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 mechanism begins with deprotonation of the phenol by the base to form a phenoxide.

 kolbe schmitt reaction is  a carboxylation chemical reaction that proceeds by heating sodium phenolate  with carbon dioxide under pressure (100 atm, 125 °C), then treating the product with sulfuric acid.

Hello guravaiah,
a method of obtaining hydrocarbons by the electrolysis of solutions of the salts of carboxylic acids .The Kolbe reaction is used in industry, for example, to obtain sebacic acid, which is used in the production of polyamides and aromatic substances. The reaction was proposed by the German chemist A. W. H. Kolbe in 1849.
           RCOO- + R’OOC(CH2)n COO-→R(CH2)n COOR’ 2ROOC(CH2)n COO-→ROOC(CH2)n COOR

Hello Guravaiah
                        Definition of Kolbe reaction. 1 : the synthesis of a hydrocarbon (as ethane) by the electrolysis of a salt (as sodium acetate) 2 : the synthesis of salicylic acid by heating a mixture of sodium phenoxide and carbon dioxide under pressure at 180° to 200° C.
