Glycol

MEG, DEG, TEG

Glycols are a group of organic compounds containing two hydroxyl groups and are widely used in various industries as antifreeze agents, solvents, desiccants, and chemical intermediates. The three most common types include Monoethylene Glycol (MEG), Diethylene Glycol (DEG), and Triethylene Glycol (TEG), each with its own specific properties and applications. These substances are colorless, odorless, and hygroscopic, and are fully miscible with water and many solvents.

About the Product

  • Monoethylene glycol (MEG)

    Monoethylene Glycol is a colorless, viscous liquid primarily used as the main base for antifreeze and coolant fluids in industrial and automotive engines. It is also widely used in the petrochemical industry as a raw material in the production of polyesters and PET resins.

  • Diethylene glycol (DEG)

    Diethylene Glycol (DEG) is more viscous than MEG and has a higher moisture absorption capacity. It is used as a solvent in the production of resins, printing inks, lubricants, and also in industrial drying processes.

  • Triethylene Glycol (TEG)

    Triethylene Glycol, with the highest boiling point among the three types, is primarily used in the oil and gas industry for natural gas dehydration. It is also applied as a disinfectant and stabilizer in certain pharmaceutical and healthcare formulations.

Applications of Glycol

  • Antifreeze and Coolant Fluids

    Monoethylene Glycol is the primary base for antifreeze fluids and, due to its low freezing point and excellent heat transfer capability, is widely used in cooling and heating systems.

  • Moisture Absorption in the Oil and Gas Industry

    Triethylene Glycol is used in the natural gas dehydration process, where it absorbs moisture from the gas stream to prevent hydrate formation and corrosion in pipelines.

  • Polyester and PET Resin Production

    Monoethylene Glycol is used as a raw material in the production of polyethylene terephthalate (PET) and polyester fibers, playing a key role in the textile and packaging industries.

  • Solvent in Industrial Formulations

    DEG and TEG are used as effective solvents in resin formulations, inks, and certain chemical products that require high stability and water miscibility.

FAQ About Glycol

Are glycols only available for export purposes?

No, glycols are also used in domestic factories.

What is the main export destination for glycols?

Glycols are mainly exported to Iran's neighboring countries, including Turkey, Iraq, or Syria, and CIS countries.

Is monoethylene glycol alone a substitute for antifreeze?

No, this substance is one of the main raw materials for the production of ice.

Is it possible to substitute one type of glycol for another?

Yes, in some cases it is possible to use MEG instead of DEG.
