Chemische Eigenschaften
clear liquid
14% soluble in water, miscible with alcohol and oils. Poorly soluble in Propylene glycol.
Verwenden
Solvent for oils, cellulose esters, explosives, etc.
Verwenden
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).
Verwenden
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.
Vorbereitung Methode
Ethylene glycol diacetate is produced by direct esterification of Ethylene glycol with Acetic acid, using azeotropic conditions..
Allgemeine Beschreibung
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 Reaktionen
Water soluble.
Reaktivität anzeigen
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.
Brandgefahr
Ethylene glycol diacetate is combustible.
Flammability and Explosibility
Not classified
Sicherheitsprofil
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.
läuterung methode
Dry the di-ester with CaCl2, filter (excluding moisture) and fractionally distil it under reduced pressure. [Beilstein 2 IV 1541.]
