2-(2-Methoxyethoxy)ethanol Usage And Synthesis
  • Chemical PropertiesDiethylene glycol monomethyl ether is a colorless, stable hygroscopic liquid with an agreeable odor. It is completely miscible with water, ketones, alcohol, ethers, aromatic hydrocarbons and halogenated hydrocarbons. More specifically, it is miscible with acetone, benzene, carbon tetrachloride, ethyl ether, methanol and water. It is a solvent for dyes, oils, fats, waxes, many natural and synthetic resins, nitrocellulose and cellulose acetate. It is used as a high-boiling solvent in such formulations as printing inks ond pastes, stamp pad inks, textile dye pastes, lacquers, and synthetic resin coatings. Its presence in lacquers eases brushability and flow-out, and minimizes lifting of undercoats.
  • UsesUsed in the same way as 2-ethoxyethanol where a solvent with a higher boiling point is required.
  • UsesDiethyleneglycolmonomethylether(DGME) is used as a thermally stable solvent for many substances, such as nitrocellulose, lacquers, varnishes, and dyes.
  • DefinitionChEBI: A hydroxypolyether that is the monomethyl ether derivative of diethylene glycol.
  • General DescriptionColorless liquid with a sweet odor. Floats and mixes with water.
  • Air & Water ReactionsOxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick 1979 p.151-154, 164]. Water soluble.
  • Reactivity Profile2-(2-Methoxyethoxy)ethanol is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
  • Health HazardLiquid may irritate eyes.
  • Health HazardDGME is a mild to moderate toxicant via ingestion or absorption through the skin. High doses produced lowering of hemoglobin levels and increased relative kidney weight. Renaldamagemay occurnear the lethal dose. Eye contact of the liquid can result in mild to moderate irritation
    LD50 value, oral (guinea pigs): 4160 mg/kg
    Preliminary developmental toxicity test in pregnant mice dosed with DGME indicated teratogenicity of this compound (Hardin et al. 1987; Cheever et al. 1988). Earlier, Doe (1984) reported no teratogenic property of DGME when administered subcutaneously in rats up to 100 mL/kg. In comparison, EGME produced effects at 40 mL/kg..
  • Fire Hazard2-(2-Methoxyethoxy)ethanol is combustible.
  • Safety ProfileModerately toxic by skin contact and intraperitoneal routes. Mildly toxic by ingestion. An experimental teratogen. Other experimental reproductive effects. An eye irritant. Combustible when exposed to heat or flame; can react with oxidzing materials. Reacts violently with Ca(OCl)2, chlorosulfonic acid, and oleum. To fight fire, use dry chemical, alcohol foam, water spray or mist, CO2. When heated to decomposition it emits acrid smoke and irritating fumes. See also GLYCOL ETHERS.
  • Purification MethodsPurify as for diethylene glycol mono-n-butyl ether. [Beilstein 1 IV 2392.]
  • Waste DisposalDGME is mixed with a combustible solvent and burned in a chemical incinerator.
