Diethylene Glycol (DEG) is an organic chemical compound from the glycol family, appearing as a clear, colorless liquid. It is produced by the reaction of ethylene oxide with water and is known for its high hygroscopicity and solubility in water and many polar solvents.

Features and Applications:

• Clear, odorless liquid with a high boiling point

• Moisture absorbent and stabilizer

• Solvent in the production of resins, paints, coatings, and industrial chemicals

• Intermediate in the synthesis of plastics and other chemical products

Technical Specifications:

• Chemical formula: C4H10O3

• Molecular weight: 106.12 g/mol

• Density: 1.118 g/cm³ (at 20°C)

• Boiling point: 245°C

• Melting point: -10°C

• Solubility: Soluble in water, alcohol, and many polar solvents

Safety and Hazards:

• Contact with skin and eyes may cause irritation

• Inhalation of concentrated vapors can be toxic

• Store in corrosion-resistant containers away from heat and sparks

Packaging and Storage:

• 200L steel or polyethylene drums

• Store in a dry, cool place, away from direct sunlight

• Follow MSDS guidelines

Industrial Applications:

• Production of resins, coatings, and industrial paints

• Intermediate in the synthesis of plastics and other chemicals

• Solvent in detergent and lubricant formulations

In the 1940s, Diethylene Glycol was used as an alternative to traditional glycols in lubricants and antifreeze production, enhancing product safety and stability.

Recent studies have shown that DEG can be used in the production of environmentally stable biodegradable resins. Source Link
