Carbon dioxide has a wide range of applications in the field of chemical production raw materials. The following are some upstream and downstream related products related to carbon dioxide:

1. Upstream products:

(1) Limestone: Limestone is one of the main carbon dioxide emission sources, and a large amount of carbon dioxide gas can be produced by calcining limestone.

(2) Natural gas: The main component of natural gas is methane, and a large amount of carbon dioxide gas is produced during combustion.

(3) Coal: As a fossil fuel, coal also produces a large amount of carbon dioxide gas when burned.

2. Downstream products:

(1) Urea: Carbon dioxide can react with ammonia to form urea, which is an important nitrogen fertilizer and is widely used in agricultural production.

(2) Sodium carbonate: Carbon dioxide can react with sodium hydroxide to generate sodium carbonate, also known as soda ash, which is widely used in glass, paper, detergent and other fields.

(3) Dimethyl carbonate: Carbon dioxide can react with methanol to generate dimethyl carbonate, which is an important organic solvent and chemical raw material.

(4) Degradable plastics: Carbon dioxide can react with epoxides to generate cyclic carbonates, which can further produce degradable plastics. This is an environmentally friendly material with a wide range of applications.

above are only some upstream and downstream related products related to carbon dioxide. In fact, carbon dioxide is widely used in the chemical industry and can also be used to produce many other chemical products.
