ETHYLENE Usage And Synthesis
Chemical Propertiescolourless gas
General DescriptionA colorless gas with a sweet odor and taste. ETHYLENE is lighter than air. ETHYLENE is easily ignited and a flame can easily flash back to the source of the leak. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Can cause explosion.
Air & Water ReactionsHighly flammable.
Reactivity ProfilePeroxidizable monomer may initiate exothermic polymerization of the bulk material [Bretherick 1979. p. 160]. ETHYLENE in the presence of aluminum chloride may undergo a violent reaction [J. Inst. Pet. 33:254. 1947]. Ozone and ETHYLENE react explosively [Berichte 38:3837]. ETHYLENE can polymerize at low pressure if catalyzed by titanium halides. (Sundaram, K. M, M. M. Shreehan, E. F. Olszewski. thylene. Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. 2001.)
Health HazardModerate concentration in air causes drowsiness, dizziness, and unconsciousness. Overexposure causes headache, drowsiness, muscular weakness.
