Mono Ethylene Glycol (MEG) 99.9%

Monoethylene glycol (MEG), also known as ethylene glycol or 1,2-ethanediol, is an organic compound with the chemical formula C2H6O2. It is a colorless, odorless, and slightly viscous liquid at room temperature.

Here are some key points about monoethylene glycol (MEG) with a purity of 99.9%:

1. Composition: Monoethylene glycol consists of two hydroxyl (OH) groups attached to a two-carbon chain. It is the simplest member of the glycol family, which includes diethylene glycol (DEG) and triethylene glycol (TEG).
2. Production: MEG is produced industrially by the hydration of ethylene oxide, which is derived from the oxidation of ethylene. The process typically involves the reaction of ethylene oxide with water in the presence of a catalyst to form monoethylene glycol.
3. Uses:
   • Antifreeze: One of the most common uses of MEG is as an antifreeze agent in automotive cooling systems and HVAC (heating, ventilation, and air conditioning) systems. It lowers the freezing point of water, preventing the formation of ice and protecting the system from damage in cold temperatures.
   • Polymer Production: MEG is a key ingredient in the production of polyester resins and fibers. It undergoes polymerization with terephthalic acid or dimethyl terephthalate to form polyethylene terephthalate (PET), which is used in the manufacture of plastic bottles, fibers for textiles, and packaging materials.
   • Solvent: MEG is utilized as a solvent in various applications, such as in the production of printing inks, dyes, and paints. It is also used as a solvent for natural gas dehydration and in the manufacture of electrolytic capacitors.
   • Humectant: MEG is used as a humectant in personal care products, cosmetics, and pharmaceuticals due to its ability to attract and retain moisture, helping to prevent products from drying out.
4. Physical Properties: MEG is highly soluble in water and many organic solvents. It has a relatively low freezing point (-12.9°C) and boiling point (197.3°C), making it suitable for use in antifreeze formulations and as a heat transfer fluid.
5. Safety Considerations: While MEG is generally considered safe for its intended industrial and commercial uses, it is toxic if ingested and can cause severe health effects. Proper safety precautions should be taken when handling MEG, and exposure should be minimized to prevent adverse health effects.
