Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 161566.    Verfahren zur Darstellung eines Farbstoffes der     Anthraehinonreilre.       Gegenstand vorliegenden Zusatzpatentes  ist ein Verfahren zur Darstellung eines Farb  stoffes der     Anthrachinonreihe,    welches da  durch gekennzeichnet ist, dass man 2     Mol          Äthylenoxyd    auf 1     Mol        1-Amirro-4-(p'-amirro-          plreiiyl)-aminoanthrachirrorr    einwirken lässt.

    <I>Beispiel</I>  In eine     Suspension    von 100 Gewichtsteilen  einer 20      /oigerr    Paste des     1-Arrrino-4-(p'-amino-          pher)yl)-aminoanthr-aclrirrorrs    in 250 Gewichts  teilen Wasser wird bei 50   C 1'/2 bis 2 Stunden       Äthylerloxyd    eingeleitet. Man filtriert dann  ab und wäscht mit Wasser nach. Der er  haltene Farbstoff ist neu und liegt gleich in  zum Färben geeigneter     Pastenform    vor und  färbt     Acetatseide    in stahlblauen, äusserst  kräftigen Tönen an.



  <B> Additional patent </B> to the main patent no. 161566. Process for the preparation of a dye of the Anthraehinonreilre. The present additional patent is a process for the preparation of a dye of the anthraquinone series, which is characterized by the fact that 2 moles of ethylene oxide are allowed to act on 1 mole of 1-amirro-4- (p'-amirroplreiiyl) -aminoanthrachirrorr.

    <I> Example </I> In a suspension of 100 parts by weight of a 20% paste of 1-arrrino-4- (p'-aminopher) yl) -aminoanthr-aclrirrorrs in 250 parts by weight of water is added at 50 C. '/ 2 to 2 hours of ethyl oxide introduced. It is then filtered off and washed with water. The dye obtained is new and comes in a paste form suitable for dyeing and dyes acetate silk in extremely strong shades of steel blue.
