Description

  

  Verfahren     zur        Herstellung    von     Schwefelfarbstoffen    der     Phthalocyaninreihe       Gegenstand des Hauptpatentes ist ein Verfahren  zur Herstellung von     Schwefelfarbstoffen    der     Phthalo-          cyaninreihe,    dadurch gekennzeichnet,

       dass    man auf       metallfreie        Polyanünophthalocyanine    oder deren       Metallkomplexsalze        Chlorsulfonsäure    und mindestens  5     Mol    Chlorschwefel pro     Mol    der     Polyaminophthalo-          cyaninverbindung    bei einer Temperatur von 70 bis  150  einwirken lässt. Die so erhaltenen Farbstoffe be  sitzen     grünstichig    bis blaustichig     olivgraue    Farbnuan  cen und sie     liefern    Färbungen von ausgezeichneter  Lichtechtheit.  



  Es wurde nunmehr gefunden, dass man dieses  Verfahren     vorteilhaft    derart ausführen kann, dass man  auf ein durch Einwirkung von     Hydroxylamin    oder       Hydroxylamin    liefernden Substanzen in     Chlorsulfon-          säure    auf     metallfreie        Phthalocyanine    oder deren       Metallkomplexsalze    in Gegenwart von Verbindungen  von Elementen der 5. oder 6. Gruppe des peri  odischen 'Systems (wie z.

   B.     Ammoniummolybdat    oder       Vanadiumpentoxyd)    erhaltenes,     metallfreie        Poly-          aminophthalocyamine    oder     Metallkomplexsalze    der  selben enthaltendes Reaktionsgemisch     mindestens    5       Mol    Chlorschwefel pro     Mol    der     Phthalocyaninverbin-          dung    bei einer Temperatur von 70 bis 150  C ein  wirken lässt.  



  <I>Beispiel 1</I>  23 Teile     Kupferphthalocyanin,    15,6     Teile          95o/oiges        Hydroxylaminsulfat    und 0,11 Teile     Am-          moniummolybdat    werden in 345 Teilen     Chlorsulfon-          säure    2 Stunden bei 115      gerührt.    Dann werden in  nerhalb 10-15 Minuten 40,5 Teile Chlorschwefel  eingetropft. Dieses Gemisch wird 1 Stunde bei 115   gerührt und nach Abkühlen auf 30  in die     5-6-fache     Menge Wasser gegossen.

   Der in bekannter Weise  isolierte Farbstoff färbt die     Textilfaser    aus stumpf  stahlblauer     Schwefelnatriumlösung    in     grünstichig    oliv-    grauen Tönen von guter Wasch- und sehr guter Licht  echtheit.  



  Rührt man mit     Hydroxylamin    nicht 2 Stunden  bei 115  sondern 3 Stunden bei     105     unter sonst  unveränderten Versuchsbedingungen, so erhält man  einen -etwas     blaustichigeren    Farbstoff von gleichen  Echtheitseigenschaften.  



  Rührt man     mit    Chlorschwefel nicht 1     sondern     3 Stunden und arbeitet sonst unter den gleichen Be  dingungen, so erhält man einen Farbstoff von prak  tisch den gleichen Eigenschaften.  



  <I>Beispiel 2</I>  23 Teile     Kupferphthalocyanin,    15,6     Teile     95     1/oiges        Hydroxylaminsulfat    und 0,11 Teile     Am-          moniummolybdat    werden in 345 Teilen     Chlorsulfon-          säure    24 Stunden bei 85  gerührt.

   Dann werden in  nerhalb 10-15 Minuten 40,5     Teile    Chlorschwefel       eingetropft.    Dieses Gemisch wird 2 Stunden bei 85   gerührt und nach Abkühlen auf     etwa    30  in die       5-6fache    Menge Wasser     eingetropft.    Der in     üblicher     Weise isolierte     Farbstoff    färbt die     Textilfaser    aus  schmutzig blaugrüner     Schwefelnatriumlösung    in blau  stichig     olivgrauen    Tönen von guter Wasch- und sehr  guter Lichtechtheit.  



  Ersetzt man die     in    diesem Beispiel     verwendeten     15;6 Teile 95     o/o@iges        Hydroxylaminsulfat    durch 25,9  Teile 91     o/oiges    saures     Hydroxylaminsulfat          (NH20H        #        H2SO4),     so     erhält    man     ein    Produkt mit praktisch gleichen     fär-          berischen    Eigenschaften.



  Process for the production of sulfur dyes of the phthalocyanine series The subject of the main patent is a process for the production of sulfur dyes of the phthalocyanine series, characterized in that

       that chlorosulfonic acid and at least 5 moles of chlorosulfur per mole of the polyaminophthalocyanine compound are allowed to act at a temperature of 70 to 150 on metal-free polyamino phthalocyanines or their metal complex salts. The dyes obtained in this way have greenish to bluish olive-gray shades and they give dyeings of excellent lightfastness.



  It has now been found that this process can advantageously be carried out in such a way that one reacts to a substance in chlorosulfonic acid which is provided by the action of hydroxylamine or hydroxylamine on metal-free phthalocyanines or their metal complex salts in the presence of compounds of elements of the 5th or 6th group of the periodic 'system (such as

   B. ammonium molybdate or vanadium pentoxide) obtained, metal-free polyaminophthalocyamines or metal complex salts of the same containing reaction mixture at least 5 moles of chlorosulfur per mole of the phthalocyanine compound at a temperature of 70 to 150 ° C can act.



  <I> Example 1 </I> 23 parts of copper phthalocyanine, 15.6 parts of 95% hydroxylamine sulfate and 0.11 part of ammonium molybdate are stirred in 345 parts of chlorosulfonic acid at 115 for 2 hours. Then 40.5 parts of sulfur chloride are added dropwise within 10-15 minutes. This mixture is stirred for 1 hour at 115 and, after cooling to 30, poured into 5-6 times the amount of water.

   The dye, which is isolated in a known manner, dyes the textile fiber from a dull steel-blue sodium sulphide solution in greenish olive-gray shades of good fastness to washing and very good lightfastness.



  If the mixture is stirred with hydroxylamine not at 115 for 2 hours but at 105 for 3 hours under otherwise unchanged test conditions, a dye with a somewhat bluish cast and the same fastness properties is obtained.



  If you stir with chlorosulfur for 3 hours rather than 1 and otherwise work under the same conditions, you get a dye with practically the same properties.



  <I> Example 2 </I> 23 parts of copper phthalocyanine, 15.6 parts of 95% hydroxylamine sulfate and 0.11 part of ammonium molybdate are stirred in 345 parts of chlorosulfonic acid at 85 for 24 hours.

   Then 40.5 parts of sulfur chloride are added dropwise within 10-15 minutes. This mixture is stirred for 2 hours at 85 and, after cooling to about 30, is added dropwise to 5-6 times the amount of water. The dye, isolated in the usual way, dyes the textile fiber from dirty blue-green sodium sulphide solution in blue-tinged olive-gray shades of good washing fastness and very good lightfastness.



  If the 15.6 parts of 95% hydroxylamine sulphate used in this example are replaced by 25.9 parts of 91% acidic hydroxylamine sulphate (NH20H.H2SO4), a product is obtained with practically the same coloring properties.
