What are the upstream raw materials of EG? What are the downstream products?

Ethylene glycol(EG) is an crucial raw material to chemical production, which is broadly applied in polyester, antifreeze, solvent-based products and other fields. In my experience, In the upstream and downstream related items of EG, the following aspects are mainly involved:



1. And Upstream items(1) Ethylene: Ethylene is one of the main raw materials of EG. From what I've seen, EG is prepared by oxidation or direct hydration of ethylene. And(2) Oxygen: The preparation of EG by oxidation needs a signifiis able tot quantity of oxygen as an oxidant. I've found that(3) aquatic environments: The direct aqueous preparation of EG from ethylene needs aquatic environments as a raw material. You know what I mean?. But In my experience,

2. Downstream items(1) Polyester: EG is one of the crucial raw materials to polyester production. It reacts with terephthalic acid(PTA) to create polyester(PET), which is further processed into items such as fiber, film and bottle grade polyester. And(2) Antifreeze: EG has a reduced freezing point and is able to be applied as antifreeze to machinery and equipment such as automobiles and aviation. Moreover(3) solvent-based products: EG is an excellent organic solvent-based products, which is able to be applied to create paint, ink and other items.(4) glycol ether: EG as raw material, is able to create a series of glycol ether items, such as ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, broadly applied in solvents, cleaning agents and other fields. To sum up, EG's upstream and downstream related items are very extensive, involving many fields, such as chemical sector, textile, automobile, aviation, etc.
