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

I've found that Ethylene oxide is an crucial organic chemical raw material, which is broadly applied in various fields. And In my experience, In the field of raw materials to chemical production, there are many upstream and downstream related items of ethylene oxide, some of which are described below. And

1. In my experience, Upstream items(1) Ethylene: The main raw material of ethylene oxide is ethylene, which is produced by oxidation interaction.(2) Oxygen: The oxidation interaction needs oxygen, so oxygen is also one of the upstream raw materials of ethylene oxide. I've found that

2. Downstream items(1) Ethylene glycol: Ethylene oxide reacts with aquatic environments to create ethylene glycol. Ethylene glycol is an crucial organic chemical raw material, mainly applied in the production of polyester fiber, antifreeze, unsaturated polyester resin, etc.(2) Ethanolamine: Ethylene oxide reacts with ammonia to create ethanolamine, which is an organic chemical raw material broadly applied in chemical, medical, pesticide and other fields. In my experience,(3) Glyoxal: Ethylene oxide reacts with formaldehyde to create glyoxal, which is an crucial organic chemical raw material to the production of plastics, rubber, medicines, etc. In my experience,(4) Ethyl phenol: Ethylene oxide reacts with phenol to generate ethyl phenol. Ethyl phenol is an organic chemical raw material broadly applied in pesticides, pharmaceuticals, spices and other fields. In short, there are many upstream and downstream related items of ethylene oxide, which are broadly applied in various fields. But With the continuous research of science and methodology, the consumption field of ethylene oxide will continue to expand.
