Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>131100.</B>    Verfahren zur Herstellung eines neuen, als Farbstoff verwendbaren Produktes.    Es wurde gefunden,     dass    man ein neues  Produkt erhält, wenn man     Benvaldehyd,          Bistilfit    und das technische Gemisch eines  Salzes der     1,5-Diamino-4,8-dioxy-    und     1,8-          Diamino-4,5-dioxyanthrachitiori-2-sulfosäure     aufeinander einwirken     lässt.     



  Das neue Produkt bildet, in trockenem  Zustande ein dunkelblaues, in Wasser leicht  mit     reinblauer    Farbe lösliches Pulver. Es  eignet sich in hervorragender Weise zum Be  drucken von     Acetatseide.     



  <I>Beispiel:</I>  4 Teile eines technischen Gemisches von       1,5-diamino-4,8-dioxy-    und     1,8-diamino-4,5-          dioxyanthrachinon-2-sulfosaurem    Natrium wer  den mit<B>16</B> Teilen Wasser     zn    einem     bomo-          genen    Teig angerührt, mit<B>16</B> Teilen einer  zirka     40-volumprozentigen        Natriumbisulfit-          lösung    und 4 Teilen     Benzaldehyd    versetzt  und unter Rühren so lange auf Wasserbad-         temperatur    erwärmt, bis keine weitere Än  derung der Lösungsfarbe mehr zu konstatieren  ist.

   Man dampft zur     Trocke    ein.



  Additional patent to main patent no. <B> 131100. </B> Process for the production of a new product that can be used as a dye. It has been found that a new product is obtained if benvaldehyde, bistilfit and the technical mixture of a salt of 1,5-diamino-4,8-dioxy- and 1,8-diamino-4,5-dioxyanthrachitiori-2- allows sulfonic acid to act on each other.



  When dry, the new product forms a dark blue powder which is easily soluble in water with a pure blue color. It is ideal for printing acetate silk.



  <I> Example: </I> 4 parts of a technical mixture of 1,5-diamino-4,8-dioxy and 1,8-diamino-4,5-dioxyanthraquinone-2-sulfonic acid sodium with <B> 16 parts water are mixed into a curved dough, mixed with 16 parts of an approximately 40 percent by volume sodium bisulfite solution and 4 parts benzaldehyde and heated to water bath temperature with stirring until no further change in the color of the solution can be detected.

   One evaporates to dryness.
