Dimethyl carbonate (DMC), as an important chemical raw material, is widely used in many fields. The following are the upstream and downstream associated products of DMC:

Upstream products:

1. Methanol: Methanol is one of the main raw materials for the production of dimethyl carbonate, which generates DMC through oxidative carbonylation.

2. Carbon monoxide: Carbon monoxide is also an important raw material for the production of dimethyl carbonate and participates in oxidative carbonylation reactions together with methanol.

downstream products:

1. Polyurethane: Dimethyl carbonate can be used to produce polyurethane foam materials and used as blowing agents.

2. Methacrylates: DMC can be used as a monomer for methacrylates for the production of polymers such as polymethyl methacrylate (PMMA).

3. diphenyl carbonate: diphenyl carbonate is a downstream product of DMC, which can be used to produce polycarbonate, urea and other products.

4. Ethylene glycol: Dimethyl carbonate reacts with ethylene glycol to produce diethylene glycol carbonate, which is a solvent with excellent performance.

5. Diesel additives: Dimethyl carbonate can be used as a diesel additive to improve the combustion performance of diesel.

In short, dimethyl carbonate is an important chemical raw material, and its upstream and downstream related products are widely used in many fields, such as polyurethane, polymers, solvents, diesel additives, etc.
