Introduction
The Kolbe–Schmitt reaction/Kolbe process is a carboxylation chemical reaction that proceeds by heating sodium phenolate (the sodium salt of phenol) with carbon dioxide under pressure (100 atm, 125 °C), then treating the product with sulfuric acid.

What you learn in Theory:
The Kolbe–Schmitt reaction/Kolbe process is a carboxylation chemical reaction that proceeds by heating sodium phenolate (the sodium salt of phenol) with carbon dioxide under pressure (100 atm, 125 °C), then treating the product with sulfuric acid.
What you learn in Practice:
The Kolbe–Schmitt reaction proceeds via the nucleophile addition of a phenolate to carbon dioxide to give the salicylate. The final step is reaction of the salicylate with acid to form the desired salicylic acid.
