Description

  

  Verfahren zur Herstellung eines     gerbenden    Stoffes.    Es wurde     gefunden,    dass durch     Einwü,-          kung    von Formaldehyd auf das     Sulfamid,    er  halten durch Einwirkung von     p-Toltiolsulfo-          chlorid    auf die     a-Aininonaphtalinmonosulfo-          säure    von     Cleve,    ein neuer wertvoller     Cerb-          stoff    erhalten wird. Dieser stellt ein in Was  ser leichtlösliches Pulver dar, welches Eiweiss  aus wässeriger Lösung sehr stark ausfällt.

      <I>Beispiel:</I>  110 Teile Formaldehyd     ä,    30     ",!o    werden  in eine schwach alkalische Lösung von 377  Teilen des     Sulfamides,    erhalten durch Ein  wirkung von     p-Toluolsulfochlorid    auf die       a-Aminonaphtalinmoiiosulfosätire        voll        Cleve,     eingetragen und das Ganze in     geschlossenem          Gefäss    auf 140-l50" während acht Stunden  erhitzt.

      Aus der so erhaltenen, zeit Mineralsäure       angesäuerten        Lösung    fällt Kochsalz     den    Gerb  stoff in Form einer     öligen"    bald fest werden  den Substanz     aus.  



  Process for the manufacture of a tanning material. It has been found that the action of formaldehyde on the sulfamide, obtained by the action of p-tololiol sulfochloride on the a-amino naphthalene monosulfonic acid from Cleve, gives a new valuable cerium. This is a powder that is easily soluble in water, which protein precipitates very strongly from aqueous solution.

      <I> Example: </I> 110 parts of formaldehyde ä, 30 ",! O are added to a weakly alkaline solution of 377 parts of the sulfamide, obtained by the action of p-toluenesulfochloride on the α-aminonaphthalene moiiosulfosätire full Cleve, and that Heat the whole thing in a closed vessel to 140-150 "for eight hours.

      From the solution obtained in this way, acidified by mineral acid, common salt precipitates the tannin in the form of an oily substance which will soon solidify.
