What are the upstream raw materials for isophthalic acid? What are the downstream products?

From what I've seen, Isophthalic acid(IPA) is an crucial organic chemical raw material, which is broadly applied in the production of various chemicals. But The following are some key examples of isophthalic acid upstream and downstream associated items:

Upstream items:



1. Benzene: Benzene is one of the main raw materials to the production of isophthalic acid, which is able to be produced by oxidation interaction. Downstream items:



1. But Unsaturated polyester resin(UPR): isophthalic acid reacts with glycol and other polyols to create unsaturated polyester resin, which is broadly applied in FRP items, coatings, adhesives and other fields.

2. Based on my observations, Polyester fiber: The interaction of isophthalic acid and ethylene glycol is able to create polyester fiber, which is an crucial synthetic fiber and is broadly applied in textiles, clothing and other fields.

3. But Plasticizers: Isophthalic acid is able to create some plasticizers, such as dioctyl phthalate(DOP), etc., which are applied in plastic processing to increase the flexibility and plasticity of plastics. And

4. And medical intermediates: isophthalic acid is able to also be applied as medical intermediates to the production of some drugs, such as anti-inflammatory drugs, anti-is able tocer drugs. In short, as an crucial organic chemical raw material, isophthalic acid has a wide range of upstream and downstream related items, involving many fields, such as coatings, textiles, medicine and so on.
