Use of Mono Ethylene Glycol
MEG is most commonly used as a chemical intermediate in the manufacture of polyester resins and textile fibers. Polyester fiber is widely used in the textile industry for making clothing and household textiles. Polyester resin is mainly used to produce plastic bottles and food packaging containers. MEG (monoethylene glycol) is also used as an antifreeze agent, coolant, and solvent. It is especially common in automotive coolant applications due to its excellent antifreeze and thermal conductivity properties. In natural gas dehydration processes, MEG is also used to remove moisture from gas and prevent the formation of hydrates.

Physical Properties of MEG
MEG (mono ethylene glycol) is a colorless, odorless, and viscous liquid with a high boiling point and low volatility. Its chemical formula is C₂H₆O₂, with a molecular weight of 62.07 g/mol. It has a melting point of -12.9°C and a boiling point of 197.3°C. MEG glycol is highly soluble in water and can be mixed with water in any ratio. It is also soluble in various organic solvents such as ethanol, acetone, and ether. These physical properties make meg highly versatile and practical for a wide range of industrial applications.
Chemical Properties of MEG
MEG mono ethylene glycol has a diol structure, meaning it contains two hydroxyl (-OH) groups within its molecule. This structure gives it the typical chemical characteristics of alcohols and allows it to undergo various chemical reactions. For example, it can react with acids to form esters and with aldehydes to form acetals. It can also undergo oxidation to produce glyoxal or oxalic acid. Under high temperatures, meg can undergo dehydration reactions to form diethylene glycol or ethylene oxide. These chemical reactivity features make meg glycol valuable in chemical manufacturing.
How is Meg produced through our meg plant?
There are two main methods for producing meg mono ethylene glycol: the petrochemical method and the biomass-based method. The petrochemical method is currently the most widely used. It involves the oxidation of ethylene to produce ethylene oxide, which is then hydrolyzed to generate meg. This process is efficient and well-established. Specifically, ethylene reacts with oxygen in the presence of a silver catalyst to form ethylene oxide, which then reacts with water to produce MEG. Industrial production includes separation and purification steps to obtain high-purity meg glycol.
