개요

Epoxy resins of the bisphenol A type are synthesized from epichlorhydrin and bisphenol A. This leads to bisphenol-A diglycidyl ether, which is the monomer of bisphenol-A-based epoxy resins. Sensitization to epichlorhydrin occurs mainly in workers in the epoxy-resin industry. Sensitization in individuals not working at epoxy resin plants is rare. It has however been described to occur after contact with a soil fumigant, due to solvent cement and in a worker in a pharmaceutical plant, in a division for drug synthesis. Epichlorhydrin was used for the production of both drugs propranolol and oxprenolol.

화학적 성질

Epichlorohydrin is a colorless liquid with a slightly irritating, chloroform-like odor.

물리적 성질

Clear, colorless, mobile liquid with a strong, irritating, chloroform-like odor. Odor threshold concentration is 0.93 ppm (quoted, Amoore and Hautala, 1983).

용도

Epichlorohydrin is used to make glycerol,epoxy resins, adhesive, and castings; asderivatives for producing dyes, pharmaceu-ticals, surfactants, and plasticizers; and asa solvent for resins, gums, paints, andvarnishes.

용도

Commercially the most important use is production of glycerine. Large volumes are consumed in nonglycerine areas, which largely consist of the various epoxy resins. It has use as a solvent and in the production of epichlorohydrin rubber.

용도

Solvent for natural and synthetic resins, gums, cellulose esters and ethers, paints, varnishes, nail enamels and lacquers, cement for Celluloid. As stabilizer.

정의

ChEBI: An epoxide that is 1,2-epoxypropene in which one of the methyl hydrogens is substituted by chlorine.

생산 방법

Epichlorohydrin can be prepared from 1,3-dichloropropanol-2, 2,3- dichloropropanol-1, or allyl chloride. Commercially it is prepared as an intermediate in glycerol synthesis via alkaline hydrolysis of glycerol dichlorohydrin. Both come from allyl chloride. Epichlorohydrin reacts with monohydric alcohols to give ethers by opening the oxide ring. It will react with ethers, aldehydes, ketones, organic acids and amines to give a wide variety of useful syntheses.

일반 설명

A clear colorless liquid with an irritating chloroform-like odor. Density 9.8 lb / gal. Flash point 87°F. Polymerizable. If polymerization takes place inside a closed container, the container is subject to violent rupture. Irritates the skin and respiratory system. Toxic by ingestion. A confirmed carcinogen. Vapors heavier than air. Used to make plastics and as a solvent.

공기와 물의 반응

Highly flammable. Water soluble.

반응 프로필

Epichlorohydrin may polymerize exothermically if heated or contaminated. Reacts explosively with aniline. Ignites on contact with potassium tert-butoxide. Reacts with trichloroethylene to give the explosive dichloroacetylene. Violent reaction with sulfuric acid or isopropylamine. Exothermic polymerization on contact with strong acids or bases, zinc, aluminum, aluminum chloride, iron, ferric chloride [Sax, 9th ed., 1996, p. 1469].

위험도

Toxic by inhalation, ingestion, and skin absorption; strong irritant, a carcinogen. Flammable, moderate fire risk. TLV: 0.5 ppm; animal carcinogen.

건강위험

Epichlorohydrin is toxic, carcinogenic, and astrong irritant. Its vapors can produce irrita-tion in the eyes, skin, and respiratory tract.Exposure to high concentration resulted indeath in animals, injuring the central nervoussystem. The liquid can absorb through humanskin, causing painful irritation of subcuta-neous tissues (ACGIH 1986). The symptomsof toxicity from high dosage in test animalswere paralysis of muscles and slow devel-opment of respiratory distress. Long expo-sures at 120 ppm for several hours resultedin lung, kidney, and liver injury in rats(Gage 1959). Ingestion by an oral routecaused tremor, somnolence, and ataxia inmice (NIOSH 1986). The toxic symptomsand lethal doses varied widely with animalspecies. The toxic metabolite of epichlorhy-drin could be ?- chlorohydrin ; thelatter was produced in vitro by rat livermicrosomes (Gingell et al. 1987).
A 25 ppm concentration may be detectableby odor. Exposure at this level may causeburning of the eyes and nose in humans.Above 100 ppm even a short exposure maybe hazardous to humans, causing nausea,dyspnea, lung edema, and kidney injury.
Epichlorohydrin is mutagenic and hasshown carcinogenicity in test animals. Itcaused tumors in the lungs and nose andat gastrointestinal and endocrine sites. Expo-sure to this compound caused harmful repro-ductive effects on fertility and birth defectsin mice.

건강위험

Epichlorohydrin is caustic as both a liquid and gas. Irritation of the eyes and skin, and skin sensitization has been observed. Exposure to epichlorohydrin has caused inflammation of the lungs, asthmatic bronchitis, and liver and kidney damage. In acute poisonings, death may be caused by respiratory paralysis.

화재위험

When heated to decomposition, Epichlorohydrin evolves highly toxic fumes of phosgene and carbon monoxide. Reactive and incompatible with strong oxidizers, strong acids, caustics, zinc, aluminum, chlorides of iron and aluminumand compounds with an active hydrogen atom, including water. Unstable, avoid heat, contaminants, strong acids and bases, certain curing agents such as ethylenediamine. Hazardous polymerization may occur.

화학 반응

Reactivity with Water Mild reaction; not likely to be hazardous; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Can polymerize in presence of strong acids and bases, particularly when hot; Inhibitor of Polymerization: None used.

잠재적 노출

Epichlorohydrin, an organochlorine, is used in the manufacture of many glycerol and glycidol derivatives and epoxy resins; as a stabilizer in chlorine-containing materials; as an intermediate in the preparation of cellulose esters and ethers, paints, varnishes, nail enamels, and lacquers; as a cement for celluloid. It is used as an intermediate in the manufacture of various drugs. Increased cancer risk.

Carcinogenicity

Epichlorohydrin is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.

환경귀착

Biological. Bridié et al. (1979) reported BOD and COD values of 0.03 and 1.16 g/g using filtered effluent from a biological sanitary waste treatment plant. These values were determined using a standard dilution method at 20 °C for a period of 5 d. When a sewage seed was used in a separate screening test, a BOD value of 0.16 g/g was obtained. The ThOD for epichlorohydrin is 1.21 g/g.
Chemical/Physical. Anticipated products from the reaction of epichlorohydrin with ozone or OH radicals in the atmosphere are formaldehyde, glyoxylic acid, and ClCH2O(O)OHCHO (Cupitt, 1980). Haag and Yao (1992) reported a calculated OH radical rate constant in water of 2.9 x 108/M?sec.

저장

Epichlorohydrin is stored in a well-ventilated,cool place isolated from combustible andoxidizable materials, all acids and bases,and anhydrous metal halides. Protect fromphysical damage. It is shipped in metaldrums.

운송 방법

UN2023 Epichlorhydrin, Hazard class: 6.1; Labels: 6.1-Poisonous materials, 3-Flammable liquid.

Purification Methods

Distil epichlorohydrin under atmospheric pressure, heat it on a steam bath with one-quarter its weight of CaO, then decant and fractionally distil it. [Beilstein 17 V 20.]

Toxicity evaluation

Epichlorohydrin is an alkylating agent that is mutagenic. It may induce DNA interstrand cross-links, chromosomal aberrations, and breaks. It is also an irritant, sensitizer, and corrosive.

비 호환성

May form explosive mixture with air. Slowly decomposes on contact with water. Heat or strong acids; alkalies, metallic halides, or contaminants can cause explosive polymerization. Violent reaction with strong oxidizers, aliphatic amines; alkanolamines, amines (especially aniline), alkaline earths; chemically active metals (chlorides of aluminum, iron zinc); powdered metals (aluminum, zinc); alcohols, phenols, organic acids; causing fire and explosion hazard. Will pit steel in the presence of water. Thermal decomposition forms highly toxic phosgene gas. May accumulate static electrical charges, and may cause ignition of its vapors.

폐기물 처리

Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≧100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal
