Description

  

  Verfahren zur Darstellung eines Farbstoffes.    Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Darstellung eines     Parb-          stoffes,    welches dadurch gekennzeichnet ist,  dass man die     aus    2     Mol        Aminochrysen    vom  Schmelzpunkt 206-207   C und 1     Mol        1.4-          Benzochinon    durch Erhitzen in Alkohol und  durch weiteres Erhitzen in einem hochsieden  den Lösungsmittel erhältliche Verbindung  mit einem     Sulfonierungsmittel    behandelt.  



  <I>Beispiel:</I>  10 Gewichtsteile des Farbstoffes folgen  der wahrscheinlicher Formel  
EMI0001.0010     
    der, wie oben angegeben erhältlich ist, wer  den in 100 Gewichtsteilen Monohydrat gelöst.  Bei 20-25 o lässt man 100 Gewichtsteile  20      /oiges        Oleum    zuliessen und rührt eine       Stunde    nach.

   Man gibt auf Eis und saugt  die ausgeschiedene     Sulfosäure    ab, wäscht mit  Kochsalzlösung neutral und trocknet. -Die       Sulfosäurc    ist in     Wasser    mit blauer Farbe  löslich     und    färbt die tierische, pflanzliche  und Kunstfaser, sowie gemischte Gewebe in       grünstichig    blauen Tönen mit hervorragenden  Echtheitseigenschaften an. .  



  An Stelle des     Oleums    können auch andere  der     bekannten        Sulfierungsmittel    verwendet  und gleichfalls können andere Reaktions  temperaturen gewählt werden.



  Process for the preparation of a dye. The subject of the present patent is a process for the preparation of a parbo- stoff, which is characterized in that the 2 mol aminochryses with a melting point of 206-207 C and 1 mol 1,4-benzoquinone by heating in alcohol and by further heating in a high boiling point Solvent-available compound treated with a sulfonating agent.



  <I> Example: </I> 10 parts by weight of the dye follow the more likely formula
EMI0001.0010
    which, as indicated above, is available who dissolved the monohydrate in 100 parts by weight. At 20-25 °, 100 parts by weight of 20% oleum are allowed to admit and the mixture is stirred for a further hour.

   It is poured onto ice and the sulfonic acid which has separated out is filtered off with suction, washed neutral with sodium chloride solution and dried. -The sulfonic acid is soluble in water with a blue color and stains animal, vegetable and synthetic fibers as well as mixed fabrics in greenish blue tones with excellent fastness properties. .



  Instead of the oleum, other known sulfonating agents can also be used, and other reaction temperatures can also be selected.

PATENTANSPRUCH: Verfahren zur Darstellung eines Farb stoffes, dadurch gekennzeichnet, dass man die aus 2 Alol Aminochrysen vom Schmelzpunkt 206-207 o C und 1 Mo1 1.4-Benzochinon durch Erhitzen in Alkohol und durch weiteres Er hitzen in einem hochsiedenden Lösungsmittel erhältliche Verbindung mit einem Sulfonie- rungsmittel behandelt. Die Sulfosäure ist in Wasser mit blauer Farbe löslich und färbt die tierische, pflanz liche und Kunstfaser, sowie gemischte Ge webe in grünstichig blauen Tönen mit her vorragenden Echtheitseigenschaften an. PATENT CLAIM: Process for the preparation of a dye, characterized in that the compound obtained from 2 Alol aminochryses with a melting point of 206-207 o C and 1 Mo1 1,4-benzoquinone by heating in alcohol and by further heating in a high-boiling solvent is obtained with a sulfonic acid - treated means. The sulphonic acid is soluble in water with a blue color and stains animal, vegetable and synthetic fibers as well as mixed fabrics in greenish blue tones with excellent fastness properties. UNTERANSPUUCE Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man die Sulfierung mit einem Gemisch von Monohydrat und 20 oloigem Oleum bewirkt. SUBSEQUENT PROCESS according to claim, characterized in that the sulphonation is effected with a mixture of monohydrate and oleaginous oleum.
