75-21-8 Usage

Description

Ethylene oxide (C2H4O) is a kind of cyclic ether with important industrial applications. Although it is highly toxic and dangerous for household application and consumers to use, it can be used for the manufacture of many important industrial and commercialized products as well as some chemicals and intermediates. For example, it is very useful in the production of detergents, thickeners, solvents, plastics, and many kinds of organic chemicals such as ethylene glycol, ethanolamines, simple and complex glycols, polyglycol ethers, and other compounds. It is also a commonly sterilization methods used in the healthcare industry. In addition, it can be used as an accelerator of maturation of tobacco leaves and fungicide, as well as the main component of thermobaric weapons (fuel-air explosives). In industry, it is generally manufactured through direct oxidation of ethylene. In low doses, it can be used as a pesticide and a sterilizing agent owing to its effect of causing DNA damage. However, this property also make it a potential carcinogen.

General Description

A clear colorless gas with an ethereal odor. Flash point below 0°F. May polymerize exothermically if heated or contaminated. If the polymerization takes place inside a container, the container may rupture violently. Vapors may burn inside a container. Vapors irritate the eyes, skin, and respiratory system. Prolonged skin contact may result in delayed burns. Less dense than water. Vapors heavier than air. Vapors very toxic. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Used to make other chemicals, as a fumigant and industrial sterilant (AAR, 1999).

Uses

Fumigant for foodstuffs and textiles; to sterilize surgical instruments; agricultural fungicide. In organic syntheses, especially in the production of ethylene glycol. Starting material for the manufacture of acrylonitrile and nonionic surfactants.

Fire Hazard

Severe explosion hazard when exposed to heat or flame. Irritating vapors are generated when heated. Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. Vapor forms explosive mixtures with air over a wide range. Liquid is not detonable but the vapor may be readily initiated into explosive decomposition. Avoid metal fittings containing copper, silver, mercury or magnesium; ammonia, oxidizing agents; acids, organic bases; amines; certain salts; alcohols; mercaptans, ferric chloride; magnesium perchlorate; m-nitroaniline; trimethylamine, potassium, tin chlorides; alkanethiols; bromoethane; aluminum chloride; aluminum oxide; iron chlorides; and iron oxides. Avoid air, heat, acids and bases, metal or metal chloride catalysts. Hazardous polymerization may occur. Avoid acids; covalent halides such as chlorides of aluminum, iron (III), tin (IV); basic materials like alkali hydrides, ammonia, amines, and potassium; catalytically active solids such as aluminum or iron oxides or rust, chlorides of boron, aluminum, tin, and iron; some carbonates; and metals such as copper and copper alloys

Contact allergens

Ethylene oxide is a very strong irritant widely used in the chemical industry, and as a sterilizer of medical supplies, pharmaceutical products, and food. It can produce immediate (urticaria, asthma, anaphylaxis) or delayed reactions (irritant rather than allergic contact dermatitis). For example, residues in masks or dressings can produce irritant contact dermatitis.In delayed contact allergy, it seems that cross-reaction can be observed to epichlorhydrin or epoxypropane

Agricultural Uses

Fungicide and fumigant: Ethylene oxide is used as a fumigant for spices, seasonings, and foodstuffs and as an agricultural fungicide. When used directly in the gaseous form or in nonexplosive gaseous mixtures with nitrogen or carbon dioxide, ethylene oxide can act as a disinfectant, fumigant, sterilizing agent, and insecticide. It is a man-made chemical used as an intermediate in organic synthesis for ethylene glycol, polyglycols, glycol ethers, esters, ethanolamines, acrylonitrile, plastics, and surface-active agents. It is also used as a fumigant for textiles and for sterilization, especially for surgical instruments. It is used in drug synthesis and as a pesticide intermediate. Not approved for use in EU countries. Actively registered in the U.S.

Purification Methods

Dry oxirane with CaSO4, then distil it from crushed NaOH. It has also been purified by passage, as a gas, through towers containing solid NaOH. [Beilstein 17/1 V 3.]

Definition

ChEBI: A saturated organic heteromonocyclic parent that is a three-membered heterocycle of two carbon atoms and one oxygen atom.

Reactivity Profile

Colorless gas at room temperature (b.p. 11°C), confirmed carcinogen. Highly flammable, severe explosion hazard when exposed to flame. The autoignition temperature may be as low as 140° C in presence of rust. Rapid compression of the vapor with air causes explosion. ETHYLENE OXIDE vapor may be initiated into explosive decomposition in absence of air [Hess, L. G., et al., Ind. Eng. Chem., 1950, 42, p. 1251]. Metal fittings containing magnesium, copper or silver should be avoided, since traces of acetylene in ETHYLENE OXIDE may produce metal acetylides capable of detonating the vapor [MCA SD-38, 1971]. Violent polymerization occurs on contact with strong bases (alkali hydroxides, ammonia) or acids, amines, metallic potassium, oxides (aluminum oxide, iron oxide, rust), covalent halides (aluminum chloride, ferric chloride, tin(IV) chloride) [Gupta, A. K., J. Soc. Chem. Ind., 1949, 68, p. 179]. Violent reaction with m-nitroaniline, magnesium perchlorate, mercaptans, thiols, triethylamine [Bretherick, 5th ed., 1995, p. 316]. ETHYLENE OXIDE and SO2 can react violently in pyridine solution with pressurization if ETHYLENE OXIDE is in excess (Nolan, 1983, Case History 51).

Chemical Properties

Ethylene oxide is the simplest cyclic ether. It is a colourless gas or liquid and has a sweet, etheric odour. Etylene oxide is a flammable and very reactive and explosive chemical substance. On decomposition, vapours of pure ethylene oxide mix with air or inert gases and become highly explosive. Industrial use of ethylene oxide is extensive, as an intermediate in the production of monoethylene glycol, diethylene glycol, triethylene glycol, poly(ethylene) glycols, ethylene glycol ethers, ethanolamine, ethoxylation products of fatty alcohols, fatty amines, alkyl phenols, cellulose, and poly(propylene glycol). It is also used as a fumigant fungicide and insecticide, in the sterilisation of surgical instruments/ equipments and heat-sensitive materials in the hospital, in the sterilisation/fumigation of some imported foods, in the fumigation of books and archival materials in museums, and in the fumigation of furs, textiles, and furniture.

Air & Water Reactions

Highly flammable. Flammable over a wide vapor-air concentration range. Must be diluted on the order of 24 to 1 with water to lose flammability. Soluble in water.

Health Hazard

ETHYLENE OXIDE can cause death. Lowest inhalation concentration causing toxic effects is 12500 ppm/10 seconds. It is a strong skin irritant. Neurological disorders and even death have been reported.
