Description

  

      Verfahren    zur Herstellung eines neuen Derivates einer     Aminosulfonsäure.       Es wurde befunden, dass man zu einem  neuen Derivat einer     Aminosulfonsäure    ge  langt, wenn man 1     Mol        ss-        Amino-ätha,nsulfon-          säure    mit     2Mol        2-Chlormethyl-cymol    in       Gegenwarf:    eines     säurebindenden    Mittels um  setzt.  



  Die Umsetzung wird zweckmässig bei 60  bis 75  vorgenommen, wobei man als säure  binden.desMitte1 vorteilhaft     Natriumcarbonat     verwendet.  



  Das     Natriumsalz    des erhaltenen Erzeug  nisses bildet. ein hygroskopisches, in     'Wasser     nicht sehr leicht lösliches Pulver, das ein her  vorragendes Netzvermögen besitzt und als  Netzmittel verwendet werden kann.  



  <I>Beispiel:</I>  18     Gewichtsteile        ss-aminoäthansulfosaures     Natrium werden zusammen mit 100     Ge-          wi.cht:steilen    Wasser, 300 Gewichtsteilen       '_1fe        thylalkohol    und 48 Gewichtsteilen     2-Chlor-          rncthy        l-cymol    am     Rückflusskühler        gekocht,       wobei man die     Reaktionsmischung    durch Zu  satz von     Natronlaub    stets schwach alkalisch  hält.  



  Nach einigen Stunden ist der Umsatz     he-          endet,    worauf man die     Reaktionslösung    mit  einer     Mineralsäure    neutralisiert und im Va  kuum zur Trockne eindampft. Durch Extrak  tion des trockenen Rückstandes mit absolutem  Alkohol kann das Produkt salzfrei erhalten  werden.  



  Das erhaltene     ss-dicymylmethyl-amino-          äthansulfosaure    Natrium bildet ein hygrosko  pisches, in Wasser nicht sehr .leicht lösliches  Pulver,     d.ae    ein     hervorragendes        Netzvermögen     besitzt.



      Process for the preparation of a new derivative of an aminosulfonic acid. It was found that a new derivative of an aminosulfonic acid is obtained if 1 mol of β-amino-etha, nsulfonic acid is reacted with 2-mol of 2-chloromethyl-cymene in the presence of an acid-binding agent.



  The reaction is expediently carried out at 60 to 75, with sodium carbonate being advantageously used as the acid binding agent.



  The sodium salt of the product obtained forms. a hygroscopic powder which is not very easily soluble in water, has excellent wetting properties and can be used as a wetting agent.



  <I> Example: </I> 18 parts by weight of β-aminoethanesulfonic acid sodium are boiled together with 100 parts by weight of steep water, 300 parts by weight of methyl alcohol and 48 parts by weight of 2-chloroethanesulfonic acid on a reflux condenser, whereby one the reaction mixture is always kept slightly alkaline by adding soda leaves.



  After a few hours the conversion has ended, whereupon the reaction solution is neutralized with a mineral acid and evaporated to dryness in a vacuum. The product can be obtained salt-free by extracting the dry residue with absolute alcohol.



  The sodium ss-dicymylmethylamino ethane sulfonic acid obtained forms a hygroscopic powder which is not very easily soluble in water and which has excellent wetting properties.
