Di Ethylene GLYCOL (DEG)

Specifications and Properties of Diethylene Glycol

Diethylene glycol (DEG) is a colorless, odorless liquid with high solubility in water, alcohol, ether, acetone, and ethylene glycol. It is miscible with many organic solvents and water at various concentrations. Due to its toxicity and flammability, proper safety precautions are required. DEG reacts with strong acids such as sulfuric, nitric, perchloric acids, and hydrogen peroxide.

Applications of Diethylene Glycol

1. Production of Saturated and Unsaturated Polyester Resins
DEG is widely used in the production of various resins, especially polyester resins.

2. Use as a Solvent
It serves as an effective solvent in paints, resins, and industrial gases.

3. Moisture Absorption
Used as a moisture absorber in moisture-sensitive products.

4. Coolants and Antifreeze
Applied in the production of antifreeze and heat transfer fluids.

5. Cosmetics and Personal Care
Used in creams, lotions, deodorants, and other care products.

6. Industrial Processes
Employed in the separation of aromatics, ink and dye production, lubricants, brake fluids, and more.

7. Specialty Products
Utilized in artificial fog, fire suppression systems, tobacco, and military applications.

Global Diethylene Glycol Market

The largest consumption market for DEG is the Asia-Pacific region, with China, India, and South Korea being major consumers. Demand growth in automotive, construction, and chemical industries drives market development. Europe is the second-largest market, particularly in textile and automotive sectors. North America, with its high natural gas production and automotive industry, also plays an important role. Iran is both a significant producer and consumer, with companies like Petro Aras being key glycol suppliers.

Market Opportunities and Advantages

• Growing demand in construction, coatings, and paints industries
• Extensive use as an intermediate in PET and polyester production
• Significant role in textile, plastic, and chemical industries
• Market growth in developing countries such as India and China

Challenges and Barriers

• Regulatory restrictions due to toxicity
• Volatility of raw material prices

Packaging and Transportation

DEG is typically supplied in 230 kg metal drums or IBC tanks. Containers should be corrosion-resistant, such as stainless steel or polyethylene. Despite its toxicity, DEG can be transported safely under flexible regulations via land, air, rail, and sea.

Safety and Storage

Storage Conditions:

• Store in a dry, cool, and well-ventilated area
• Avoid heat and moisture
• Use nitrogen blanketing and stainless steel tanks

Safety During Use:

• Avoid contact with skin, eyes, and clothing
