Description

  

      Zusatzpatent    zum Hauptpatent Nr. 100705.         Verfahren    zur Herstellung eines neuen     indigoiden    Farbstoffes.    Es wurde gefunden,     da.ss    ein neuer, wert  voller,     indigoider    Farbstoff entsteht, wenn  man das 5 -     Brom-2,1-naphthioindoxyl    mit       Acenaphthenchinon        kondensiert.     



  Der neue     Farbstoff    stellt     ein.    rotes Pulver  dar, das     sich    in     Schwefelsäure    mit blauer  Farbe löst. Er bildet eine braune     Küpe    und  färbt     Baumwolle    in     orangebraunen    Tönen  von sehr .guter Echtheit.  



       Bespiel:     279 Teile     5-Brom-2,1-naphththioindioxyl     und 182 Teile     Acenaphthenchinon    werden in  5000 Teilen Alkohol     suspendiert    und zum  Sieden     erhitzt.    Dann gibt man 5 Teile kon  zentrierte Salzsäure zu. Nach     kurzem    Ko-         elfen    ist die Kondensation beendigt. Es wird  heiss filtriert,     gewaschen    und getrocknet.



      Additional patent to main patent no. 100705. Process for the production of a new indigoid dye. It has been found that a new, valuable, indigoid dye is formed when 5-bromo-2,1-naphthioindoxyl is condensed with acenaphthenquinone.



  The new dye sets. red powder that dissolves in sulfuric acid with a blue color. It forms a brown vat and dyes cotton in orange-brown shades of very good fastness.



       Example: 279 parts of 5-bromo-2,1-naphththioindioxyl and 182 parts of acenaphthenquinone are suspended in 5000 parts of alcohol and heated to the boil. Then 5 parts of concentrated hydrochloric acid are added. After a short kettle, the condensation is over. It is filtered hot, washed and dried.
