  Zusatzpatent zum Hauptpatent     Nr.   <B>182053.</B>    Verfahren zur Darstellung eines     Farbstoffes    der     Dioxazinreihe.       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Darstellung eines       Parbstoffes    der     Dioxazinreihe,    welches da  durch gekennzeichnet ist,     dass    man<B>1</B>     Mol          Chloranil    mit 2     Mol        3-Aminodiphenylenoxyd     bei einer Temperatur, die unter etwa 120'<B>C</B>  liegt, kondensiert und die so erhaltene Zwi  schenverbindung bei einer Temperatur, die  über etwa 120<B>0</B>     C    liegt,

   in Gegenwart eines  Lösungsmittels weiter kondensiert.    <I>Beispiel:</I>    <B>18,3</B> Gewichtsteile     S-Aminodiphenylerioxyd     werden in<B>350</B> Gewichtsteilen Alkohol mit  14 Gewichtsteilen     Ohloranil    und<B>10</B> Gewichts  teilen     Natriumacetat    2 Stunden zum Sieden  erhitzt. Nach dem Erkalten saugt man das  braune Kondensationsprodukt; ab und wäscht  mit Alkohol und Wasser nach.  



  <B>10</B> Gewichtsteile des so erhaltenen Zwi  schenproduktes werden in<B>150</B> Gewichtsteilen  Nitrobenzol unter Zusatz von<B>3</B> Gewichts  teilen     p-Toluolsulfochlorid   <B>1</B> Stunde     züm    Sie-    den erhitzt. Nach dem Abkühlen auf<B>100 0</B>  saugt man ab und wäscht mit Nitrobenzol  nach. Das in Nadeln kristallisierte Reaktions  produkt löst sich in     Monobydrat    mit blauer  Farbe und stellt, in feine Verteilung gebracht,  ein rubinfarbenes Pigment dar.



  Additional patent to main patent no. <B> 182053. </B> Process for the preparation of a dye of the dioxazine series. The subject of the present additional patent is a process for the preparation of a paraffin of the dioxazine series, which is characterized in that <B> 1 </B> moles of chloranil are mixed with 2 moles of 3-aminodiphenylene oxide at a temperature below about 120 'B > C </B> is, condenses and the intermediate compound thus obtained at a temperature that is above about 120 <B> 0 </B> C,

   condensed further in the presence of a solvent. <I> Example: </I> <B> 18.3 </B> parts by weight of S-aminodiphenyl oxide are divided into <B> 350 </B> parts by weight of alcohol with 14 parts by weight of ohloranil and <B> 10 </B> weight Sodium acetate heated to boiling for 2 hours. After cooling, the brown condensation product is sucked off; and washes with alcohol and water.



  <B> 10 </B> parts by weight of the intermediate product obtained in this way are converted into <B> 150 </B> parts by weight of nitrobenzene with the addition of <B> 3 </B> parts by weight of p-toluenesulfochloride <B> 1 </B> Heated to the boil for an hour. After cooling to <B> 100 0 </B>, it is suctioned off and washed with nitrobenzene. The reaction product crystallized in needles dissolves in monobydrate with a blue color and, when finely divided, is a ruby-colored pigment.

UNTERANSPRüCHE: <B>1.</B> Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man die Kondensation unter etwa 120<B>0</B> C durch Sieden der Re aktionskomponenten in Alkohol in Gegen wart von Natriumacetat bewirkt. 2. The dioxazine compound thus obtainable crystallizes in needles which dissolve in sulfuric acid monohydrate with a blue color. The compound represents a ruby-colored pigment when it is finely distributed. SUBClaims: <B> 1. </B> Method according to patent claim, characterized in that the condensation is carried out below about 120 <B> 0 </B> C. The reaction components boil in alcohol in the presence of sodium acetate. 2. Verfahren nach Patentanspruch, 'dadurch gekennzeichnet, dass man die Kondensation über etwa 1201 C derart bewirkt, dass man das Zwischenprodukt in Nitrobenzol in Gegenwart von p-Toluolsulfochlorid zum Sieden erhitzt. Process according to patent claim, characterized in that the condensation is effected above about 1201 C in such a way that the intermediate product is heated to the boil in nitrobenzene in the presence of p-toluenesulfonyl chloride.
