Description

  

      \'erfahren    zur Darstellung eines sauren Wollfarbstoffes der     Anthr        achinonr    eilte.    Gegenstand vorliegenden Zusatzpatentes  ist ein Verfahren zur Darstellung eines sauren       )Vollfarbstoffes    der     Anthrachinonreihe.    das  dadurch gekennzeichnet ist, dass man 1     Mol     1. .     5-Dichloranthrachinon    mit 2     Mol        1-Amino-          4-cy        clohexylbenzol    zur Umsetzung bringt  und den so erhaltenen Stoff     sulfiert.     



  <I>Beispiel:</I>  8,4 Gewichtsteile 1. . 5 -     Dichloranthra-          chinon    werden mit 60 Gewichtsteilen 1  Amino-4-cyclohexylbenzol und 4 Gewichts  teilen     Natriumacetat    5 Stunden auf<B>190'</B> er  hitzt. Durch Verdünnen mit Methanol schei  det sich das     Kondensationsprodukt    in rot  braunen Blättchen vom Schmelzpunkt 304  bis 305   ab. In konzentrierter Schwefel  säure ist der Farbstoff farblos löslich. Der  Farbstoff wird mit zirka.     5%igem        Oleum          sulfiert.    Die so erhaltene     Disulfosäure    färbt  Wolle aus saurem Bade in violetten Tönen.

    Die Färbungen besitzen eine sehr gute  Wasch- und     Walkechtheit.  



      \ 'Learned about the representation of an acidic wool dye which Anthr achinonr hurried. The subject of the present additional patent is a process for the preparation of an acidic full dye of the anthraquinone series. which is characterized in that 1 mole of 1.. Bringing 5-dichloroanthraquinone with 2 moles of 1-amino-4-cy clohexylbenzene to the reaction and sulfating the substance thus obtained.



  <I> Example: </I> 8.4 parts by weight 1.. 5- dichloroanthraquinone are heated to <B> 190 '</B> for 5 hours with 60 parts by weight of 1 amino-4-cyclohexylbenzene and 4 parts by weight of sodium acetate. By diluting with methanol, the condensation product separates out in red-brown flakes with a melting point of 304 to 305. The dye is colorlessly soluble in concentrated sulfuric acid. The dye is approx. 5% oleum sulfated. The disulfonic acid obtained in this way dyes wool from an acid bath in purple tones.

    The dyeings have very good wash and milled fastness.
