2-Methoxyethanol Chemical Properties,Uses,Production
Description
2-Methoxyethanol (2-ME), also known as ethylene glycol monomethyl ether, is a glycol ether that has been known since the 1920s, but its use significantly increased in the 1970s. Methoxyethanol is an E-series glycol ether derived from methanol and ethylene oxide. Other commonly used glycol ethers include ethoxyethanol, butoxyethanol, and methoxypropanol.
Chemical Properties
2-Methoxyethanol is a colorless liquid with a slight ethereal odor. The Odor Threshold is 0.9 2.3 ppm. It is miscible with water and with aliphatic and aromatic hydrocarbons. It is a solvent for essential oils, lignin, dammar, Elemi Essential Oil, ester gum, kauri, mastic, rosin, sandarac resin, shellac, Zanzibar, nitrocellulose, cellulose acetate, alcohol-soluble dyes, and many synthetic resins. Its solvency far cellulose esters are augmented when a ketone or halogenated hydrocarbon Is added.
Physical properties
Colorless liquid with a mild, ether-like odor. Experimentally determined detection and recognition odor threshold concentrations were <300 μg/m3 (<96 ppbv) and 700 μg/m3 (220 ppbv), respectively (Hellman and Small, 1974).
Uses
2-Methoxyethanol is considered a non-comedogenic raw material. It is used as a solvent in nail products and as a stabilizer in cosmetic emulsions. It is able to penetrate the skin and may cause skin irritation.
Uses
The primary use of 2-methoxyethanol is as a Solvent for low-viscosity cellulose acetate, natural resins, some synthetic resins and some alcohol-soluble dyes; in dyeing leather, sealing moistureproof cellophane; in nail polishes, quick-drying varnishes and enamels, wood stains. In modified Karl Fischer reagent: Peters, Jungnickel, Anal. Chem. 27, 450 (1955).
Preparation
From Methanol Plus Ethylene glycol, by heating under pressure.
Definition
ChEBI: 2-methoxyethanol is a hydroxyether that is ethanol substituted by a methoxy group at position 2. It has a role as a protic solvent and a solvent.
General Description
A clear colorless liquid. Flash point of 110°F. Less dense than water. Vapors are heavier than air.
Air & Water Reactions
Flammable. Water soluble.
Reactivity Profile
2-Methoxyethanol is incompatible with oxygen and strong oxidizing agents. Contact with bases may result in decomposition. Incompatible with acid chlorides and acid anhydrides. . 2-Methoxyethanol forms explosive peroxides.
Hazard
Toxic by ingestion and inhalation. Moderate fire risk. Toxic by skin absorption. Questionable carcinogen.
Health Hazard
2-Methoxyethanol is a teratogen and a chronic inhalation toxicant. The target organs are blood, kidney,and the central nervous system. In addi tion to inhalation, the other routes of expo sure are absorption through the skin, and ingestion. Animal studies indicated that over-exposure to this compound produced anemia, hematuria, and damage to the testes.In humans, inhalation of EGME vapors cancause headache, drowsiness, weakness, irrita tion of the eyes, ataxia, and tremor. The acuteinhalation toxicity, however, is low and anytoxic effect may be felt at a concentration ofabout 25–30 ppm in air
The oral and dermal toxicities of thiscompound in test animals were found to belower than the inhalation toxicity. Ingestioncan produce an anesthetic effect and in alarge dosage can be fatal. An oral intake ofabout 200 mL may cause death to humans.
LC50 value (mice): 1480 ppm/7 h,
LD50 value (rabbits): 890 mg/kg
EGME is a teratogen exhibiting fetotoxi city, affecting the fertility and the litter size,and causing developmental abnormalities inthe urogenital and musculoskeletal systemsin test animals.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Safety Profile
2-Methoxyethanol is moderately toxic to humans if ingested. Moderately toxic experimentally by ingestion, inhalation, shin contact, intraperitoneal, and intravenous routes. Human systemic effects by inhalation: change in motor activity, tremors, and convulsions. Experimental teratogenic and reproductive effects. A skin and eye irritant. Mutation data reported. When used under conditions that do not require the application of heat, thts material probably presents little hazard to health. However, in the manufacture of fused collars which require pressing with a hot iron, cases have been reported showing disturbance of the hemopoietic system with or without neurologcal signs and symptoms. The blood picture may resemble that produced by exposure to benzene. Two cases reported had severe aplastic anemia with tremors and marked mental dullness. The persons affected had been exposed to vapors of methyl "Cellosolve," ethanol, methanol, ethyl acetate, and petroleum naphtha. flame. A moderate explosion hazard. Can react with oxidizing materials to form explosive peroxides. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also GLYCOL ETHERS. Flammable liquid when exposed to heat or
Potential Exposure
2-Methoxyethanol is used as a jet fuel additive; solvent for protective coating; and in chemical synthesis. Ethylene glycol ethers are used as solvents for resins used in the electronics industry, lacquers, paints, varnishes, gum, perfume; dyes and inks; and as a constituent of painting pastes, cleaning compounds; liquid soaps; cosmetics, nitrocellulose, and hydraulic fluids.

Do not make an unconscious person vomit.Medical observation is recommended for 24- 48 h afterbreathing overexposure, as pulmonary edema may bedelayed. As first aid for pulmonary edema, a doctor orauthorized paramedic may consider administering a corticosteroid spray.
Carcinogenicity
There are no experimental carcinogenicity or cancer epidemiology data relating to this chemical , but some short-term test data are available and are summarized in the section on genetic and related cellular effects.
Environmental Fate
Photolytic. Grosjean (1997) reported an atmospheric rate constant of 1.25 x 10-11
cm3/molecule?sec at 298 K for the reaction of methyl cellosolve and OH radicals. Based on an
atmospheric OH concentration of 1.0 x 106 molecule/cm3, the reported half-life of methyl
cellosolve is 0.64 d (Grosjean, 1997).
Chemical/Physical. At an influent concentration of 1,000 mg/L, treatment with GAC resulted in
an effluent concentration of 342 mg/L. The adsorbability of the carbon used was 132 mg/g carbon
(Guisti et al., 1974).

Purification Methods
Peroxides can be removed by refluxing with stannous chloride or by filtration under slight pressure through a column of activated alumina. 2-Methoxyethanol can be dried with K2CO3, CaSO4, MgSO4 or silica gel, then distilled from sodium. Aliphatic ketones (and water) can be removed by making the solvent 0.1% in 2,4-dinitrophenylhydrazine and allowing to stand overnight with silica gel before fractionally distilling. [Beilstein 1 IV 2375.]
Incompatibilities
Vapors may form explosive mixture with air. Heat or oxidizers may cause the formation of unstable peroxides. Attacks many metals. Strong oxidizers may cause fire and explosions. Strong bases cause decomposition and the formation of toxic gas. Attacks some plastics, rubber and coatings. May accumulate static electrical charges, and may cause ignition of its vapors.
Waste Disposal
Concentrated waste containing no peroxides: discharge liquid at a controlled rate near a pilot flame. Concentrated waste containing peroxides: perforation of a container of the waste from a safe distance followed by open burning.
