Aug 02, 2008 Sodium benzoate is a recognised antimicrobial which is very effective in synergy with potassium sorbate. Its optimum microbial activity occurs in the pH range 2.5- 4.0, indicating benzoic acid (pKa = 4.2) is the active form of this agent. It is used in beverages which are naturally acidic (Chichester and Tanner, 1968).

This reaction can be done with certain carboxylic acids themselves. For example, benzene can be made by heating soda lime with solid benzoic acid (benzenecarboxylic acid), C 6 H 5 COOH. You can think of this as first a reaction between the acid and the soda lime to make sodium benzoate, and then a decarboxylation as in the first example.
