From sodium benzoate... preparation of Benzene
The conversion of sodium benzoate to benzene can be done a very famous organic reaction Kolbe's Decarboxylation reaction. The reaction involves reaction of a carboxylic acid with sodium hydroxide and calcium oxide ( known as soda-lime mixture ) and the mixture is heated which gives sodium carbonate and one less carbon alkane. Hence , it is a step-down reaction to decrease the number of carbons
Take the Sodium benzoate and put Sodium hydroxide and Calcium Oxide in it and heat the mixture. The reaction will yield Benzene and Sodium Carbonate as products.
Preparation of Benzene using Phenol
Distill Phenol with Zinc dust and add a bit of heat to give Zinc oxide along with Benzene
