1,3,5,7-CYCLOOCTATETRAENE Usage And Synthesis
Chemical Propertiescolourless to light yellow liquid
UsesUsed in the synthesis of highly organic film for silicon surfaces to improve its chemical and physical properties. 1 Used in liquid state organic dye lasers. 2 Used as triplet state quencher to reduce dye blinking. 3
DefinitionChEBI: An antiaromatic annulene that is cyclooctane having four double bonds at positions 1, 3, 5 and 7.
General DescriptionA colorless liquid. May irritate skin and eyes. Less dense than water and insoluble in water. Flash point 70°F. Vapors heavier than air. Used to make rubber.
Air & Water ReactionsHighly flammable. Insoluble in water.
Reactivity Profile1,3,5,7-CYCLOOCTATETRAENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas.
Health HazardInhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Purification MethodsPurify the triene by shaking 3mL with 20mL of 10% aqueous AgNO3 for 15minutes, then filtering off the AgNO3 complex which precipitates. The precipitate is dissolved in water and added to cold concentrated ammonia to regenerate the cyclooctatetraene which is fractionally distilled under vacuum onto molecular sieves and stored at 0o. It is passed through a dry alumina column before use [Broadley et al. J Chem Soc, Dalton Trans 373 1986]. [Beilstein 5 I 228, 5 IV 1331.]
