What Is the CAS Number of Ethylene Glycol (CAS 107-21-1)?
The CAS number of Ethylene Glycol is 107-21-1. This unique identifier is widely used by chemical manufacturers, suppliers, and international buyers.
Basic Information of Ethylene Glycol
This organic compound is highly toxic. It is also known as Ethane-1,2-diol or Monoethylene glycol. It has no smell and is viscous. It is colourless and has a sweet taste. It appears as a clear, colourless, liquid. It is widely used as an antifreeze and a raw material in the plastic industry. Ethylene Glycol is produced when ethylene oxide reacts with water.
What Is Ethylene Glycol MEG Used for?
Antifreeze Coolant
Ethylene glycol's properties make it an ideal antifreeze coolant ingredient. Its low freezing point (down to -12.9°C) and high boiling point (up to 197.6°C) protect engines against overheating and freezing in cold weather. It efficiently transfers heat, ensuring optimal engine performance.
Solvent and Humectant
Ethylene glycol's low volatility and high boiling point make it a useful solvent in various industries, including pharmaceuticals, cosmetics, and textile manufacturing. It acts as a humectant in skincare products, maintaining moisture and preventing drying or cracking.
Heat Transfer Fluid
Ethylene glycol's excellent thermal conductivity and stability make it a suitable heat transfer fluid in diverse heating and cooling systems. Its ability to retain heat makes it suitable for solar panels, HVAC systems, and geothermal heat pumps.
Chemical Intermediate
Ethylene glycol is a vital intermediate in the production of polyester fibres and plastics like polyethylene terephthalate (PET). It reacts with terephthalic acid or dimethyl terephthalate to produce PET, widely used in beverage bottles, clothing fibres, and packaging materials.
