Description and Uses
2-Ethoxyethyl acetate is a colorless liquid witha mild, nonresidual odor. The odor threshold is 0.056 ppmin air. Molecular weight = 132.18; Specific gravity(H2O:1) = 0.98 at 20℃; Boiling point = 156℃; Freezing/Melting point = - 61.7℃; Vapor pressure = 2 mmHg at20℃; Flash point = 47℃; Autoignitiontemperature = 380℃. Explosive limits: LEL = 1.7%;UEL = 12.7%. The UEL is also reported as 14%. HazardIdentification (based on NFPA-704 M Rating System):Health 2, Flammability 2, Reactivity 0. Soluble in water;solubility = 23%
2-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.
