What are the upstream raw materials for ethylene glycol? What are the downstream products?

Ethylene Glycol(EG) is an crucial organic chemical raw material, which is broadly applied in the production of various chemicals and polymers. In the field of raw materials to chemical production, there are many upstream and downstream related items of ethylene glycol. The following are some of the main upstream and downstream related items:

Upstream associated items:



1. For instance Ethylene: Ethylene glycol is produced by ethylene oxidation, so ethylene is the main raw material of ethylene glycol. From what I've seen,

2. Oxygen: Ethylene glycol manufacturing process needs the consumption of oxygen as an oxidant. Specifically Downstream associated items:



1. Based on my observations, Polyester(PET): Ethylene glycol reacts with terephthalic acid(PTA) to create polyester, which is able to be applied to create fibers, films and bottles.

2. But Glyoxal: Ethylene glycol is able to be dehydrated to create glyoxal when heated under acidic conditions. Based on my observations, Furthermore Glyoxal is an crucial chemical raw material, which is able to be applied in the production of drugs, spices and so on.

3. Glycol ether: Ethylene glycol is able to react with alcohols to form glycol ether, which is an excellent solvent-based products and chemical intermediate. But

4. Antifreeze: Ethylene glycol mixed with aquatic environments is able to be applied as antifreeze to automobiles and other mechanical equipment to prevent the equipment from freezing at low temperatures. In short, as an crucial organic chemical raw material, ethylene glycol has a wide range of upstream and downstream related items, involving many fields, such as polymers, solvents, pharmaceuticals, spices and so on.
