl-4,5-dihydrofuran. It further isomerizes, at higher temperatures, to cis- and trans-3-penten-2-one. At high temperatures where the conversion of 2-methyl-4,5-dihydrofuran is high, the main source for 3-penten-2-one is acetylcyclopropane. At lower temperatures 3-penten-2-one is formed mainly by a direct isomerization of 2-methyl-4,5-dihydrofuran
