ETHYLENE Usage And Synthesis
Chemical Propertiescolourless gas
Chemical PropertiesEthylene, an alkene is a colorless gas (at room temperature). Sweet odor. Minimum detectable odor 5 260 ppm.
UsesOxyethylene welding and cutting metals; manufacture of alcohol, mustard gas, and many other organics. manufacture of ethylene oxide (for plastics), "Polythene", polystyrene and other plastics. Plant growth regulator; used commercially to accelerate the ripening of various fruits.
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.)
HazardHighly flammable, dangerous fire and explosion risk; explosive limits in air 3–36% by volume. Simple asphyxiant; questionable carcinogen.
Health HazardModerate concentration in air causes drowsiness, dizziness, and unconsciousness. Overexposure causes headache, drowsiness, muscular weakness.
Safety ProfileSuspected carcinogen. A simple asphyxiant. High concentrations cause anesthesia. A common air contaminant. It is phytotoxic. A very dangerous fire hazard when exposed to heat or flame. Moderate explosion hazard when exposed to flame. A flammable gas. To figh fire, stop flow of gas, use Co2, dry chemical, or fine water spray. Mixtures with aluminum chloride explode in the presence of nickel catalysts, methyl chloride, or nitromethane. Explosive reaction with bromotrichloromethane (at 120℃/51 bar), carbon tetrachloride (25-100°C/30 bar). Explosive reaction with chlorine catalyzed by sunlight or UV light or in the presence of mercury(I) oxide, mercury(Ⅱ) oxide, or silver oxide. Mixtures with chlorotrifluoroethylene polymerize explosively when exposed to 50 kV gamma rays at 308 krad/hr. Has been involved in industrial accidents. Violent polymerization is catalyzed by copper above 4OO0C/54 bar. Incompatible with AlCl3, (CC4 + benzoyl peroxide), (bromotrichloromethane + NCh), 03, CCl4, Cl2, NOx, tetrafluoroethylene trifluorohypofluorite. When heated to decomposition it emits acrid smoke and irritating fumes
Potential ExposureEthylene is used in production of fabricated plastics, antifreeze; making fibers; to manufacture ethylene oxide, polyethylene for plastics, alcohol, mustard gas and other organics. It is used to accelerate ripening of fruit; as an anesthetic; and for oxyethylene welding and cutting of metals
First aidIf this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. If frostbite has occurred, seek medical attention immediately; do NOT rub the affected areas or flush them with water. In order to prevent further tissue damage, do NOT attempt to remove frozen clothing from frostbitten areas. If frostbite has NOT occurred, immediately and thoroughly wash contaminated skin with soap and water.
ShippingUN1962 Ethylene, Hazard Class: 2.1; Labels: 2.1-Flammable gas; UN1038 Ethylene, refrigerated liquid (cryogenic liquid), Hazard Class: 2.1; Labels: 2.1- Flammable gas. Cylinders must be transported in a secure upright position, in a well-ventilated truck. Protect cylinder and labels from physical damage. The owner of the compressed gas cylinder is the only entity allowed by federal law (49CFR) to transport and refill them. It is a violation of transportation regulations to refill compressed gas cylinders without the express written permission of the owner.
Purification MethodsPurify ethylene by passage through a series of towers containing molecular sieves or anhydrous CaSO4 or a cuprous ammonia solution, then conc H2SO4, followed by KOH pellets. Alternatively, it has been condensed in liquid nitrogen, with melting, freezing and pumping to remove air before passage through an activated charcoal trap, followed by a further condensation in liquid air. A sputtered sodium trap was used to remove oxygen. [Beilstein 1 IV 677.]
IncompatibilitiesA highly flammable gas at room temperature. Contact with oxidizers may cause explosive polymerization and fire. May be spontaneously explosive in sunlight or ultraviolet light when mixed with chlorine. Reacts violently with mixtures of carbon tetrachloride and benzoyl peroxide; bromotrichloromethane; aluminum chloride and ozone. Incompatible with acids, halogens, nitrogen oxides; hydrogen bromide; aluminum chloride; chlorine dioxide; nitrogen dioxide. May accumulate static electrical charges, and may cause ignition of its vapors.
Waste DisposalReturn refillable compressed gas cylinders to supplier
