| Hazard Information | Back Directory | [General Description]
A clear colorless liquid with an acrid odor. Flash point of-20°F. Boiling point 5°F. A dangerous fire risk. Vapors are irritating to the eyes and respiratory system. Subject to polymerization if heated or contaminated. If the polymerization takes place inside a container, the container may violently rupture. Insoluble in water. Used to make intermediates and polymers. | [Reactivity Profile]
1,3-PENTADIENE(504-60-9) may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions. May undergo autoxidation upon exposure to the air to form explosive peroxides. Violent explosions at low temperatures in ammonia synthesis units have been traced to the addition products of dienes and nitrogen dioxide [Bretherick, 5th Ed., 1995]. | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [Health Hazard]
Vapors may cause dizziness or suffocation; contact may irritate skin and eyes. | [Chemical Properties]
colourless liquid | [Definition]
ChEBI: (E)-1,3-pentadiene is an alkadiene consisting of pentane with the two double bonds located at positions 1 and 3. |
