Abstract
The mechanism of decomposition of diallyl has been studied in a static system in the temperature range 460–520 °C. The principal gaseous products (room temperature) were propylene, methane, ethylene, and 1-butene, and the liquid products were cyclopentene, cyclopentadiene, 1-hexene, and benzene. The over-all activation energy of decomposition was 31.3 ± 1.0 kcal/mole for an A factor of 107 sec−1. A mechanism of decomposition based on hydrogen abstraction by allyl and the addition of allyl to olefinic double bonds is proposed. Some decomposition by a non-radical mechanism may also occur.Keywords
