  Verfahren zur Herstellung eines Schwefelfarbstoffes.    Es     wurde        gefunden,        d@ass    man zu Wert  vollen     Schwefelfarbstoffen    gelangt,     wenn     man Mono- oder     Diamino,anthracene,    deren  am     Stickstoff    substituierte     Demivate,        insbe-          sondere    Mono- oder     DiaTylamino!anthracene,     Oder Monooder     Diarylamino.anthra:

  chino@ne,          odser        Kamoubstitutlonspro,dukte    aller dieser       Ausgaugskörper    in an sich     beik@amuter        Weisse     mit     echwefeluden        Miheih,    behandelt und, die  dabei     erhaltene    Rohschmelze in dem     üblichen          Weise        aufarbeitet.     



  Die o     erhaltenen    Farbstoffe     fäirben        die          pflanzliche    Faser, im     Gegensatz    zu den     bisher     aua     Anithracen    und seinen Derivaten durch  Einwirkung von Schwefel oder Chlorschwe  fel     erhaltenen        Farbstoffen,    die sich nur aus  der     Küpe    färben     lassen,    aus dem     Schwefel-          na,triumbade        ih        grauen,        grünsstichigen,

       Vorliegendes        Patent    bezieht sich nun auf  ein Verfahren zur     Henstellung        eines    Sohwe-         felfarbstoffes,        @dadurch    ,gekennzeichnet,     :dass;

       man     1-p-Tolwido,"anthra@ahimon    mit     einem          schwiefelnden        Mittel        behandelt        und        dhe        dabei          ,erhaltene        Rohschmelze    unter     Verwendung     von     Schw        ef@el@alkali        aufschliesst.     



  Der so erhaltene     Schwe:felfarbs        toff        isst    ein       dunkles        Pulver        und    färbt die     pflanzliche     Faser aus dem     Sehwe,felmatriumbad    in echten       ol'ivstichig    grauen Tönen,     inebesionidere        von.     einer     sehr    ,guten     tichteobttheit.     



       Beispiel:     Zu einer Schmelze von 12     Teilen        Schwefel     in 150     Teilen        Clil,orschwefel    werden .allmäh  lich 40     Teilte        1-p-Toluido-antbmaschihon    bei  70-80      eingetragen.    Man     heizt    langsam auf       15d ,    kocht 1     Stunde        unter        Rückfluss,    und       ,

  destilliert        @diann    bis     zur        Trockne.        Dann        wird          ,die        Tempemtur    auf 270  erhöht     und    8     Stun-          d:en        bei        @dieser        Temperatur        .gehalten.    Durch       Nachbehandlung        m;it        S,ohwefelna@xium    und.

  Process for the production of a sulfur dye. It has been found that sulfur dyes of full value can be obtained if mono- or diamino, anthracenes, their nitrogen-substituted derivatives, in particular mono- or dia-tylamino, anthracene, or mono- or diarylamino-anthra:

  chino @ ne, odser Kamoubstitutlonspro, products of all of these output bodies in per se beik @ amuter white with echulfuruden Miheih, treated and worked up the raw melt obtained in the usual way.



  The dyes obtained color the vegetable fiber, in contrast to the dyes previously obtained from anithracene and its derivatives by the action of sulfur or chlorosulfur, which can only be dyed from the vat, from the sulphurous, triumous bath with gray, green-tinged,

          brown to waxen color shades of good fastness properties, in particular a remarkable light fastness.



       The present patent now relates to a process for the preparation of a sulphurous dye, characterized in that: that;

       1-p-Tolwido, "anthra @ ahimon" is treated with a smoldering agent and that is, the crude melt obtained is digested using Schw ef @ el @ alkali.



  The sulfur dye thus obtained eats a dark powder and colors the vegetable fiber from the lake, felmatriumbad in real olive-tinged gray tones, inebesionidere from. a very, good music pleasure.



       Example: To a melt of 12 parts of sulfur in 150 parts of chloride, 40 parts of 1-p-toluido-antbmaschihon are gradually added at 70-80. Heat slowly to 15d, reflux for 1 hour, and,

  distilled @diann to dryness. Then the temperature is increased to 270 and held at this temperature for 8 hours. After treatment with S, ohwefelna @ xium and.

         Lye is added to the dye in the usual white.
