Description

  

  Verfahren zur Herstellung eines Farbstoffes der     Azinreihe.       Gegenstand des vorliegenden Patentes  ist die Herstellung eines Farbstoffes der       Naphthophenazinreihe.        Dran    erhält denselben       dadurch,    dass man auf ein Gemisch aus der       4.4'-Dianiino-3'-methyldiplienylamin-2-sulfori-          säure    und     1.3-Dianilirioriaphthaliri-8-sulfon-          säure    in einem Verdünnungsmittel ein Oxyda  tionsmittel einwirken lässt.

      <I>Beispiel:</I>    390 Gewichtsteile 1.     3-Dianilinonaphthalin-          8-sulfonsäure    und 293 Gewichtsteile     4.4'-Di-          amirio-3'-methyl-diphenylamin-2-sulfonsäure          werden        mit        7000        Gewichtsteilen        50        %        igen     Alkohols und wenig Ammoniak in schwach  alkalische Lösung gebracht und durch diese  Lösung bei 35-400 C Luft geleitet.

   Nach  beendeter     Farbstoffbildung    wird auf 600 C       erwärmt,    mit 350 Gewichtsteilen Kochsalz  versetzt und kalt gerührt. Der Farbstoff wird  abgesaugt, mit einer mit Kochsalz gesättigten         50        %        igen        Spritlösung        gewaschen        und        ge-          trocknet.    Man erhält ein bronzeglänzendes  Kristallpulver, das in Wasser mit blauer, in  konzentrierter Schwefelsäure mit grünblauer  Farbe löslich ist. Der Farbstoff färbt Wolle  und Seide     grünstichig    blau.

   Die Färbungen  auf Wolle sind gut wasch-, walk-,     seewasser-,          alkali-    und lichtecht, die Färbungen auf  Seide wasch- und wasserecht. Alle Färbun  gen haben auch sehr gute Abendfarbe.



  Process for the preparation of an azine series dye. The subject of the present patent is the preparation of a dye of the naphthophenazine series. The same is obtained by allowing an oxidizing agent to act on a mixture of 4,4'-dianiino-3'-methyldiplienylamine-2-sulforic acid and 1,3-dianilirioriaphthalenic-8-sulphonic acid in a diluent.

      <I> Example: </I> 390 parts by weight of 1,3-dianilinonaphthalene-8-sulfonic acid and 293 parts by weight of 4,4'-di-amirio-3'-methyl-diphenylamine-2-sulfonic acid are mixed with 7000 parts by weight of 50% alcohol and little Ammonia was brought into a weakly alkaline solution and air was passed through this solution at 35-400 C.

   When the dye has formed, the mixture is heated to 600 ° C., mixed with 350 parts by weight of sodium chloride and stirred while cold. The dye is filtered off with suction, washed with a 50% strength spray solution saturated with sodium chloride and dried. A bronze-shining crystal powder is obtained which is soluble in water with a blue color and in concentrated sulfuric acid with a green-blue color. The dye dyes wool and silk a greenish blue.

   The dyeings on wool are washable, milled, seawater, alkali and lightfast, the dyeings on silk are washable and waterfast. All colors also have a very good evening color.
