What is Mono Ethylene Glycol?
Mono ethylene glycol (CH2OH) is an organic compound with the formula 2. It is mainly used for two purposes. The first of these is the production of polyester fiber and the other is its use as a raw material for antifreeze formulations. It is an odorless, colorless, sweet-tasting, viscous liquid.
How is Mono Ethylene Glycol produced?
Ethylene glycol is produced from ethylene (ethene) with intermediate ethylene oxide. Ethylene oxide reacts with water to produce ethylene glycol according to the chemical equation:
C2H4O + H2O → HO − CH2CH2 − OH
Bu reaksiyon, asitler veya bazlar tarafından katalize edilebilir veya yüksek sıcaklıklar altında nötr pH’ta meydana gelebilir. En yüksek etilen glikol verimleri, asidik veya nötr pH’ta, çok fazla su ile oluşur. Bu koşullar altında, %90 etilen glikol verimleri elde edilebilir. Başlıca yan ürünler, oligomerler, dietilen glikol, trietilen glikol ve tetraetilen glikoldür. Bu oligomerlerin ve suyun ayrılması enerji yoğundur. Yılda yaklaşık 6,7 milyon ton üretilmektedir.

What are the usage areas (processes) of Mono Ethylene Glycol?
Etilen glikol esas olarak antifriz formülasyonlarında (%50) ve polietilen tereftalat (PET) (%40) gibi polyesterlerin üretiminde hammadde olarak kullanılır.
- The primary use of ethylene glycol is as a vehicle for convective heat transfer in automobiles and liquid-cooled computers. Ethylene glycol is also commonly used as a refrigerant for chilled water air conditioning systems. Here it places the chiller or air handlers outside or the water needs to cool to below freezing.
- In geothermal heating/cooling systems, ethylene glycol is the fluid that carries the heat using a geothermal heat pump. Ethylene glycol gains energy from the source (lake, ocean, water well) or dissipates heat to the sink, depending on whether the system is used for heating or cooling.
- Etilen glikol antifriz olarak kullanılır. Saf etilen glikol yaklaşık -12 ° C’de (10,4 ° F) donar, ancak suyla karıştırıldığında karışım daha düşük bir sıcaklıkta donar. Örneğin, %60 etilen glikol ve%40 su karışımı -45°C’de (-49°F) donar. Dietilen glikol de benzer şekilde davranır. Bazı karışımların donma noktası alçalması, çözeltilerin bir kolligatif özelliği olarak açıklanabilir, ancak örnek gibi oldukça konsantre karışımlarda, moleküller arası kuvvetlerin etkisine bağlı olarak ideal çözelti davranışından sapmalar beklenir.
- There is a difference in the mixing ratio depending on whether it is ethylene glycol or propylene glycol. Mixing ratios for ethylene glycol are typically 30/70 and 35/65, while mixing ratios for propylene glycol are typically 35/65 and 40/60. It is important that the mixture is frost-proof at the lowest operating temperature.
- In the plastics industry, ethylene glycol is an important precursor for polyester fibers and resins. Polyethylene terephthalate, which is used to make plastic bottles for soft drinks, is prepared from ethylene glycol.
- Ethylene glycol is used in the natural gas industry in much the same way as triethylene glycol (TEG) to remove water vapor from natural gas before further processing.
- Due to its high boiling point and affinity for water, ethylene glycol is a useful desiccant. Ethylene glycol is widely used to prevent the formation of natural gas hydrates in long multiphase pipelines transporting natural gas from remote gas fields to a gas processing plant. Ethylene glycol can be recovered from natural gas and reused as an inhibitor after purification, which removes water and inorganic salts.
- Ethylene glycol facilitates the application of the paint. For this reason, ethylene glycol is used as a liquid transfer agent in this sector.
- It can be used in the production of synthetic selective, lubricants, solvents, surfactants, softeners, explosives and humectants.
- In the pharmaceutical and tanning industry, glycol can be used instead of glycerol as a solvent and hydration agent.
- By adding it to the hydraulic fluid, ethylene glycol can be used to prevent the system from melting the oil-based hydraulic fluid on the rubber.
