Useful:

• Chemical Classes: Other Classes -> Organic Acids
• Canonical SMILES: C(=O)(O)O
• Physical properties: Carbonic acid has the formulaH2CO3 (equivalently OC(OH)2). It is also a name sometimes given to solutions of CO2 in water
• Uses: Carbonic acid is used in the manufacture of soft drinks, inexpensive and artificially carbonated sparkling wines, and other bubbly drinks. Carbonic acid (H2CO3) is produced by dissolving carbon dioxide in water. When formed under pressure, it is the gas used in carbonated drinks. In nature, it dissolves the limestone in caves, resulting in the formation of stalactites and stalagmites. It is corrosive as are other acids, although it is considered a rather weak acid.

Technology Process of Carbonic Acid

There total 379 articles about Carbonic Acid which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:
