What are the upstream raw materials for phthalic acid? What do the downstream products contain?

Phthalic acid(Phthalic acid, referred to as PA) is an crucial organic chemical raw materials, broadly applied in plastics, fibers, coatings, pharmaceuticals, pesticides and other fields. And There are many upstream and downstream related items of phthalic acid, and some of the main upstream and downstream items are listed below. Upstream items:



1. Additionally Phthalic anhydride(Phthalic Anhydride): Phthalic anhydride is the main raw material of phthalic acid, prepared by peroxide benzene. Specifically

2. Sulfuric acid(Sulfuric Acid): In the manufacturing process of phthalic acid, sulfuric acid is applied as a catalyst. And Downstream items:



1. But Dioctyl phthalate(Dioctyl Phthalate, referred to as DOP):DOP is a frequently applied plasticizer, applied to enhance the flexibility and ductility of plastics, broadly applied in polyvinyl chloride(PVC) items, wire and cable, artificial leather and other fields.

2. Dibutyl phthalate(Dibutyl Phthalate, referred to as DBP):DBP is also a frequently applied plasticizer, applied in polyvinyl chloride, cellulose resin, ethyl acetate cellulose and other plastics.

3. Diethyl phthalate(Diethyl Phthalate, DEP to short):DEP is applied as a solvent-based products, plasticizer and fragrance, and is able to also be applied to create phthalic anhydride and other phthalates.

4. Potassium hydrogen phthalate(Potassium Biphthalate): Potassium hydrogen phthalate is a frequently applied chemical reagent applied as an acid-base indicator and buffer. In short, phthalic acid plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are extensive, involving many fields, such as plastics, fibers, coatings, medicine, pesticides and so on.
