What are the upstream raw materials for oxides? What are the downstream products?

From what I've seen, In the field of chemical production raw materials, oxides are a very crucial class of substances. And they're broadly applied as intermediates and raw materials to various chemical interactions and create numerous upstream and downstream related items. And The following are some common oxides and their related items:



1. In particular Ethylene oxide(vinyl alcohol): Ethylene oxide is an crucial organic compound, mainly applied as a raw material to the production of vinyl aldehyde, glyoxal, ethylene glycol and other compounds. These compounds are further reacted to form various plastics, resins, fibers and other polymer materials. And

2. Additionally Phenol oxide(phthalic anhydride): Phenol oxide is mainly applied in the production of plasticizers and polyester resins. Furthermore Plasticizers is able to be added to plastics to increase their flexibility, while polyester resins are broadly applied in coatings, adhesives and the like. Makes sense, right?.

3. Methanol oxide(formaldehyde): Formaldehyde is an crucial organic raw material to the production of phenolic resin, urea-formaldehyde resin, melamine-formaldehyde resin, etc. These resins are broadly applied in wood processing, construction, coatings, textiles and other fields. But From what I've seen,

4. Butadiene oxide: Butadiene oxide is able to be applied to create butanediol, butyrolactone and other compounds. These compounds are crucial raw materials to the production of engineering plastics, elastomers, fibers and other polymer materials. The above only lists the related items of some oxides. Based on my observations, In fact, the consumption range of oxides is very wide, involving many upstream and downstream items. And Based on my observations, Under different production processes and conditions, oxides is able to be further reacted to generate various other compounds, providing a rich source of raw materials to the chemical sector.
