4 kg of an aquoeus sulfuric acid solution of quinoline (composition: 6% by weight of quinoline, 9.1% by weight of sulfuric acid, remainder water as in Example 29) are ozonized with 2500 l (STP) of O2/O3 with 100 g of O3/Nm3 in a batchwise manner until the quinoline content had dropped to 0.9 g/l. Ozonization is then continued with the same amount of gas and ozone concentration, and the quinoline concentration is maintained between 0.7 g/l and 0.9 g./l as a result of the metered addition of aqueous sulfuric acid quinoline solution. The offgas comprised 63 g of 3/Nm3 at the start of the continuous procedure, and 59 g of O3/Nm3 at the end of the experiment. The ozone consumption was measured and was 230% of theory, calculated on the basis of quinoline, which suggests massive secondary reactions and further reactions of the cleavage products. Finally, PDC began to precipitate out of the solution, which blocked the absorption column.
