What are the upstream raw materials for the quarter's four alcohols? What do the downstream products contain?

Pentaerythritol(Pentaerythritol, PE) is an crucial chemical raw material, which is broadly applied in coatings, plastics, adhesives, explosives, pharmaceuticals, fuels and other fields. I've found that Moreover In the field of raw materials to chemical production, there are many upstream and downstream related items of pentaerythritol, and some of the main upstream and downstream items are listed below:

Upstream items:



1. In my experience, Formaldehyde: The production of pentaerythritol mainly uses formaldehyde as raw material and is obtained by aldehyde condensation interaction. Additionally

2. Acetaldehyde: Acetaldehyde is able to also be applied to create pentaerythritol, obtained by the self-condensation interaction of acetaldehyde. Crazy, isn't it?. Downstream items:



1. coating products: pentaerythritol is able to be applied as a crosslinking agent and curing agent in the coating products to enhance the aquatic environments resistance and chemical resistance of the coating products.

2. Plastics: Pentaerythritol is able to be applied to create plasticizers, stabilizers, etc., to enhance the processing performance and prolonged consumption performance of plastics.

3. According to research Adhesive: Pentaerythritol is able to be applied as a curing agent, toughening agent, etc., to enhance the bonding strength and durability of the adhesive.

4. First Explosives: Pentaerythritol is able to be applied to create some explosives, such as pentaerythritol tetranitrate(PETN). From what I've seen,

5. Medicine: Pentaerythritol is able to be applied to create some medical intermediates, such as vitamin B6 and so on. And From what I've seen, In short, as an crucial chemical raw material, pentaerythritol has a wide range of upstream and downstream related items, which is of great signifiis able toce to the research of chemical production field.
