Description

  

  Verfahren zur Darstellung eines     Aminoarylsulfonsäurederivates.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Darstellung eines     Amino-          arylsulfonsäurederivates,    dadurch gekennzeich  net, dass man     4-Amino-4'-chlor-5'-methyl-          1,1'-diphenyläther-2-sulfonsäure    mit     Chlor-          methyl-dodecyläther    umsetzt.  



  Die neue     VerbindunLy    der Formel  
EMI0001.0009     
    bildet als     Kaliumsalz    ein helles, in Wasser       lösliohes    Pulver und eignet sich als Motten  schutzmittel.  



  <I>Beispiel:</I>  10 Teile     4-Amino-4'-chlor-5'-methyl-1,1'-          diphenyläther-2-sulfonsäure    werden in 100       Vol.-Teilen    Benzol suspendiert, 8 Teile     Chlor-          methyl-dodecyläther    dazu gegeben und zum  Sieden erhitzt. Die entstehende Säure wird  allmählich mit 5 Teilen     galiumcarbonat    ab-    gestumpft. Nachdem in einer Probe kein  freies Amin mehr nachgewiesen werden kann,  wird das ausgeschiedene Produkt isoliert  und im Vakuum getrocknet. Es bildet ein  helles, in Wasser lösliches Pulver.



  Process for the preparation of an aminoarylsulfonic acid derivative. The present patent relates to a process for the preparation of an aminoaryl sulfonic acid derivative, characterized in that 4-amino-4'-chloro-5'-methyl-1,1'-diphenyl ether-2-sulfonic acid is mixed with chloromethyl dodecyl ether implements.



  The new compound of the formula
EMI0001.0009
    As the potassium salt, it forms a light-colored powder that is soluble in water and is suitable as a moth repellent.



  <I> Example: </I> 10 parts of 4-amino-4'-chloro-5'-methyl-1,1'-diphenylether-2-sulfonic acid are suspended in 100 parts by volume of benzene, 8 parts of chloromethyl -dodecyl ether added and heated to the boil. The acid formed is gradually blunted with 5 parts of galium carbonate. After no more free amine can be detected in a sample, the precipitated product is isolated and dried in vacuo. It forms a light-colored powder that is soluble in water.
