  Verfahren zur Herstellung eines     neuen        Derivates    einer     Aminoclisulfonsäure.       Es     vulrde    befunden, dass man zu     einem     neuen Derivat einer     Aminodisulfonsäure    be  langt, wenn man 1.     11o1        2,6,8-Naphthylamin-          disulfonsäure    mit 1     Mol        ar-2-Chlormethyl-          tetrahyd@ronaphthalin    in     Gegenwart    eines  säurebindenden Mittels umsetzt.  



  Die Umsetzung wird zweckmässig bei 60  bis 75  vorgenommen. wobei man als     säure-          liiudendesMittel    vorteilhaft     Natriumcarbonai     verwendet.  



  Das     Dinatriumsalz    des neuen     Erzeub-          nis#ses    bildet ein gelblich gefärbtes Pulver,  das in Wasser mit schwach grüner Fluores  zenz klar löslich ist und     gute        Schaum-    und       Wascheigenschaften    besitzt. Es kann als       Textilhilfsstoff,    z.     B.*    als Waschmittel, An  wendung finden.  



  <I>Beispiel:</I>  In eine     Lösung    von 347 Gewichtsteilen  des     Dinatriumsalzes    der     2,6,8-Naphthyl-          amindisulfoii,c_äure    in 500     Volumteilen    Was  ser werden bei 70-75  unter Rühren 180     Ge-          wichtsteile        ar- -Ch.lormethyl-tetrahydronaph-          thalin    (1     11.1o1,

      innerhalb zwei     Stunden    ein-         betragen    und     bleichzeitig    so viel     Natrium-          carbonat        zusefiigt,    dass die Reaktionsmasse  stets schwach alkalisch reagiert. Nachdem  alles     ar-2-Chlormethy        1-tetrahydronaplithalin          einbetragen    ist und kein Alkali mehr ver  braucht wird, rührt man noch einige Stun  den bei der gleichen Temperatur weiter, stellt       hierauf    neutral und     da.mpfl-..die        entstandene     klare     Lösun'.    zur Trockne ein.

    



  Das auf diese Weise erhaltene     Aralkvlie-          rungsprodukt    bildet- ein gelblich     gefärbtes     Pulver, das in Wasser mit schwach grüner  Fluoreszenz klar löslich ist und gute Schaum  und Wascheigenschaften besitzt.



  Process for the preparation of a new derivative of an aminoclisulfonic acid. It has generally been found that a new derivative of an aminodisulfonic acid is obtained if 1,111 2,6,8-naphthylamino-disulfonic acid is reacted with 1 mol of ar-2-chloromethyl-tetrahydronaphthalene in the presence of an acid-binding agent.



  The reaction is conveniently carried out at 60 to 75. Sodium carbonate is advantageously used as the acid-releasing agent.



  The disodium salt of the new product forms a yellowish colored powder that is clearly soluble in water with a slightly green fluorescence and has good foam and washing properties. It can be used as a textile auxiliary, e.g. B. * as a detergent, to find application.



  <I> Example: </I> In a solution of 347 parts by weight of the disodium salt of 2,6,8-naphthylamine disulfoii, c_acid in 500 parts by volume of water, 180 parts by weight of ar- -Ch. lormethyl-tetrahydronaphthalene (1 11.101,

      be in within two hours and at the same time add enough sodium carbonate that the reaction mass always reacts weakly alkaline. After all the ar-2-chloromethyl 1-tetrahydronaplithalin has been entered and no more alkali has been used, the mixture is stirred for a few more hours at the same temperature, then neutralized and the resulting clear solution. to dry up.

    



  The aralkvlaze product obtained in this way forms a yellowish colored powder which is clearly soluble in water with a weak green fluorescence and which has good foam and washing properties.
