Mono Ethylene Glycol-MEG

What is Diethylene Glycol (DEG)?

Diethylene Glycol (DEG) is a colorless, odorless, and hygroscopic liquid renowned for its exceptional solubility, thermal stability, and low volatility. As a member of the dihydroxy alcohol family, DEG’s chemical stability and versatility make it indispensable in industries ranging from polymer manufacturing to pharmaceuticals. Its high boiling point (245°C) and ability to absorb moisture from the air further enhance its utility in heat transfer fluids, antifreeze, and coatings.

Key Properties of Diethylene Glycol (DEG)

Understanding the physical and chemical properties of Diethylene Glycol is critical for optimizing its industrial applications:

  • Chemical Formula: C₄H₁₀O₃
  • Boiling Point: 245°C (473°F)
  • Melting Point: -10°C (14°F)
  • Density: 1.118 g/cm³
  • Viscosity: Higher than ethylene glycol, ensuring superior flow control.
  • Solubility: Fully miscible with water, alcohol, acetone, and other glycols.
  • Flash Point: 143°C (289°F), making it safer for high-temperature processes.

Why These Properties Matter:
DEG’s hygroscopic nature and thermal resilience enable its use in moisture-sensitive applications like natural gas dehydration and heat transfer systems. Its low volatility also minimizes evaporation losses in coatings and resins.

Industrial Grades of Diethylene Glycol

Different grades of Diethylene Glycol cater to diverse industrial needs:

  1. Industrial Grade DEG: Cost-effective for adhesives, resins, and bulk chemical synthesis.
  2. Technical Grade DEG: High-purity formulations for antifreeze, lubricants, and precision cleaners.
  3. USP Grade DEG: Pharmaceutical and cosmetic compliance with ultra-low impurities.
  4. Polyester Grade DEG: Optimized for PET plastics, textiles, and packaging materials.
  5. Low-Moisture Grade DEG: Ideal for hydraulic fluids and moisture-sensitive engineering systems.

Top 10 Applications of Diethylene Glycol

DEG is a cornerstone in multiple industries due to its adaptability:

  1. Paints & Coatings: Acts as a solvent to improve flow, adhesion, and drying times.
  2. Polymer Production: Enhances flexibility in polyurethanes and polyester resins.
  3. Cosmetics: Serves as a humectant in lotions and shampoos for moisture retention.
  4. Heat Transfer Fluids: Prevents freezing in industrial coolants and de-icing solutions.
  5. Natural Gas Dehydration: Removes moisture to prevent pipeline corrosion.
  6. Plasticizers: Strengthens paper and textile fibers.
  7. Hydraulic & Brake Fluids: Ensures performance under extreme temperatures.
  8. Lubricants: Reduces friction in metalworking and machining.
  9. Resin Production: Improves durability in industrial coatings.
  10. Pharmaceuticals: Used in controlled quantities for drug formulations.

How is Diethylene Glycol Produced?

Diethylene Glycol is a byproduct of mono-ethylene glycol (MEG) production:

  1. Ethylene Oxidation: Ethylene gas reacts with oxygen over a silver catalyst to form ethylene oxide.
  2. Hydration: Ethylene oxide is hydrolyzed with water, yielding a mixture of MEG, DEG, and triethylene glycol (TEG).
  3. Distillation: DEG is separated via fractional distillation due to its intermediate boiling point.

Safety Guidelines for Handling Diethylene Glycol

While Diethylene Glycol is invaluable industrially, its toxicity demands strict safety measures:

  • PPE Requirements: Nitrile gloves, chemical goggles, and respirators for vapor protection.
  • Ventilation: Use fume hoods to avoid inhalation risks.
  • Storage: Keep in labeled, sealed containers away from heat and incompatible materials.
  • Toxicity Awareness: Ingestion or prolonged exposure can cause kidney/liver damage. Immediate medical attention is critical if symptoms arise.

Packaging Solutions for Diethylene Glycol

DEG is packaged based on volume and application requirements:

  • Small-Scale: HDPE jerrycans (25L) or plastic drums (200L).
  • Bulk Shipments: IBC tanks (1000L) or stainless steel tanker trucks.
  • Compliance: All containers feature hazard labels and safety data sheets.
