Versuchsvorschrift

The operation was carried out in the same manner as in Example 1 except that the reaction product of chlorosulfonic acid and chlorobenzene was dropwise added to 788 g of 60% sulfuric acid. After the liquid phase separation, about 1100 g of sulfuric acid having a concentration of 73% was obtained from the lower layer. From the upper layer, 286 g of chlorobenzene sulfochloride having a purity of 92% was obtained. The yield based on the feed chlorobenzene was 83%.
