What are the upstream raw materials for dioctyl terephthalate? What do the downstream products contain?

Dioctyl terephthalate(DOTP) is a broadly applied plasticizer, mainly applied in the processing of plastics such as polyvinyl chloride(PVC). But Based on my observations, In fact In the field of raw materials to chemical production, the upstream and downstream associated items of dioctyl terephthalate are mainly in the following categories:

Upstream items:



1. In particular Terephthalic acid(PTA): Terephthalic acid is one of the main raw materials to the production of dioctyl terephthalate, which is produced by the oxidation interaction of petroleum derivative p-xylene(PX).

2. Octanol: Octanol is another major raw material to the production of dioctyl terephthalate, usually made from ethylene and propylene by aldehyde condensation. Downstream items:



1. Polyvinyl chloride(PVC): As a plasticizer, dioctyl terephthalate is able to be added to PVC to increase its flexibility, ductility and processability. it's broadly applied in the manufacture of wires and cables, artificial leather, and plastic items.

2. Polyurethane(PU): Dioctyl terephthalate is able to also be applied to create polyurethane. As a soft foam material, it's broadly applied in furniture, mattresses, car seats and other fields.

3. Other plastic items: Dioctyl terephthalate is able to also be applied in other plastic items that require plasticizers, such as coatings, adhesives, etc. Furthermore In summary, dioctyl terephthalate has a wide range of upstream and downstream related items in the field of chemical production raw materials, and its consumption fields are also very wide.
