Description

  

      Verfahren    zur Herstellung eines neuen Derivates einer     Aminosulfonsäure.            Es    wurde     gefunden,        dass    man zu einem  neuen Derivat einer     Aminosulfonsäure    ge  langt, wenn man 1     Mol        ss-Aminoäthansulfon-          säure    mit 1     Mol        ar-2-Chlormethyl-tetrahydro-          naphthalin    in     Gegenwart    eines     säurebinden-          .den        Miltels    umsetzt.  



  Die Umsetzung wird zweckmässig bei 60  bis 75  vorgenommen, wobei :man als säure  bindendes     Mittel        vorteilhaft        Natriumcarbonat     verwendet.  



       Das        Natriumsalz    des erhaltenen Erzeug  nisses bildet ein hygroskopisches, in     Wasser     nicht sehr leicht     lösliches    Pulver, das gute       kapillaraktive        EEigenschaftm,        insbesondere     ein     gutes    Netzvermögen,     besitzt.    Es kann als       Textilhilfsstoff,    z. B. als     -Netzmittel,    verwen  det werden.  



       Beispiel:     18     Gewichtsteile        ss-@aminoäthänsulf        onsaures     Natrium erhitzt man zusammen mit 100 Ge  wichtsteilen Wasser, 800     Gewichtsteilen    Me  thylalkohol und 24 Gewichtsteilen     ar-2-          Chlo@rmethyl-tetrahydronaphthaIin    am Rück  flusskühler zum     Sieden,    wobei man die Re-         Aktionslösung    durch Zusatz von Natronlauge       stets    schwach     alkalisch    hält.  



  Nach einigen Stunden ist die     Umsetzung          beendet.    Man     neutralisiert        das        Reaktions-          gemisch    und dampft     dieses    im     Vakuum.    zur  Trockne     ein.    Das     getrocknete        S@alzgemisöh     kann durch     Extraktion    mit     absolutem    Al  kohol     gereinigt    werden.  



       Das    erhaltene     ss-mon-otetrahydronaphthyl-          methylaminoäthansuHons-aure        Natrium    bil  det ein-     hygroskopisches,    in     Wasser        nicht    sehr  leicht     lö@sliehes        Pulver,    das gute kapillar  aktive     Eigenschaften,        insbesondere    ein gutes       Netzvennöger@,    besitzt.



      Process for the preparation of a new derivative of an aminosulfonic acid. It has been found that a new derivative of an aminosulfonic acid is obtained if 1 mol of β-aminoethanesulfonic acid is reacted with 1 mol of ar-2-chloromethyl-tetrahydronaphthalene in the presence of an acid-binding agent.



  The reaction is expediently carried out at 60 to 75, in which case sodium carbonate is 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 and which has good capillary-active properties, in particular good wetting properties. It can be used as a textile auxiliary, e.g. B. as a wetting agent, are used.



       Example: 18 parts by weight of sodium ss- @ aminoäthensulfonsaures are heated together with 100 parts by weight of water, 800 parts by weight of methyl alcohol and 24 parts by weight of ar-2-Chlo @ rmethyl-tetrahydronaphthaIin on the reflux condenser to boiling, the Re- action solution by adding Keeps sodium hydroxide solution always slightly alkaline.



  The reaction has ended after a few hours. The reaction mixture is neutralized and evaporated in vacuo. to dry up. The dried S @ alzgemisöh can be cleaned by extraction with absolute alcohol.



       The obtained ss-mon-otetrahydronaphthylmethylaminoethansuHonic acid sodium forms a hygroscopic powder which is not very easily soluble in water and which has good capillary active properties, in particular good network properties.
