Ethylene Glycol Diacetate CAS#111-55-7
Ethylene Glycol Diacetate, also known as ethylene glycol diacetate, is a compound with an ethylene glycol (1,2-ethanol) backbone, in which each hydroxyl group is esterified with an acetate group (-O-C(=O)-CH₃). It is typically a clear, colorless liquid, occasionally slightly yellow, with an acetate-like odor. Its physical properties include a density of approximately 1.1043 g/mL (20°C), a melting point of -41°C, a boiling range of 185–190°C, a refractive index of 1.4162 (20°C), and an open-cup flash point of 96°C.
The compound exhibits typical ester characteristics and is readily hydrolyzed by strong alkalis or inorganic acids to yield ethylene glycol and acetic acid. For instance, reaction with sodium hydroxide breaks its ester bonds, producing the corresponding alcohol and carboxylate. Additionally, it is reactive in alcoholysis reactions and can serve as an acetate donor in organic synthesis processes.

Product Usage
Ethylene Glycol Diacetate (EGDA) can serve as a solvent for oils, cellulose esters, explosives, and similar materials. It provides excellent flow properties in baking varnishes and enamels, particularly where thermoplastic acrylic resins are applied. EGDA is also an effective solvent for cellulosic coatings and can be used in certain ink systems, including screen printing inks. Additionally, it has applications as a fragrance fixative and finds use in waterborne adhesives.
EGDA can act as an acyl donor for in situ generation of peracetic acid in the chemoenzymatic synthesis of caprolactone. It also serves as a precursor in the enzymatic production of poly(ethylene glutarate).
