[Chemical Knowledge]:What are the upstream raw materials for triethylene glycol? What are the downstream products?

Triethylene Glycol (TEG) is a kind of chemical raw material with wide application value. In the chemical industry chain, there are many upstream and downstream related products of triethylene glycol, and this article will introduce its main upstream and downstream products respectively.

upstream products:

1. Ethylene glycol (Ethylene Glycol, referred to as EG): Ethylene glycol is the main raw material for the production of triethylene glycol, which can be produced by catalytic oxidation and hydrolysis of ethylene glycol.
2. Ethylene oxide (Ethylene, EO): Ethylene oxide is also an important raw material in the production process of triethylene glycol. Through the hydration reaction of ethylene oxide, ethylene glycol can be obtained, and then further react to generate triethylene glycol.

downstream products:

1. Coating: Triethylene glycol can be used as a solvent and humectant in the coating to improve the performance and application effect of the coating.
2. Resin: Triethylene glycol can be used to produce various resins, such as phenolic resin, epoxy resin, etc., to improve the toughness and water resistance of the resin.
3. Coolant: Triethylene glycol has good antifreeze performance and can be used as a coolant for automobiles, aviation and other engines.
4. Polyester fiber: Triethylene glycol can be used to produce polyester fiber to improve the softness and elasticity of the fiber.
5. Cleaning agent: Triethylene glycol can be used as the main component of the cleaning agent for cleaning various metal surfaces and parts.

In summary, triethylene glycol has a wide range of application value in the field of chemical production raw materials, and its upstream and downstream related products are numerous, involving coatings, resins, coolants, polyester fibers, cleaning agents and other fields.
