Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 113867.         Verfahren    zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen     Azofarb-          stoff,    der in seinem     Molekül    einen     Cyanurkern     enthält, erhalten kann, wenn man 1     Mol.    des       diazotierten    Kondensationsproduktes aus     11M1.          m-Toliiylendiamici    und 1     Mol.        Cyanurtricar-          bonsäurechlorid    mit 1     Mol.        2,

  5-Aininonaphthol-          7-sulfosäure    kuppelt. Der neue Farbstoff bil  det ein oranges Pulver und färbt Wolle in  orangen Tönen an.  



  <I>Beispiel</I>  31,7 Teile des Kondensationsproduktes aus       m-Toluylendiamin    und     Cyanurtricarbonsäure-          chlorid    werden wie üblich     diazotiert    und zu  einer Lösung von 26,1 Teilen     2,5-Amino-          iiaplithol-7-sulfosaures    Natrium und 25 Teilen    Soda gegeben. Der gebildete     Farbstoff    wird  wie üblich mit Kochsalz gefällt, filtriert und  getrocknet.



  <B> Additional patent </B> to main patent no. 113867. Process for the production of a new azo dye. It has been found that an azo dye which contains a cyanuric nucleus in its molecule can be obtained if 1 mol. Of the diazotized condensation product from 11M1. m-Toliiylendiamici and 1 mol. Cyanurtricar- bonsäurechlorid with 1 mol. 2,

  5-Ainonaphthol-7-sulfonic acid couples. The new dye forms an orange powder and dyes wool in orange tones.



  <I> Example </I> 31.7 parts of the condensation product of m-tolylenediamine and cyanurotricarboxylic acid chloride are diazotized as usual and form a solution of 26.1 parts of 2,5-aminoaplithol-7-sulphonic acid sodium and 25 parts Given soda. The dye formed is precipitated as usual with common salt, filtered and dried.
