実験手順

The experiment described in Example 8 was performed with the use of 200 g of p-xylene, 1000 g of acetic acid, 10 g of cobalt acetate tetrahydrate (corresponding to 2.37 g of cobalt) and 2.75 g of potassium bromide (corresponding to 1.86 g of bromine). After a reaction time of 252 minutes and an oxygen absorption of 147.2 liters, 294.5 g of terephthalic acid was obtained. After the addition of 4.7 g of oxalic acid, 7.4 g of cobalt oxalate dihydrate was isolated from the mother liquor.
