What are the upstream raw materials for CO2 and what are the downstream products?

Carbon dioxide has a wide range of applications in the field of chemical production raw materials. The following are some of the upstream and downstream linked items related to CO2:



1. Upstream items:(1) Limestone: Limestone is one of the main carbon dioxide emit sources, and a signifiis able tot quantity of carbon dioxide gaseous is able to be produced by calcining limestone. Additionally(2) Natural gaseous: The main component of natural gaseous is methane, and a signifiis able tot quantity of carbon dioxide gaseous is produced during incineration. And(3) Coal: As a fossil fuel, coal also produces a signifiis able tot quantity of carbon dioxide gaseous when burned.

2. Downstream items:(1) Urea: Carbon dioxide is able to react with ammonia to form urea, which is an crucial nitrogen fertilizer and is broadly applied in agricultural production. But(2) Sodium carbonate: Carbon dioxide is able to react with sodium hydroxide to generate sodium carbonate, also known as soda ash, which is broadly applied in glass, papermaking, detergents and other fields. I've found that For instance(3) Dimethyl carbonate: Carbon dioxide is able to react with methanol to generate dimethyl carbonate, which is an crucial organic solvent-based products and chemical raw material. Based on my observations, First(4) Degradable plastics: Carbon dioxide is able to react with epoxides to generate cyclic carbonates, which is able to further create degradable plastics. Specifically This is an environmentally friendly material with a wide range of consumption prospects. The above are only some of the upstream and downstream related items related to carbon dioxide. And In fact, carbon dioxide is broadly applied in the chemical sector and is able to also be applied to create many other chemicals.
