Benzoic acid occurs naturally in many plants and serves as an intermediate in the biosynthesis of many secondary metabolites. Create a free website or blog at WordPress.com. . Method 1. When toluene is refluxed with alkaline KMnO4 solution (aqueous KMnO4 + Na2CO3), it is oxidised to benzoic acid. The acid is usually obtained in solution as its salt due to the alkaline nature of the reaction mixture. On neutralisation of the cooled reaction mixture with dil.HCl, benzoic acid gets precipitated as a white solid. 0000001016 00000 n starting material for the synthesis of benzoic acid benzaldehyde and many other. Isolation and Purification of Benzoic Acid After phenyl magnesium bromide is prepared, it is poured over powdered Dry-Ice (solid CO 2) to obtain the bromomagnesium salt of benzoic acid.
