Approximately 139,000 tons of benzoic mountain is synthesized synthetically annually for usage in a huge variety the industries. Benzoic acid have the right to be prepared by oxidation process of benzyl chloride in the presence of alkaline potassium permanganate:
C6H5CH2Cl + 2 KOH + 2
Benzoic acid is mostly dissipated in the manufacturing of phenol. Benzoic acid and its salt are greatly used as food preservatives.
