Isophthalic acid (IPA) is an important organic chemical raw material, which is widely used in the production of various chemicals. The following are some major examples of upstream and downstream related products of isophthalic acid:

upstream products:

1. Benzene: Benzene is one of the main raw materials for the production of isophthalic acid, and isophthalic acid can be produced through oxidation reaction.

downstream products:

1. unsaturated polyester resin (UPR): isophthalic acid and ethylene glycol and other polyols reaction, can be made of unsaturated polyester resin, widely used in glass steel products, coatings, adhesives and other fields.
2. Polyester fiber: The reaction of isophthalic acid and ethylene glycol can produce polyester fiber, which is an important synthetic fiber and is widely used in textiles, clothing and other fields.
3. Plasticizer: Isophthalic acid can produce some plasticizers, such as dioctyl phthalate (DOP), which is used in plastic processing to increase the flexibility and plasticity of plastics.
4. Pharmaceutical intermediates: isophthalic acid can also be used as pharmaceutical intermediates for the production of some drugs, such as anti-inflammatory drugs, anti-cancer drugs.

In short, as an important organic chemical raw material, isophthalic acid has a wide range of upstream and downstream related products, involving many fields, such as coatings, textiles, medicine, etc.
