Ethylene glycol monoethyl ether acetate Usage And Synthesis
  • DescriptionEthylene glycol monoethyl ether acetate (also known as 2-Ethoxyethyl Acetate) belongs to the family of glycol ethers that are commonly used in paints and cleaners, e. g. for cellulose nitrate paints. Its properties can also be exploited in coatings for brushing on, dip coating and spraying, and for stove enamels. 2-Ethoxyethyl acetate is also used as a liquid pesticide product1. It is used as a solvent dissolve resin, leather, ink, for the formulation of paints, lacquers and varnishes for industrial use. It is also used to study the field evaluation of a passive badge for measuring the level of 2-ethoxyethyl acetate. It is also used to study the field evaluation of a passive badge. Another application for 2-Ethylhexyl Acetate is as an additive in cleaners and paint removers.
  • Chemical Propertiescolourless liquid
  • Chemical Properties2-Ethoxyethyl acetate is a colorless liquid with a mild, nonresidual odor. The Odor Threshold is 0.056 ppm in air
  • Physical propertiesColorless liquid with a faint, pleasant odor. Experimentally determined detection and recognition odor threshold concentrations were 300 μg/m3 (60 ppbv) and 700 μg/m3 (130 ppbv), respectively (Hellman and Small, 1974). Nagata and Takeuchi (1990) reported an odor threshold concentration of 49 ppbv.
  • UsesIn the coatings industry, especially in the semiconductor industry; solvent for nitrocellulose and some resins
  • Uses2-Ethoxyethyl acetate is used as a solvent dissolve resin, leather, ink, for the formulation of paints, lacquers and varnishes for industrial use. It is also used to study the field evaluation of a passive badge for measuring 2-ethoxyethyl acetate.
  • UsesSolvent for nitrocellulose, oils, and resins; retards “blushing” in lacquers, varnish removers, wood stains, textiles, and leather.
  • General DescriptionA clear colorless liquid with a pleasant odor. Flash point of 120°F. Less dense than water. Vapors are heavier than air.
  • Air & Water ReactionsFlammable. Slightly soluble in water.
  • Reactivity ProfileMixing Ethylene glycol monoethyl ether acetate in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, oleum, and vinyl acetate, NFPA 1991.
  • HazardToxic by ingestion and skin absorption. Toxic by skin absorption.
  • Health HazardVapors irritate nose and eyes in high concentrations. Liquid irritates skin in prolonged or repeated contact.
  • Fire HazardHIGHLY 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 ProfileModerately toxic by ingestion and intraperitoneal routes. A skin and eye irritant. An experimental teratogen. Other experimental reproductive effects. Flammable liquid when exposed to heat or flame; can react with oxidizing materials. Moderate explosion hazard in the form of vapor when heated. Mild explosions have occurred at the end of disullations. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also GLYCOL ETHERS.
  • Potential ExposureThis material is used as a solvent for many different purposes; including for nitrocellulose and other resins. Used in automobile lacquers to retard evaporation and impart a high gloss.
  • Environmental FateBiological. Bridié et al. (1979) reported BOD and COD values of 0.74 and 1.76 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. The ThOD for 2-ethoxyethyl acetate is 1.82 g/g.
    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).
  • ShippingUN1172 Ethylene glycol monoethyl ether acetate, Hazard Class: 3; Labels: 3-Flammable liquid
  • Purification MethodsShake the ethoxy-ethane with anhydrous Na2CO3, filter and distil it in a vacuum. Redistillation can then be carried out at atmospheric pressure. [Dunbar & Bolstad J Org Chem 21 1041 1956, Beilstein 2 IV 214.]
  • IncompatibilitiesMay form explosive mixture with air. Incompatible with strong acids; strong alkalies; nitrates. Violent reaction with oxidizers. May form unstable peroxides. Softens many plastics. Attacks some plastics, rubber, and coatings
  • Waste DisposalDissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
