Ethylene glycol diacetate Usage And Synthesis

Chemical Properties

clear liquid

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).

Uses

Solvent for oils, cellulose esters, explosives, etc.

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.]
