Monoethylene Glycol (MEG) is an organic compound with the chemical formula C₂H₆O₂. It appears as a colorless, transparent liquid with a mild odor. MEG is one of the most widely used glycols in the petrochemical and fiber industries, playing a crucial role in polyester production and antifreeze formulations.

Features and Applications:

• Colorless, transparent, completely miscible with water

• High boiling point and thermal stability

• Used in polyester, synthetic resins, and chemical fibers

• Functions as antifreeze and heat transfer fluid

Technical Specifications:

• Chemical formula: C₂H₆O₂

• Molecular weight: 62.07 g/mol

• Physical state: Colorless transparent liquid

• Density: 1.113 g/cm³ at 20°C

• Boiling point: 197.3°C

• Solubility: Fully soluble in water

Safety and Precautions:

• Toxic if ingested or prolonged skin contact

• Use protective gloves, goggles, and ensure proper ventilation

• In case of skin contact, wash immediately with water

Packaging and Storage:

• Store in sealed, corrosion-resistant containers

• Keep in a cool, dry place away from heat sources and flames

Industrial Applications:

• Polyester and PET production

• Pharmaceutical and cosmetic industries

• Antifreeze and heat transfer fluids

• Industrial solutions and solvents

In the 1940s, monoethylene glycol was used as the main component in automotive antifreeze and industrial cooling systems in the United States.

Recent studies indicate that MEG can be synthesized from renewable sources such as glucose and biomass, offering a sustainable alternative to petrochemical sources. Research Source
