Details

chemical properties colourless liquid with a petrol-like odour
definition chebi: a cycloalkene that is cyclopentane having one endocyclic double bond.
general description a colorless liquid. less dense than water and insoluble in water. flash point below 0°f. vapors heavier than air. inhalation of high concentrations may be narcotic. used to make rubber and plastics.
air & water reactions highly flammable. insoluble in water.
reactivity profile cyclopentene 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.
health hazard may be harmful by inhalation, ingestion, or skin absorption. may cause eye and skin irritation.
fire hazard special hazards of combustion products: vapor may travel considerable distance to a source of ignition and flashback. explosion may occur under fire condition.
