Versuchsvorschrift

The test described in Example 1 was repeated using 300 g of p-fluorotoluene, 660 g of acetic acid, 132 g of water, 6 g of cobalt acetate tetrahydrate, 5 g of sodium bromide and 5 g of sodium acetate. In a reaction time of 240 minutes, after conventional work-up, 330.5 g of p-fluorobenzoic acid (86.6% of the theory) was obtained, with a purity of 99.9%.
