clear liquid14% soluble in water, miscible with alcohol and oils. Poorly soluble in Propylene glycol.
??
Ethylene glycol diacetate may be used as an acyl donor for the in situ generation of peracetic acid, during the chemoenzymatic synthesis of caprolactone. It may be employed as a precursor for the enzymatic synthesis of poly (ethylene glutarate).?? ??
Colorless liquid with a mild pleasant odor. Density 9.2 lb /gal. Flash point 191°F. Boiling point 369°F. Combustible but requires some effort to ignite. Used in the manufacture of perfumes, printing ink, lacquers and resins.??? ?? ??
Water soluble.?? ???
Ethylene glycol diacetate reacts with aqueous acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction with caustic solutions. Flammable hydrogen is generated with alkali metals and hydrides.????
Inhalation is not hazardous. Liquid causes mild irritation of eyes. Ingestion causes stupor or coma.????
Ethylene glycol diacetate is combustible.Safety Profile
Moderately toxic by intraperitoneal route. Mildly toxic by ingestion and skin contact. An eye irritant. Combustible when exposed to heat or flame; can react with oxidzing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.Purification Methods
Dry the di-ester with CaCl2, filter (excluding moisture) and fractionally distil it under reduced pressure. [Beilstein 2 IV 1541.]????????? ?? ?? ? ???
