Diethylene Glycol (DEG) is a versatile organic compound with a wide array of industrial applications. Understanding its properties, appropriate uses, and safe handling practices is essential for anyone involved in its procurement or utilization. This guide provides a thorough overview for procurement managers and R&D scientists.

Physical and Chemical Properties of DEG
Diethylene Glycol, identified by CAS number 111-46-6, is characterized by its appearance as a colorless, transparent, and viscous liquid. Key properties include:

  • High Boiling Point: Approximately 245 °C, making it suitable for high-temperature processes.
  • Hygroscopicity: It readily absorbs moisture from the air.
  • Solubility: Highly soluble in water and many organic solvents.
  • Chemical Reactivity: Contains two hydroxyl groups and ether linkages, enabling it to undergo esterification and etherification reactions.

Industrial Applications of Diethylene Glycol
DEG's unique combination of properties makes it valuable across several industries:

  • Solvent: Used in coatings, inks, and as an extraction solvent.
  • Antifreeze Component: Blended with other glycols to lower freezing points and raise boiling points in industrial coolants.
  • Chemical Intermediate: Serves as a raw material for plasticizers, resins, and other specialty chemicals.
  • Textile Applications: Acts as a dye solvent and fiber absorbent to improve dyeing uniformity.
  • Natural Gas Dehydration: Used to remove water vapor from natural gas streams.

Safe Handling and Toxicity Information
It is critically important to note that Diethylene Glycol is toxic, particularly to the kidneys and nervous system. Therefore, it is strictly prohibited from use in food, beverages, pharmaceuticals, cosmetics, or any application involving direct human contact. Always handle DEG with appropriate personal protective equipment (PPE), including chemical-resistant gloves, safety goggles, and adequate ventilation. Refer to the Material Safety Data Sheet (MSDS) for detailed safety protocols, storage recommendations (cool, dry, well-ventilated area, away from oxidizers), and emergency procedures.
