KOLBE-SCHMITT REACTION PDF

The Kolbe-Schmitt reaction is an organic reaction used to convert a phenol to a hydroxy benzoic acid using carbon dioxide gas, a base, and acid work-up. The Kolbe-Schmitt reaction has been a standard procedure for the preparation of the Kolbe-Schmitt reaction in the form of a general survey. Special emphasis.
