Procedure

64.1 g (0.5 mol) of naphthalene and 640.7 g (5.5 mol) of chlorosulfonic acid are reacted as in Example 26, but without addition of sulfamic acid. 139.4 g of naphthalene-1,5-disulfonyl chloride having a water content of 25.8% and a chloride content of 72.5%, corresponding to 101.1 g (62.2%), are obtained.
