Reactivity AlertsHighly Flammable
Reactivity Profile
1,4-PENTADIENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release gaseous hydrogen. Can undergo exothermic polymerization reactions in the presence of various catalysts (such as acids) or initiators. May undergo autoxidation upon exposure to the air to form explosive peroxides. Violent explosions have occurred at low temperatures in ammonia synthesis gas units. These explosions have been traced to the decomposition of addition products between dienes such as this one and oxides of nitrogen [Bretherick, 1995].
