Hazards summaryEpichlorohydrin is mainly used in the production of epoxy resins. Acute (short-term) inhalation exposure to epichlorohydrin in the workplace has caused irritation to the eyes, respiratory tract, and skin of workers. At high levels of exposure, nausea, vomiting, cough, labored breathing, inflammation of the lung, pulmonary edema, and renal lesions may be observed in humans. Chronic (long-term) occupational exposure of humans to epichlorohydrin in air is associated with high levels of respiratory tract illness and hematological effects. Damage to the nasal passages, respiratory tract and kidneys have been observed in rodents exposed to epichlorohydrin by inhalation for acute or chronic duration. An increased incidence of tumors of the nasal cavity has been observed in rats exposed by inhalation. EPA has classified epichlorohydrin as a Group B2, probable human carcinogen.Can cause severe skin burns and a skin sensitizerInhalation of vapor can cause lung edema and asthma-like reactions[ICSC] In high-dose animal studies, epichlorohydrin causes testicular damage and sterility.

Environmental fateTERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 40(SRC), determined from a log Kow of 0.45(2) and a regression-derived equation(3), indicates that epichlorohydrin is expected to have very high mobility in soil(SRC). Volatilization of epichlorohydrin from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 3.0X10-5 atm-cu m/mole(SRC), calculated from a vapor pressure of 16.4 mm Hg(4) and water solubility of 65,900 mg/L(5). The potential for volatilization of epichlorohydrin from dry soil surfaces may exist based upon the vapor pressure(4). Epichlorohydrin may undergo hydrolysis in moist soil surfaces based on a hydrolysis half-life of 8.2 days in distilled water(6). Epichlorohydrin achieved 3% of the theoretical BOD in a sewage sludge over a 5 day incubation period, but achieved 14% of the theoretical BOD following acclimation(7), suggesting that biodegradation in acclimated soils may be important(SRC).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 40(SRC), determined from a log Kow of 0.45(2) and a regression-derived equation(3), indicates that epichlorohydrin is not expected to adsorb to suspended solids and sediment in water(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 3.0X10-5 atm-cu m/mole(SRC), calculated from its vapor pressure of 16.4 mm Hg(4) and water solubility of 65,900 mg/L(5). Using this estimated Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 19 hours and 12 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low. The hydrolysis half-life of epichlorohydrin is 8.2 days in distilled water and 5.3 days in simulated seawater(8). Epichlorohydrin achieved 3% of the theoretical BOD in a sewage sludge over a 5 day incubation period, but achieved 14% of the theoretical BOD following acclimation(9)thus biodegradation in acclimated water may be important(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), epichlorohydrin, which has a vapor pressure of 16.4 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere.

Toxicity summaryIDENTIFICATION: Epichlorohydrin is a colorless liquid in which the vapor forms explosive mixtures in air. Phosgene, hydrogen chloride and carbon monoxide are liberated while burning. Acids, caustic solutions and halide salts initiate polymerization reactions. The compound is very reactive with metals such as zinc, aluminum, anhydrous metal halides, strong acids and bases along with alcohol containing materials. In the presence of moisture epichlorohydrin is corrosive to steel. Epichlorohydrin has a chloroform like odor. It is soluble in water. Epichlorohydrin is used for the manufacture of glycerine and unmodified epoxyresins. It is also used in the production of elastomers, glycidil ether, cross linked food starch, wet strength resins for the paper industry, water treatment resins, surfactants, ion exchange resins, plasticizers, dyestuffs, pharmaceutical products, emulsifiers, lubricants and adhesives. HUMAN EXPOSURE: On the basis of use patterns and the chemical and physical properties of epichlorohydrin, human exposure is mainly occupational, through vapor inhalation, direct skin contact and a slight exposure resulting from food consumption. Five human volunteers showed significant electroencephalogram changes in the voltage spikes of the alpha rhythm when they were exposed to a vapor of epichlorohydrin. Burning of the eyes and nasal mucosa was reported along with throat irritation. Seven cases of epichlorohydrin spills on the hands, thighs or feet have been described. In two cases epichlorohydrin was mixed with methanol. All spills resulted in protracted chemical burns with a latent period of between 10 minutes and several hours before the first symptoms appeared. Redness, swelling, edema, erosion and ulceration. One case was reported of a 39 year old man who inhaled a few deep breaths of epichlorohydrin vapor occured. Initially only a slight irritation of the eyes and throat was experienced with headache, nausea and vomitinglater chronic asthmatic bronchit
Ecotoxicity excerpts/AQUATIC SPECIES/ The 14 day LC50 value of epichlorohydrin to the guppy (Poecilia reticulata) was determined. These data were investigated through the construction of a quantitative structure-activity relationship (QSAR). Both hydrophobicity and alkylating potency of the compound were found to be necessary parameters for the satisfactory description of the LC50 data. The log LC50 experimental data for epichlorohydrin was 0.85 umol/L as compared to the calculated QSAR value of 1.08 umol/L.

Applications & Uses

Description

Epichlorohydrin is a kind of organochlorine compound as well as epoxide. It can be used as an industrial solvent. It is a highly reactive compound, and can be used for the production of glycerol, plastics, epoxy glues and resins, and elastomers. It can also be used for the production of glycidyl nitrate and alkali chloride, used as the solvent of cellulose, resins, and paint as well as being used as an insect fumigant. In biochemistry, it can be used as a crosslinking agent for the production of Sephdex size-exclusion chromatography resins. However, it is a potential carcinogen, and can cause various kinds of side effects on respiratory tract and kidneys. It can be manufactured through the reaction between allyl chloride with hypochlorous acid as well as alcohols.

Uses

Epichlorohydrin is mainly used in the production of epoxy resins. It was also used as a solvent for paints, varnishes, lacquers, cellulose esters and ethers, and gums. Epichlorohydrin was historically used as an insecticide fumigant.

Description

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.

Uses

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.

Uses

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

Uses

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.
