HCID 7470P-Toluic Acid

Procedure

In the like manner as Example 1, 23.6 g of p-methylbenzaldehyde as an aldehyde and 3 g of phosphoric acid were used. The oxidation was done by using 23 g of calcium hypochlorite at temperatures of -5° to -3° C., which was followed by refining to obtain p-methylbenzoic acid.

Workup
