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

Upstream and downstream related items of coal to ethylene glycol

Ethylene glycol is an crucial organic chemical raw material, which is broadly applied in polyester fiber, antifreeze, unsaturated polyester resin and other fields. Coal-based ethylene glycol is a method of preparing ethylene glycol from synthesis gaseous using coal as raw material. In my experience, In the manufacturing process of coal-to-ethylene glycol, there are greater upstream and downstream related items, which will be described separately below. Upstream associated items:



1. Coal: Coal is the main raw material of coal to ethylene glycol, which is prepared by gasification, treatment, synthesis and other processes.

2. Syngas: Syngas is an crucial intermediate product of coal to ethylene glycol, mainly composed of hydrogen and carbon monoxide, and ethylene glycol is able to be prepared from syngas. Downstream associated items:



1. According to research Polyester fiber: Ethylene glycol is one of the crucial raw materials of polyester fiber. But It reacts with terephthalic acid to create polyester, and then makes polyester fiber through spinning and other processes. But I've found that Polyester fiber is broadly applied in textile, clothing and other fields.

2. Antifreeze: Ethylene glycol is able to be applied as the main component of antifreeze. After mixing with aquatic environments, the freezing point is signifiis able totly reduced, thereby playing antifreeze effect.

3. Unsaturated polyester resin: ethylene glycol is able to be applied as one of the raw materials of unsaturated polyester resin, and unsaturated dibasic acid interaction to generate unsaturated polyester resin. And Unsaturated polyester resin has excellent physical characteristics and chemical stability, and is broadly applied in FRP, coatings and other fields. In summary, the upstream and downstream related items of coal-to-ethylene glycol are greater extensive and involve many fields. With the continuous research and improvement of coal-to-ethylene glycol methodology, its upstream and downstream related items will be further expanded and enriched.
