  Verfahren zur Herstellung eines neuen     Küpenfarbstoffes.       Die vorliegende Erfindung betrifft ein  Verfahren zur     Herstellung    eines neuen     Kü-          penfa.rb.stoffes,    welches dadurch gekennzeich  net ist, dass     2-Amino-3,4-phthaloylacridon     mit     p-n-Butyl,sulfonylbenzoylchlori.d    bis zur  Bildung von     2-p-n-Butylsulfonyl-benzoyl-          amino-3,4-phthaloylacridon        acyliert    wird.  



  Der neue Farbstoff entspricht der fol  genden Formel:  
EMI0001.0010     
    Der     neue.    Farbstoff     ist    ein dunkelblaues,  festes Produkt, welches in     Wasser    unlöslich  ist, in     Schwefelsäure    eine     orangegefärbte    Lö  sung ergibt und Baumwolle aus einer violet  ten     Küpe    in hellen,     grünlichblauen    Tönen  färbt.

      <I>Beispiel:</I>  Ein     Gemisch    von 70, Teilen     p-n-Butyl-          s.u,Ifonyl-benzoylchlorid,    1000 Teilen trocke  nem Nitrobenzol, 70 Teilen     2-Amino-3,4-          phthaloylacridon    und 1 Teil     Pyridin    wird  während 3 Stunden unter Rühren auf<B>160</B> bis  1G5  C erhitzt und hierauf gekühlt     und    fil  triert. Der Rückstand wird mit Benzol und       Äthylalkohal    gewaschen und hernach ge  trocknet.

   Dabei erhält man das     2-p-n-Butyl-          sulfonyl        -benzoylamino        -3,4-phthaloylaeridon,     welches Baumwolle aus einer violetten, alka  lischen     Natriumhydrosulfitküpe    in     hellen,          grünlichblauen    Farbtönen färbt.



  Process for the production of a new vat dye. The present invention relates to a process for the production of a new Küpenfa.rb.stoffes which is characterized in that 2-amino-3,4-phthaloylacridone with pn-butyl, sulfonylbenzoylchlori.d to the formation of 2-pn- Butylsulfonyl-benzoyl-amino-3,4-phthaloylacridone is acylated.



  The new dye corresponds to the following formula:
EMI0001.0010
    The new. Dye is a dark blue, solid product, which is insoluble in water, produces an orange solution in sulfuric acid and dyes cotton from a violet vat in light, greenish-blue tones.

      <I> Example: </I> A mixture of 70 parts of pn-butyl-su, ifonyl-benzoyl chloride, 1000 parts of dry nitrobenzene, 70 parts of 2-amino-3,4-phthaloylacridone and 1 part of pyridine is used for 3 hours Heated to <B> 160 </B> to 1G5 C with stirring, then cooled and filtered. The residue is washed with benzene and ethyl alcohol and then dried.

   This gives 2-p-n-butylsulfonyl-benzoylamino -3,4-phthaloylaeridone, which dyes cotton from a violet, alkaline sodium hydrosulfite vat in light, greenish-blue shades.
