Monoethylene glycol

Zarrin Fartak Chemical Company is offering monoethylene glycol and guarantees that the quality of this product is in accordance with the analysis report available on our website.

Monoethylene glycol (MEG) is a colorless, odorless, and hygroscopic liquid with the chemical formula C₂H₆O₂. It is a type of glycol and is commonly used in various industrial applications due to its properties as a solvent and antifreeze.

Applications:

۱٫ Antifreeze and Coolants: MEG is widely used in automotive antifreeze formulations, preventing freezing and lowering the boiling point of engine coolants.

۲٫ Polyester Production: It is a key raw material in the production of polyethylene terephthalate (PET), used in plastic bottles, textiles, and films.

۳٫ Solvent: MEG serves as a solvent in various applications, including paints, coatings, and inks.

۴٫ Dehydrating Agent: It is used to remove water from natural gas and other hydrocarbon streams.

۵٫ Chemical Intermediate: MEG is utilized in the production of various chemicals, such as resins, plasticizers, and surfactants.

Synthesis:
Monoethylene glycol can be synthesized through several methods, with the most common being:

۱٫ Ethylene Oxide Hydrolysis:

• Ethylene oxide (EO) is reacted with water in the presence of a catalyst (usually acidic or basic) to produce MEG. The reaction can be represented as follows:

C₂H₄O + H₂O → C₂H₆O₂

• This method is efficient and widely used in industrial settings.

۲٫ Direct Hydration of Ethylene:

• Ethylene can be directly hydrated using high temperatures and pressures, but this method is less common compared to the ethylene oxide hydrolysis method.

۳٫ Biotechnological Processes:

• Research is ongoing into using microbial processes for the production of MEG from renewable resources, though this is not yet a mainstream method.
