The properties and uses of ethylene glycol play an important role in the field of chemical production raw materials. Ethylene glycol is a colorless, tasteless, viscous liquid with many unique properties, so it is widely used in chemical, pharmaceutical, food and other industries. This article will detail the properties and uses of ethylene glycol.
1. The nature of ethylene glycol
1. Physical properties: Ethylene glycol is a colorless and transparent viscous liquid with a high boiling point and melting point, and a low vapor pressure, so it is easy to volatilize. Ethylene glycol is miscible with water, ethanol and other solvents, and has good solubility.
2. chemical properties: ethylene glycol molecule contains two hydroxyl groups, with strong hydrophilicity, can react with acid, alkali, ester and other compounds. Ethylene glycol has strong reducibility and is easily oxidized to oxalic acid (oxalic acid).
2. the use of ethylene glycol
1. antifreeze: ethylene glycol as an excellent antifreeze, widely used in automobiles, aviation, ships and other transportation fields. Due to the low freezing point of ethylene glycol, the freezing point of the liquid can be reduced, thereby preventing the equipment from freezing in a low temperature environment and ensuring the normal operation of the equipment.
2. solvent: ethylene glycol has good solubility, can be used as a solvent for the production of paint, ink and other products. In addition, ethylene glycol can also be used in the production of cleaning agents, paint remover and other chemicals.
3. Plasticizer: Ethylene glycol can be used as a plasticizer in the plastic industry to improve the flexibility, impact resistance and processability of plastics.
4. wetting agent: ethylene glycol has good hydrophilicity, can be used as a wetting agent for textiles, leather and other materials in the production, improve the moisture absorption and softness of materials.
5. pharmaceutical intermediates: ethylene glycol can be used in the production of pharmaceutical intermediates, such as for the production of antibiotics, vitamins and other drugs.
In short, ethylene glycol is widely used in the field of chemical production raw materials and plays an important role in improving product quality and production efficiency. With the continuous development of science and technology, the application field of ethylene glycol will continue to expand.
