Application of benzoic acid
Benzoic acid is widely found in nature in the form of free acid, ester or its derivatives. It is mainly used in the preparation of sodium benzoate as a preservative, and in the synthesis of drugs and dyes; it is also used in the preparation of plasticizers, mordants, fungicides and spices. It can be obtained by direct oxidation of toluene in the presence of manganese dioxide; or by decarboxylation of phthalic anhydride with water vapor.
