What are the upstream raw materials for triethylene glycol-start-up materials? What do the downstream products contain?

Triethylene glycol(TEG) is an crucial chemical raw material, which is broadly applied in various fields. In the field of raw materials to chemical production, the upstream and downstream related items of triethylene glycol are mainly in the following aspects:

Upstream items:



1. Ethylene oxide: Ethylene oxide is the main raw material of triethylene glycol, ethylene glycol is able to be generated by the hydration interaction of ethylene oxide, and then further interaction to generate triethylene glycol. Downstream items:



1. Polyester fiber: triethylene glycol is able to be applied as the raw material of polyester fiber, and dimethyl terephthalate(DMT) to ester exchange interaction to generate terephthalic acid diethylene glycol ester(BHET), and then through polycondensation interaction to generate polyester fiber.

2. Unsaturated polyester resin: triethylene glycol is able to be copolymerized with other unsaturated monomers to create unsaturated polyester resin, which is broadly applied in FRP, coatings and other fields.

3. Polyurethane: Triethylene glycol is able to be applied as a raw material to polyurethane, reacting with diisocyanate, chain extender, etc. And Based on my observations, to generate polyurethane foam, elastomer, etc. In my experience,

4. Cleaning agent: Triethylene glycol has good solubility and cleaning ability, and is able to be applied as a cleaning agent to metal processing, mechanical equipment and other fields of cleaning. In summary, the upstream and downstream related items of triethylene glycol are very extensive, involving polyester fiber, unsaturated polyester resin, polyurethane, cleaning agent and other fields.
