 weiter nach Beispiel 2 und 3. Die so erhaltene Säure enthält zwei schwefelhaltige, saure Gruppen und ihr Natriumsalz zwei Atome Natrium. 



   B e i s p i e l 5 : 50 Teile Diaminodioxyarsenobenzchlorhydrat werden in 200 Teilen Glykol gelöst und zu dieser Lösung eine solche von   31@   Teilen Formaldhydsulfoxylat in 50 Teilen Wasser zugegeben. Nach   fünf Minuten langem Rühren   wird Sodalösung zugegeben, bis die Lösung neutral reagiert. Es entsteht so eine gebrauchsfertige, neutral reagierende Lösung des   Diaminodioxy

 continue according to Examples 2 and 3. The acid thus obtained contains two sulfur-containing, acidic groups and its sodium salt contains two sodium atoms.



   Example 5: 50 parts of diaminodioxyarsenobenz chlorohydrate are dissolved in 200 parts of glycol and one of 31 parts of formaldehyde sulfoxylate in 50 parts of water is added to this solution. After stirring for five minutes, soda solution is added until the solution reacts neutrally. The result is a ready-to-use, neutrally reacting solution of the diaminodioxy
