Description

Diethylene Glycol (DEG) is a versatile, colorless liquid that is widely utilized in various industrial applications due to its unique chemical properties. As a member of the glycol family, it is characterized by its low volatility, low viscosity, and hygroscopic nature, making it an essential component in many formulations.

  • Molecular Formula: C44​H101​0O33​
  • Boiling Point: 245 °C
  • Density: Approximately 1.118 g/cm³
  • Solubility: Completely miscible with water and many organic solvents

DEG exhibits a higher boiling point and viscosity compared to its counterpart, ethylene glycol, which allows for specialized applications where these properties are advantageous. It possesses hydroxyl groups that enable it to engage in various chemical reactions, leading to the production of numerous derivatives such as ethers, esters, and amines.

Diethylene Glycol is primarily produced through the partial hydrolysis of ethylene oxide. This process can be optimized to yield high purity levels suitable for industrial applications. DEG is often co-produced with other glycols such as monoethylene glycol (MEG) and triethylene glycol (TEG), allowing for efficient resource utilization within chemical manufacturing processes.

Diethylene Glycol is employed across multiple sectors, including:

  • Industrial Solvents: Its excellent solvent properties make DEG suitable for use in cleaners and adhesives.
  • Heat Transfer Fluids: DEG is utilized in systems requiring efficient heat transfer due to its thermal stability.
  • Chemical Intermediate: It serves as a precursor in the production of unsaturated polyester resins (UPRs) and polyurethanes, which are critical in manufacturing durable materials.
  • Cement Processing: DEG is used to enhance the properties of cement mixtures.
  • Pharmaceuticals: While DEG has been historically associated with toxicological risks when improperly used in medicinal products, it remains a subject of regulatory scrutiny due to past incidents of contamination.

  • Toxicity: DEG is toxic if ingested, inhaled, or absorbed through the skin. Proper safety measures, including the use of personal protective equipment, should be followed during handling.
  • Storage: Store in a cool, dry, and well-ventilated area away from incompatible substances. Keep the container tightly closed when not in use.

  • Versatility: DEG’s wide range of applications across multiple industries highlights its versatility.
  • Solvency: Its ability to dissolve a variety of substances makes it a preferred solvent in many processes.
  • Stability: DEG is chemically stable under normal conditions, ensuring long-term efficacy in its applications.
