Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 110287.         Verfaluen    zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen       Farbstoff    erhält, wenn man die dianotierte       3-Amirionaphtbalin-1,8-dikarbonsäure    mit 1       (2-Chlor-5-sulfo)-phenyl-5-pyrazolon-3-karbon-          säufe    kuppelt. Der neue     Farbstoff    bildet ein  rotes Pulver, das sieh in Wasser und in  Schwefelsäure mit rotgelber Farbe löst.

   Er  färbt Wolle aus saurem Bade in     reingelben     Tönen, welche beim     Nachchromieren        reingelb     bleiben und sehr echt, insbesondere     potting-          echt    werden. Im Chromdruck erzeugt er  echte,     rötlichgelbe    Töne.         eispiel:       10,6 Teile     3-Aminonaphthalin-1,8-dikar-          bonsäureanhydrid    werden mit Hilfe von 10  Teilen 30     0%iger    Natronlauge und 150 Teilen  Wasser heiss gelöst, nach Abkühlung auf  zirka 20   mit 30 Teilen Eis und 25 Teilen  30  /o     iger    Salzsäure versetzt.

   Es scheidet  sich die     3-Aminonaphtbalin-1,8-dikarbonsäure     aus, welche auf Zusatz von 3,5 Teilen Nitrit  zunächst in Lösung geht, um bald wieder  als     Diazoverbindung    auszufallen. Die so er-         haltene    Suspension wird in eine alkalische  Lösung von 15,9 Teilen     1-(2-Chlor        5-sulfo)-          phenyl-5-pyrazolon-3-karbonsäure    einlaufen  gelassen. Nach beendeter Kupplung wird  das überschüssige Alkali mit Säure abge  stumpft, der     Farbstoff        ausgesalzen,    filtriert  und getrocknet.



  <B> Additional patent </B> to main patent no. 110287. Procedure for the production of a new dye. It has been found that a new dye is obtained when the dianotated 3-amirionaphthaline-1,8-dicarboxylic acid is coupled with 1 (2-chloro-5-sulfo) -phenyl-5-pyrazolone-3-carbon acid. The new dye forms a red powder that dissolves in water and sulfuric acid with a red-yellow color.

   It dyes wool from an acid bath in pure yellow tones, which remain pure yellow when they are chrome-plated and become very real, especially potting-real. In the chrome print it creates real, reddish yellow tones. Example: 10.6 parts of 3-aminonaphthalene-1,8-dicarboxylic anhydride are dissolved with the aid of 10 parts of 30% strength sodium hydroxide solution and 150 parts of hot water, after cooling to about 20 with 30 parts of ice and 25 parts of 30% added hydrochloric acid.

   The 3-aminonaphtbalin-1,8-dicarboxylic acid separates out, which, upon addition of 3.5 parts of nitrite, initially dissolves and soon precipitates again as a diazo compound. The suspension thus obtained is allowed to run into an alkaline solution of 15.9 parts of 1- (2-chloro 5-sulfo) phenyl-5-pyrazolone-3-carboxylic acid. After the coupling has ended, the excess alkali is blunted with acid, the dye is salted out, filtered and dried.

PATENT CLAIM: Process for the production of a new dye, characterized in that the dianotated 3-aminonaphthalene-1,8-dicarboxylic acid is coupled with 1- (2-chloro-5-sulfo) -phenyl-5-pyrazolone-3-carboxylic acid. The new dye forms a red powder that dissolves in water and sulfuric acid with a red-yellow color. He dyes wool from an acid bath in pure yellow tones, which remain pure yellow when the ears are rewritten, and become very real, especially potting. Im Chrom druck erzeugt er echte, rötlichgelbe Töne. With chrome printing, it creates real, reddish yellow tones.
