Description

  

  Verfahren zur Herstellung eines neuen als     Reservierungsmittel        verwendbaren     Kondensationsproduktes.    Es wurde gefunden, dass man ein neues  Kondensationsprodukt erhält, wenn man  auf das     ,Sulfonsäuregemisch,    das erhalten  wird durch     Behandeln    von 1     Mol        2-Oxynaph-          thalin    mit     sulfierend    wirkenden Mitteln,  1     Mol        Benzoin    einwirken lässt.  



  Das neue Produkt bildet ein helles -Pul  ver, das sich in Wasser leicht löst. Es ist  durch seine Affinität zur tierischen Faser  ausgezeichnet     und    soll zum Reservieren der  Wolle gegenüber Farbstoffen der verschie  densten Klassen oder als     Egalisierungsmittel     verwendet werden.  



  <I>Beispiel:</I>  14,5 Teile     2-Ogynaphthalin    werden unter  Rühren bei 60 bis<B>70'</B> in 70 Teile     100%ige     Schwefelsäure eingetragen. Hierauf erhitzt  man die Masse 3 bis 4 Stunden auf 100 bis  110  . Das     Sulfurierungsprodukt    wird er  kalten gelassen und mit 50 Teilen 100%iger  Schwefelsäure verdünnt. Dann trägt man  zwischen 20 bis 40' unter gutem Rühren 20    bis 25 Teile     Benzoin    ein. Nach einigem  Stehen verdünnt man die Kondensations  masse mit etwa 120 Teilen Eis, filtriert und  wäscht gegebenenfalls mit     Chlornatrium-          lösungetwas    nach.

   Der Rückstand wird dann  in Wasser gelöst, mit Natriumkarbonat oder       -hydroxyd    neutralisiert und, wenn nötig, von       Verunreinigungen        abfiltriert.        Das    neue Pro  dukt kann durch Versetzen dieser klaren Lö  sung mit     Chlornatrium    oder ähnlich wirken  den Salzen isoliert werden.  



  Die Aufarbeitung kann jedoch auch so  vor sich gehen, dass man die mit viel Wasser  verdünnte saure Kondensationsmasse mit Cal  ciumkarbonat oder     -hydroxyd    neutralisiert  und nach dem     Abfiltrieren    von     Calciumsulfat     in bekannter Weise mit Natriumkarbonat in  das     Natriumsalz    umsetzt.



  Process for the preparation of a new condensation product which can be used as a reservation agent. It has been found that a new condensation product is obtained if 1 mole of benzoin is allowed to act on the sulfonic acid mixture obtained by treating 1 mole of 2-oxynaphthalene with sulfating agents.



  The new product forms a light-colored powder that dissolves easily in water. It is characterized by its affinity for animal fibers and should be used to reserve the wool against dyes of the most diverse classes or as a leveling agent.



  <I> Example: </I> 14.5 parts of 2-ogynaphthalene are introduced into 70 parts of 100% sulfuric acid with stirring at 60 to 70 '. The mass is then heated to 100 to 110 for 3 to 4 hours. The sulfurization product is left cold and diluted with 50 parts of 100% sulfuric acid. 20 to 25 parts of benzoin are then introduced between 20 and 40 minutes with thorough stirring. After standing for a while, the condensation mass is diluted with about 120 parts of ice, filtered and, if necessary, rewashed with sodium chloride solution.

   The residue is then dissolved in water, neutralized with sodium carbonate or hydroxide and, if necessary, filtered off from impurities. The new product can be isolated by adding sodium chloride or similar salts to this clear solution.



  The work-up can, however, also proceed in such a way that the acidic condensation mass diluted with plenty of water is neutralized with calcium carbonate or hydroxide and, after the calcium sulfate has been filtered off, converted into the sodium salt in a known manner with sodium carbonate.
