Description

  

  Verfahren zur Darstellung eines neuen Kondensationsproduktes.    Das vorliegende Patent betrifft ein Ver  fahren zur Darstellung eines neuen Konden  sationsproduktes, welches dadurch gekenn  zeichnet ist, dass man 1     Mol.        Diäthanolamin     mit     '/2        Mol.    a,     r-Glyzerindichlorbydrin    kon  densiert, das so erhaltene Polyamin durch Be  handeln mit     Thionylchlorid    in die entspre  chende     Ohloralkylverbindung    überführt und  diese mit     Pyridin    umsetzt.  



  Das so gewonnene Kondensationsprodukt  stellt in trockenem Zustande ein hellbraunes  Harz dar, welches in Wasser ohne weiteres  leicht löslich ist und zur Erhöhung der Echt  heitseigenschaften von mit Substantiven Farb  stoffen erhaltenen Färbungen verwendet wer  den kann.  



  <I>Beispiel:</I>  47 Teile     Diäthanolamin    werden mit 32,5  Teilen     Glyzerindichlorhydrin    bei 180-195   C  kondensiert und auf 320 C abkühlen gelas  sen. Bei dieser Temperatur wird das Konden  sationsprodukt mit 150 Teilen     Thionylchlorid     versetzt, wobei die Temperatur rasch auf  70-73   C steigt. Man rührt nun die weiche  hellgelbe Paste noch ca. 3 Stunden lang bei  <B>70'</B> C und bläst das überschüssige Thionyl-         chlorid,    Salzsäure und     S02    mit einem Strom  warmer Luft ab. Bei 70   C versetzt man  nun das     Halogenierungsprodukt    mit 200 Tei  len     Pyridin    und erwärmt 4 Stunden auf 116  bis<B>1180</B> C.

   Man erhält beim Abkühlen ein  hellbraunes Harz, das ohne weiteres als     Fäl-          lungsmittel    verwendet werden kann.



  Process for the preparation of a new condensation product. The present patent relates to a process for the preparation of a new condensation product, which is characterized in that 1 mol. Diethanolamine is condensed with 1/2 mol. A, r-glycerol dichlorobydrin, the polyamine obtained in this way by treatment with thionyl chloride the corre sponding Ohloralkylverbindungen transferred and this reacts with pyridine.



  The condensation product obtained in this way is a light brown resin in the dry state, which is readily soluble in water and can be used to increase the authenticity properties of dyeings obtained with substantive dyes.



  <I> Example: </I> 47 parts of diethanolamine are condensed with 32.5 parts of glycerol dichlorohydrin at 180-195 C and allowed to cool to 320 C. At this temperature the condensation product is mixed with 150 parts of thionyl chloride, the temperature rising rapidly to 70-73 C. The soft, pale yellow paste is then stirred for about 3 hours at 70 ° C and the excess thionyl chloride, hydrochloric acid and SO2 are blown off with a stream of warm air. At 70 C, the halogenation product is then mixed with 200 parts of pyridine and heated for 4 hours to 116 to 1180 C.

   On cooling, a light brown resin is obtained which can easily be used as a precipitant.
