Dioctyl phthalate (DOP) is a common chemical raw material, widely used in plastics, rubber, paint, coatings and other fields. Among the upstream and downstream related products of DOP, there are mainly the following aspects:

upstream related products:

1. Phthalic anhydride: Phthalic anhydride is one of the main raw materials of DOP and is used to produce DOP.

2. Octanol: Octanol is another major raw material for DOP, which reacts with phthalic anhydride to produce DOP.

downstream related products:

1. Polyvinyl chloride (PVC):DOP is one of the main plasticizers of PVC, which can improve its flexibility, ductility and processability.

2. rubber products: DOP can be used in rubber products to improve the processing performance and elasticity of rubber.

3. Paints and coatings: DOP can be used as a solvent and plasticizer in paints and coatings to improve the flexibility and durability of coatings.

4. Artificial leather: DOP can be used in the production of artificial leather to increase the softness and elasticity of artificial leather.

In short, the upstream and downstream related products of dioctyl phthalate (DOP) are very extensive, involving many fields, such as plastics, rubber, paint, coatings, etc.
