In the field of raw materials for chemical production, there are many upstream and downstream related products of DAA (dimethyl adipate). The following are some of the main upstream and downstream associated products of DAA:

1. Upstream products:

(1) Adipic acid: Adipic acid is one of the main raw materials of DAA and is used to produce DAA. Adipic acid can be produced by the reaction of petrochemical raw materials such as benzene, nitric acid and hydrogen.

(2) Methanol: Methanol is another main raw material for DAA production, which reacts with adipic acid to form DAA. Methanol can be produced from fossil fuels such as natural gas and coal.

2. Downstream products:

(1) Nylon 66 salt: DAA can be used as an intermediate in the production of nylon 66 salt. Nylon 66 salt is a polymer monomer that can be used to produce nylon fibers, engineering plastics, etc.

(2) Caprolactam: DAA can be further processed into caprolactam, which is also an important polymer monomer for the production of nylon 6 fibers and engineering plastics.

(3) Plasticizer: DAA can be used as a plasticizer to improve the flexibility, ductility and low temperature toughness of plastics.

above is only a part of the upstream and downstream related products of DAA. In fact, DAA has a wide range of applications in the chemical industry, and there are many upstream and downstream related products. The specific products need to be determined according to different production processes and market needs.
