Dibutyl phthalate (DBP) is a common plasticizer, widely used in plastics, rubber, paint, coatings and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of dibutyl phthalate mainly include the following categories:

upstream products:

1. Phthalic acid: Phthalic acid is one of the main raw materials for the production of dibutyl phthalate, which is usually obtained by oxidation of phthalic anhydride.
2. n-Butanol: n-Butanol is another main raw material for the production of dibutyl phthalate, which is usually produced by ethylene hydration method.

downstream products:

1. polyvinyl chloride (PVC): dibutyl phthalate as a plasticizer, can be widely used in PVC products, such as wire and cable, pipe, artificial leather and so on.
2. Nitrocellulose: Dibutyl phthalate can be used as a plasticizer for nitrocellulose for the production of coatings, inks and other products.
3. Natural rubber and synthetic rubber: Dibutyl phthalate can be used as a plasticizer for rubber to improve the processability and flexibility of rubber.
4. Other plastic products: dibutyl phthalate can also be used in other plastic products, such as foam, seals, etc.

In short, dibutyl phthalate has a wide range of upstream and downstream related products in the field of chemical production raw materials, which plays an important role in promoting the development of plastics, rubber, paint, coatings and other industries. However, it should be noted that dibutyl phthalate, as a chemical substance, has certain toxicity and harmfulness, and its dosage and safety need to be strictly controlled during use.
