Chemical Properties
clear liquid
14% soluble in water, miscible with alcohol and oils. Poorly soluble in Propylene glycol.
Uses
Solvent for oils, cellulose esters, explosives, etc.
Uses
EGDA imparts excellent flow properties in baking lacquers and enamels and where thermoplastic acrylic resins are used. It is also a good solvent for cellulosic coatings and can be used in some ink systems such as screen inks. It has found use as a perfume fixative, and has reported applications in waterborne adhesives.
Uses
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).
Production Methods
Ethylene glycol diacetate is produced by direct esterification of Ethylene glycol with Acetic acid, using azeotropic conditions..
General Description
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.
Air & Water Reactions
Water soluble.
Reactivity Profile
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.
Health Hazard
Inhalation is not hazardous. Liquid causes mild irritation of eyes. Ingestion causes stupor or coma.
Fire Hazard
Ethylene glycol diacetate is combustible.
Flammability and Explosibility
Not classified
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.]
