What Are Commercial and Industrial Uses of Carbon Dioxide?

In MIG/MAG welding, CO2 serves as a so-called shield gas, which means that it protects the weld puddle from oxidation. In addition, in combination with argon, carbon dioxide is used to achieve an improved welding rate and to reduce the need for post-welding treatment.

Industrial Nitrogen Gas: Common Uses and Products

Nitrogen gas, or N₂, consists of diatomic molecules formed when two nitrogen atoms bond together. It is colorless, odorless, and chemically inert, making it ideal for industrial applications where chemical reactivity between materials must be avoided.

What Is Methyl Chloride Used For?

Methyl chloride is also employed as a methylating agent to attach CH3 groups to oxygen (as in methylcellulose) and nitrogen (as in quaternary ammonium salts) and as a solvent for the low-temperature preparation of butyl rubber.
