Description

  

  Verfahren zur Herstellung eines neuen     Pyridiniumehlorids.       Es wurde gefunden, dass man zu einem  neuen     Pyridiniumchlorid    gelangt, wenn man  das ätherartige     Kondensationsprodukt    aus       ss-Naphthol    und     Dipenten    durch Behandeln  mit     a,a.'-Dichlordimethyläther    in ein Chlor  methylderivat überführt und anschliessend       Pyridin    auf das so erhaltene     Chlormethyl-          derivat    einwirken lässt.  



  Die Umsetzung mit dem     a,ä        -Dichlordime-          thy        läther    wird zweckmässig in der Wärme  und in Gegenwart eines Kondensationsmit  tels, wie Zinkchlorid, vorgenommen.  



  Das neue     Pyridiniumchlorid    ist ein Pul  ver, das von Wasser leicht zu einer schäu  menden Lösung aufgenommen wird und das       Sulfogruppen    enthaltende Farbstoffe aus  ihren wässerigen Lösungen ausfällt. Es     kann     als     Tegtilhilfsstoff,    z. B. zum Schiebefest  machen von Geweben, verwendet werden.

      <I>Beispiel:</I>  Man erwärmt 5 Gewichtsteile des äther  artigen Kondensationsproduktes aus ss-Naph-         thol    und     Dipenten        (Sdp.    180-190  bei einem  Druck von 0,5 mm Quecksilbersäule) mit  4,1 Gewichtsteilen     a,a'-Dichlordimethyläther     und 0,05 Gewichtsteilen pulverisiertem,  wasserfreiem Zinkchlorid unter Rühren wäh  rend einer Stunde in einem Bad von 60-65 .

    Die flüchtigen Anteile werden darauf unter  vermindertem Druck aus einem Bad von 60  bis 80      abdestilliert.    Man fügt 13     Volumteile          Pyridin    zu. dem erhaltenen Rückstand, er  wärmt während etwa 15 Minuten in einem  siedenden Wasserbad, lässt bei Raumtempera  tur einige Stunden stehen, trennt von wenig  ungelöstem Harz ab und versetzt mit     Petrol-          äther.    Das     ausgefällte,    vom anhaftenden Lö  sungsmittel befreite Reaktionsprodukt stellt  ein in Wasser leicht lösliches Pulver dar. Die  wässerige Lösung schäumt und fällt     Sulfo-          gruppen    enthaltende Farbstoffe.

   Das neue  Produkt kann zum     Schiebefestmachen    von  Geweben verwendet werden.  



  Das als Ausgangsstoff verwendete äther  artige Kondensationsprodukt aus     ss-Naphthol         und     Dipenten    kann in gleicher Weise bereitet  werden wie der in der französischen Patent  schrift Nr. 539494 beschriebene Äther aus       Carven    und     ss-Naphthol.  



  Process for the preparation of a new pyridinium chloride. It has been found that a new pyridinium chloride is obtained if the ethereal condensation product of β-naphthol and dipentene is converted into a chloromethyl derivative by treatment with α, α'-dichlorodimethyl ether and then pyridine is allowed to act on the chloromethyl derivative obtained in this way .



  The reaction with the α, α-dichlorodimethy ether is expediently carried out in the heat and in the presence of a condensation agent such as zinc chloride.



  The new pyridinium chloride is a powder that is easily absorbed by water to form a foaming solution and the dyes containing sulfo groups precipitate out of their aqueous solutions. It can be used as a Tegtilhilfsstoff, z. B. to make fabrics slip-proof.

      <I> Example: </I> 5 parts by weight of the ethereal condensation product of ss-naphthol and dipentene (boiling point 180-190 at a pressure of 0.5 mm of mercury) are heated with 4.1 parts by weight of a, a ' -Dichlorodimethyl ether and 0.05 parts by weight of powdered, anhydrous zinc chloride with stirring during one hour in a bath of 60-65.

    The volatile components are then distilled off from a bath of 60 to 80 under reduced pressure. 13 parts by volume of pyridine are added. the residue obtained, it is warmed in a boiling water bath for about 15 minutes, left to stand for a few hours at room temperature, separated from a little undissolved resin and treated with petroleum ether. The precipitated reaction product, freed from adhering solvent, is easily found in water soluble powder. The aqueous solution foams and falls dyes containing sulfo groups.

   The new product can be used for securing fabrics to slide.



  The ether-like condensation product of ss-naphthol and dipentene used as the starting material can be prepared in the same way as the ether from carving and ss-naphthol described in French patent no. 539494.
