Description

  

  Verfahren zur Herstellung eines neuen als     Reservierungsmittel     verwendbaren Kondensationsproduktes.    Es wurde gefunden, dass man ein neues  Kondensationsprodukt erhält, wenn man 1     Mol          Benzoin    und 1     Mol    2 -     Oxynaphthalin    -     3,6-          disulfosäure    kondensiert.  



  Das neue Produkt bildet ein helles Pul  ver, das sich in Wasser leicht löst. Es ist  durch seine Affinität zur tierischen Faser aus  gezeichnet und soll zum Reservieren der Wolle  gegenüber Farbstoffen der verschiedensten  Klassen oder als     Egalisierungsmittel    verwen  det werden,         Beispiel:       40 Teile     technisches    2 -     naphthol-    3,6 -     di-          sulfosaures    Natrium werden in 250 Teilen  konzentrierter Schwefelsäure gelöst. Hierauf  trägt man zwischen     20--400    unter gutem  Rühren 20-25 Teile     Benzoin    ein.

   Nach  einigem Stehen verdünnt man mit etwa 250  Teilen Eis, filtriert und wäscht gegebenen  falls mit     Chlornatriumlösung    etwas nach. Der    Rückstand wird dann in Wasser gelöst, mit       Natriumcarbonat    oder     -hydroxyd    neutralisiert  und, wenn nötig, von Verunreinigungen ab  filtriert. Das neue Produkt kann durch Ver  setzen dieser klaren Lösung mit Chlornatrium  oder andern ähnlich wirkenden Salzen isoliert  werden. Hierauf wird getrocknet und pul  verisiert.  



  Die Aufarbeitung kann jedoch auch so  vor sich gehen, dass man die mit viel Wasser  verdünnte saure Kondensationsmasse mit     Cal-          ciumearbonat    oder     -hydroxyd    neutralisiert  und nach dem     Abfiltrieren    von     Caleiumsulfat     mit     Natriumcarbonat    in das     Natriumshlz     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 when 1 mol of benzoin and 1 mol of 2-oxynaphthalene-3,6-disulfonic acid are condensed.



  The new product forms a light-colored powder that easily dissolves in water. It is characterized by its affinity for animal fibers and should be used to reserve the wool against dyes of various classes or as a leveling agent, example: 40 parts of technical 2 - naphthol - 3,6 - disulphonic acid are more concentrated in 250 parts Dissolved sulfuric acid. 20-25 parts of benzoin are then added with good stirring between 20-400 parts.

   After standing for a while, it is diluted with about 250 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 to remove impurities. The new product can be isolated by adding this clear solution with sodium chloride or other similar salts. It is then dried and pulverized.



  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 carbonate with sodium carbonate.
