Physical & Chemical Properties
DEG is a colorless, transparent and viscous liquid with practically no odor, slightly sweet taste and strong hygroscopicity. It is miscible with water, ethanol, ether, acetone and most polar organic solvents, and has stable chemical properties under normal conditions.
Key physical and chemical parameters are detailed in the specification table below, including melting point, boiling point, density, refractive index and other important indicators, which meet the requirements of premium industrial grade.
Main Uses
DEG is a basic petrochemical raw material with a wide range of applications in various industries:
- Gas Dehydration: Used as a dehydrating agent for natural gas, coal gas and other gases to remove moisture in the gas and ensure the normal operation of the gas transmission system.
- Solvent: Applied as a solvent in coatings, inks, adhesives, dyes and daily chemical products, with good solubility and compatibility.
- Chemical Intermediate: Used in the synthesis of ethylene glycol ether, plasticizer, polyester resin, polyurethane and other fine chemicals.
- Other Uses: Also used in brake fluid, antifreeze, textile softener, aromatic hydrocarbon extraction, pharmaceutical excipients and other fields, widely used in chemical, daily chemical, energy and pharmaceutical industries.
Packaging & Storage
Packaging Method
Lab Grade: 1L, 5L, 25L sealed plastic bottles, suitable for laboratory use and small-batch sampling.
Industrial Grade: 200L galvanized iron drum/HDPE drum, 1000L IBC tote, 20000L ISO tank, all adopt sealed moisture-proof packaging to prevent moisture absorption and contamination.
Storage Method
Store in a cool, dry and well-ventilated warehouse, the storage temperature should be controlled between 5-30℃. Keep the package tightly sealed to prevent moisture absorption and volatilization. Away from fire, heat source and strong oxidants, avoid contact with copper, zinc and other alloys. The shelf life is 24 months under standard sealed storage conditions.
