This FAQ answers three buyer questions about ethylene glycol diacetate: how to identify it and review its key specifications, where it is used, and how to store it during transport and storage.
What is ethylene glycol diacetate?
Ethylene glycol diacetate, also called glycol diacetate or EGDA, is a colorless, transparent, low-odor liquid with a very slow evaporation profile. Its CAS number is 111-55-7, and its molecular formula is C6H10O4. It dissolves in water at 21.3% at 20 °C and is easily soluble in alcohol, ether, and other organic solvents.
Buyers can review these technical values when matching EGDA with a formulation or internal specification:
| Property | Value |
|---|---|
| EGDA content | ≥98.0% |
| Acidity, as HAC | ≤0.10% |
| Moisture | ≤0.10% |
| Color, Pt-Co | ≤15 |
| Specific gravity at 20 °C | 1.090–1.11 g/cm³ |
| Refractive index at 20 °C | 1.40–1.425 |
| Boiling point at 101.3 kPa | 190.2 °C |
| Open-cup flash point | 105 °C |
These figures help a procurement team compare the intended process requirements with the EGDA grade before ordering.
What are the main uses of ethylene glycol diacetate?
Ethylene glycol diacetate is used as a solvent in pharmaceutical applications, foundry core-binding, thermoplastic acrylic coatings, paints, printing inks, and fluorescent paints. It is also used as an organic ester curing agent for casting resin.
For resin and coating work, EGDA is used as a solvent for organic resins such as nitrocellulose and cellulose esters. Other applications include nitro spray paint, leather brighteners, and some acid-maintenance processes. A buyer should compare EGDA content, acidity, moisture, color, and refractive index with the requirements of the intended formulation.
How should ethylene glycol diacetate be stored and handled during transport?
Keep EGDA in a sealed container and protect it from water because it is easy to hydrolyze. During transport and storage, isolate it from open flames. Store it in a cool, dry place away from heat, moisture, sunlight, and rain.
EGDA has the general chemical properties of esters. In the presence of caustic soda and inorganic acids, it can be hydrolyzed to alcohols and acetic acids, so storage and process-area compatibility should be reviewed before use.
At receiving, check that containers remain sealed and dry before moving them into storage. For a coating or resin application, prepare the required grade, quantity, packaging format, and specification limits when requesting a quotation from Shijiazhuang Kunxiangda Technology Co., Ltd.
