Abstract

2,3‐Dimethylbutane has been pyrolyzed in a single‐pulse shock tube. The initial steps appear to involve the breaking of carbon—carbon bonds. At about 1100°K the decomposition mechanism is as follows: [Complex chemical formula] The Arrhenius parameters for the bond‐breaking steps are

\begin{matrix} k_{1} {=10}^{16.1} \exp (−76 000/RT) \sec^{−1} \\ k_{2} {=10}^{16.6} \exp (−81 100/RT) \sec^{−1} . \end{matrix} {(1000}^{\circ} {−1200}^{\circ} K)
