Ethylene glycol (EG) is a colorless, odorless, viscous liquid with hygroscopic and sweet taste. It has a wide range of uses in the field of chemical production raw materials, mainly used as solvents, reaction media and chemical raw materials.
The properties of
ethylene glycol
ethylene glycol has many unique properties, which makes it widely used in the field of chemical production raw materials. First of all, ethylene glycol is highly hygroscopic and can absorb moisture in the air. Secondly, it has a low viscosity and can be used as a solvent and reaction medium. In addition, ethylene glycol has a low vapor pressure and is not easily volatile, so it is often used as an antifreeze and coolant.
the use of
ethylene glycol
ethylene glycol in the chemical production of raw materials in the field of use is very extensive, the following is its main use:
1. solvent: ethylene glycol can be used as a solvent for many organic compounds, such as dyes, resins, paints and so on. Because of its low viscosity, good chemical stability and low toxicity, it is widely used in various chemical production.
2. reaction medium: ethylene glycol can be used as a reaction medium for many chemical reactions, such as esterification reaction, etherification reaction and so on. Due to its higher boiling point and lower vapor pressure, it can be used at higher temperatures and is less prone to volatile loss.
3. chemical raw materials: ethylene glycol can also be used as raw materials for many chemicals, such as ethylene glycol can be oxidized to produce glyoxal, which in turn generates oxalic acid (oxalic acid). Oxalic acid is a compound widely used in the chemical and pharmaceutical fields.
4. Antifreeze and coolant: Because ethylene glycol has a lower freezing point and a higher boiling point, it is widely used as an antifreeze and coolant. In the automotive industry, a mixture of ethylene glycol and water is often used as an engine coolant to prevent the engine from freezing at low temperatures.
In short, ethylene glycol as an important chemical production raw materials, has a wide range of uses. In the future chemical production, with the continuous progress of technology and the continuous expansion of application fields, the use of ethylene glycol will be further increased.
