Information on basic physicochemical properties
- Physical state
1,3-pentadiene is 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.

Possibility of hazardous reactions
HIGHLY FLAMMABLE, DANGEROUS FIRE RISK.The vapour is heavier than air and may travel along the ground; distant ignition possible.1,3-PENTADIENE 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].

Persistence and degradability
No biodegradation data regarding 1,3-pentadiene were located(SRC), however data on a similar compound, 1,3-butadiene are available(1-4). Laboratory studies employing pure bacterial cultures isolated from lake and soil samples were shown to degrade 1,3-butadiene to 1,2-epoxybutene, however it is not clear what the rate of degradation will be under environmental conditions(1-3). The biodegradation half-life of 1,3-butadiene in aerobic waters has been reported as 7 days and the half-life in anaerobic waters was reported as 28 days(4). These data suggest that 1,3-pentadiene will also undergo biodegradation under similar conditions(SRC).
Bioaccumulative potential
An estimated BCF of 15 was calculated for 1,3-pentadiene(SRC), using a log Kow of 2.44(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
The Koc of 1,3-pentadiene is estimated as 500(SRC), using a log Kow of 2.44(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1,3-pentadiene is expected to have low mobility in soil(SRC).
Other adverse effects
no data available
Disposal methods
ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
