Description

  

  Verfahren zur Herstellung eines neuen     Derivats    der     Phenylhydrazin-p-sulfonsäure.       Es wurde gefunden, dass man zu einem  -neuen     Derivat    der     Phenylhydrazin-p-,sulfon-          säure    gelangt, wenn     mann,    1     Mol        te.chn.        P.h:enyl-          hydrazin-p-sulfonsäure    mit 2     Mo:l        2-Chlor-          methyl-cymol    in Gegenwart eines säurebin  denden     Mittels        umsetzt.     



  Die Umsetzung     wird    zweckmässig bei 60  bis 75      vorgenommen,    wobei man als säure  bindendes Mittel vorteilhaft     Natriumcarbo-          nat    verwendet.  



  Das     Natriumsalz    des     neuen        Erzeugisses          bildet    ein farbloses, in     Wasser    nicht sehr  leicht lösliches Pulver von hoher Netzkraft  und     .gutem    Waschvermögen in neutralem  Bad.     Es    kann als-     Tegtilhilfsstoff,    z. B. als       Waschmittel,    verwendet     werden.     



       Beispiel:     Man     neutralisiert    26,2 Gewichtsteile       techn.        phenylhydrazin    - p -     sulfonsaures    Na  trium     (68%ig    auf     Phenylhydrazinsulfon-          säure    berechnet)     mieseiner    10 %     igen        Natrium-          carbonatlösung    und     lässt        unter    Rühren bei  65-70      inn'erhal'        =#on    3     Stunden    36,

  4 Ge-         wichtsteile        2-Chlo@rmethyl-cymol    gleichzeitig  mit etwas mehr als der äquivalenten Menge       einer    20     %igen        Natriumcarbonatlösung    zu  fliessen.     Hierauf    rührt man die     Mischung     noch während     etwa    10     Stunden    bei derselben  Temperatur, wonach eine Probe der     Re-          a.ktionsflüssigkeit    beim     Verdünnen    mit Was  ser klar löslich ist. Die Lösung wird darauf       neutralisiert    und zur Trockne eingedampft.  



  Die Ausbeute an Trockenprodukt beträgt  68,2     Gewichtsteile.     



  Das so     erhaltene        N-di-(cymylmethyl)-          phenylhydrazin-p-sulfo.nsaure    Natrium     bil-          Jet        ein    farbloses,     in    Wasser nicht sehr leicht  lösliches Pulver von hoher Netzkraft und  gutem     Waschvermögen        in,        neutralem    Bad.



  Process for the preparation of a new derivative of phenylhydrazine-p-sulfonic acid. It has been found that a -new derivative of phenylhydrazine-p-, sulfonic acid is obtained if one mole of te.chn. P.h: enylhydrazine-p-sulfonic acid with 2 Mo: l 2-chloromethyl-cymene in the presence of an acid-binding agent.



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



  The sodium salt of the new product forms a colorless powder, which is not very easily soluble in water, of high wetting power and good washing power in a neutral bath. It can be used as a Tegtilhilfsstoff, z. B. can be used as a detergent.



       Example: 26.2 parts by weight of techn. phenylhydrazine - p - sulphonic acid sodium (68% based on phenylhydrazinesulphonic acid) poor 10% sodium carbonate solution and leaves with stirring at 65-70 within 3 hours 36,

  4 parts by weight of 2-chloromethyl-cymene to flow simultaneously with a little more than the equivalent amount of a 20% sodium carbonate solution. The mixture is then stirred for about 10 hours at the same temperature, after which a sample of the reaction liquid is clearly soluble when diluted with water. The solution is then neutralized and evaporated to dryness.



  The yield of dry product is 68.2 parts by weight.



  The N-di- (cymylmethyl) -phenylhydrazine-p-sulfonic acid sodium obtained in this way forms a colorless powder, not very easily soluble in water, of high wetting power and good washing power in a neutral bath.
