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.

Carbon dioxide is odorless at normally encountered concentrations. Sodium compounds Revolvy Brain revolvybrain. Azo coupling of 3-hydroxynaphthoic acid gives many dyes as well.

Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers and seawater. The final product is an aromatic hydroxy acid which is also known as salicylic acid the precursor to aspirin. A reagent that delivers the formyl reactioon is called a formylating agent. First used inthe term served to distance these medications from steroids.
