개요

2-Butoxyethanol is a clear, colourless liquid with ether-like smell.2-Butoxyethanol is usually produced by a reaction of ethylene oxide with butyl alcohol, but it may also be made by the reaction of ethylene glycol with dibutyl sulphate. 2-Butoxyethanol is widely used as a solvent in protective surface coatings such as spray lacquers, quick-dry lacquers, enamels, varnishes, and latex paints. It is also used as an ingredient in paint thinners and strippers, varnish removers, agricultural chemicals, herbicides, silicon caulks, cutting oils, and hydraulic fluids and as metal cleaners, fabric dyes and inks, industrial and household cleaners (as a degreaser), and dry-cleaning compounds. It is also used in liquid soaps and in cosmetics. 2-Butoxyethanol acetate has been reported to be present in air, water, and soil as a contaminant and exposure to it occurs during its manufacture and use as an intermediate in the chemical industry, and during the formulation and use of its products in multiple industrial activities. The acetate form of 2-butoxyethanol is 2-butoxyethanol acetate and also known as ethylene glycol monobutyl ether acetate.

화학적 성질

Ethylene glycol monobutyl ether is colorless liquid, miscible in alI proportions with many ketones, ethers, alcohols, aromatic paraffin and halogenated hydrocarbons. More specifically, it mixes in all proportions with acetone, benzene, carbon tetrachloride, ethyl ether, n-heptane and water. Because of its excellent solvency, low evaporation rate and high dilution ratios, it is used as a solvent in the manufacture and formulation of lacquers, enamels, inks and varnishes, employing such resins as alkyd, phenolic, nitrocellulose, maleic modified, styrene and epoxy. In lacquers butyl "Cellosolve" imparts a slow evaporation rate, strengthens blush resistance, heightens gloss, improves flow-out and helps prevent orange peel. Hot spray lacquers usually contain about 10% of "Dowanol" EB based on the solvent-diluent weight.

화학적 성질

2-Butoxyethanol is a clear colorless liquid with an ether-like smell and belongs to the fam ily of glycol ether/alkoxy alcohol. 2-Butoxyethanol is miscible in water and soluble in most organic solvents. 2-Butoxyethanol does not occur naturally. It is usually produced by reacting ethylene oxide with butyl alcohol. It is used as a solvent for nitrocellulose, natural and synthetic resins, soluble oils, in surface coatings, spray lacquers, enamels, varnishes, and latex paints, as an ingredient in paint thinners, quick-dry lacquers, latex paint, and strippers, varnish removers, and herbicides. 2-Butoxyethanol is also used in textile dyeing and printing, in the treatment of leather, in the production of plasticizers, as a stabilizer in metal cleaners and household cleaners, and in hydraulic fl uids, insecticides, herbicides, and rust removers. It is also used as an ingredient in liquid soaps, cosmetics, industrial and household cleaners, dry-cleaning compounds, and as an ingredient in silicon caulks, cutting oils, and hydraulic fl uids. 2-Butoxyethanol is a fi re hazard when exposed to heat, sparks, or open flames

위험도

A toxic material. Eye and upper respiratory tract irritant. Questionable carcinogen.

건강위험

Vapors irritate eyes and nose. Ingestion or skin contact causes headache, nausea, vomiting, dizziness.

건강위험

2-Butoxyethanol is present in a variety of consumer products, including cleaning agents and surface coatings, such as paints, lacquers, and varnishes. 2-Butoxyethanol is readily absorbed following inhalation, oral, and dermal exposure. 2-Butoxyethanol is released into air or water by different industrial activities and facilities that manu facture, process, or use the chemical. Exposure to 2-butoxyethanol causes irritating effects to the eyes and skin, but it has not induced skin sensitization in guinea pigs. Information on the human health effects associated with exposure to 2-butoxyethanol is limited. However, case studies of individuals who had attempted suicide by ingest ing 2-butoxyethanol-containing cleaning solutions suffered poisoning with symp toms such as hemoglobinuria, erythropenia, and hypotension, metabolic acidosis, shock, non-cardiogenic pulmonary edema, and albuminuria, hepatic disorders and hematuria.

건강위험

EGBE exhibited mild to moderate toxicity in test animals. The toxic symptoms are similar to those of EGME. It is an irritant to the eyes and skin. The toxic routes of exposure are inhalation, ingestion, and absorption through the skin. In animals, prolonged exposure to high concentrations or high oral intake caused hematuria, kidney damage, and increased osmotic fragility of the blood cells. Such effects, however, were noted only at a high level of exposures (i.e., 700 ppm for 7 hours in mice, the minimal lethal concentration) (Werner et al. 1943). The other toxic effects noted were respiratory distress, change in motor activity, and lung, kidney, and liver changes. EGBE is absorbed rapidly through the skin. A 3-minute contact with 0.56 mL/kg over a 4.5% skin area produced the increased red blood cell fragility within an hour in rabbits (Carpenter et al. 1956; ACGIH 1986). Rabbits treated percutaneously with 0.08 to 0.25 mL/kg EGBE developed prostration, hypothermia, hemoglobinuria, spleen congestion, and kidney enlargement (Duprat and Gradiski 1979). Some rabbits survived and did not show the foregoing histopathological signs. The percutaneous toxicity of EGBE was found to be greater than that of the industrial solvents carbon tetrachloride and dimethyl formamide but lower than that of 2-chloroethanol and 1,1,2-trichloroethane (Wahlberg and Boman 1979). Chronic exposures at lower concentrations produced mild hemolytic anemia and thymic atrophy in rats (Grant et al. 1985). Subchronic oral doses of undiluted EGBE produced a significant dosedependent decrease in the blood hemoglobin concentration (Krasavage 1986). Such an effect was manifested at the moderately high dose of 222–885 mg/kg/day for 5 days/week over a 6-week period. No adverse effects on the testes, bone marrow, thymus, or white blood cells were observed
LC50 value, (rats): 450 ppm/4 h
LD50 value, oral (rats): 530 mg/kg
In humans the toxic effects of EGBE are generally low. Exposure to 200 ppm for 8 hours may produce nausea, vomiting, and headache. In a study on male volunteers exposed to 20 ppm of EGBE for 2 hours during light physical exercise, Johansson and coworkers (1986) determined that the respiratory uptake of EGBE was about 57% of the inspired amount; its concentration in the blood reached a plateau level of 0.87 mg/L; the elimination half-time and the mean residence time were 40 and 42 minutes, respectively. The amount excreted in the urine was <0.03% of the total intake, whereas that of butoxyacetic acid ranged from 17 to 55%.
Noreproductivetoxicity hasbeenreported in male animals. No teratogenic effects have been reported in females. However, when pregnant animals received high oral or inhalation doses of this material, signs of embryo–fetal toxicity were reported but only at doses that were maternally toxic. Unlike EGME, EGBE caused no testicular atrophy (Doe 1984; Nagano et al. 1984).
