Diethyl carbonate (Diethyl Carbonate, DEC) is an important organic chemical raw material, which is widely used in medicine, pesticide, plastic, battery electrolyte and other fields. In the field of chemical production raw materials, there are many upstream and downstream related products of diethyl carbonate, some of which are described in detail below.

Upstream Associated Products:

1. Ethanol: The production of diethyl carbonate mainly takes ethanol as raw material and is produced by esterification reaction. Therefore, the price and availability of ethanol have a large impact on the production of diethyl carbonate.
2. Carbon dioxide: In the production process of diethyl carbonate, carbon dioxide needs to be used as a raw material to react with ethanol to produce diethyl carbonate.

downstream associated products:

1. urea: diethyl carbonate can be used as one of the raw materials for the production of urea, through the reaction with ammonia to produce ethyl carbamate, and then further pyrolysis to produce urea.
2. dimethyl carbonate: diethyl carbonate and methanol can occur transesterification reaction of dimethyl carbonate, which is an important solvent and chemical raw materials.
3. Ethephon: Diethyl carbonate can be used as a raw material for the production of ethephon, a widely used plant growth regulator.
4. Battery electrolyte: Diethyl carbonate is a commonly used battery electrolyte solvent with high dielectric constant and good electrochemical stability.

From the above introduction, it can be seen that there are many upstream and downstream related products of diethyl carbonate, and its application fields are extensive. At the same time, the production and use of diethyl carbonate also need to pay attention to safety and environmental protection issues to promote its sustainable development.

In conclusion, as an important organic chemical raw material, diethyl carbonate has broad application prospects in the field of chemical production raw materials. The diversity of its upstream and downstream related products also provides more options and possibilities for the production and use of diethyl carbonate.
