colourless liquid??? ??
Colorless 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.??
Solvent for nitrocellulose, oils, and resins; retards “blushing” in lacquers, varnish removers, wood stains, textiles, and leather.?? ??
A clear colorless liquid with a pleasant odor. Flash point of 120°F. Less dense than water. Vapors are heavier than air.??? ?? ??
Flammable. Slightly soluble in water.?? ???
Mixing 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.???
Toxic by ingestion and skin absorption. Toxic by skin absorption.????
Vapors irritate nose and eyes in high concentrations. Liquid irritates skin in prolonged or repeated contact.????
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
Moderately 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.??? ??
This 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.????
Biological. 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).

UN1172 Ethylene glycol monoethyl ether acetate, Hazard Class: 3; Labels: 3-Flammable liquidPurification Methods
Shake 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.]? ???
May 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??? ??
Dissolve 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.??????????? ?? ?? ? ???
