Description

  

  Verfahren zur Herstellung eines     sticlzstofhaltigen        5.6.7.8-Tetrahydro-          anthrachinonderivates.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Herstellung eines stickstoff  haltigen     5.6.7.8-Tetrahydroanthrachinon-          derivates,    welches darin besteht, dass man       Leuko-5.6.7.8-tetrahydrochinizarin    mit       Äthylamin    umsetzt und die     Leukoverbin-          dung    oxydiert.  



  Die so erhaltene neue Verbindung bil  det derbe, bronzeglänzende Kristalle vom       Schmelzpunkt    145 bis 146   C. Die Lösungs  farbe in konzentrierter     Schwefelsäure    ist  blaustichig rot, in organischen Lösungsmit  teln rein blau. Die Verbindung färbt     Ace-          tatseide    in blauen Tönen.  



  <I>Beispiel:</I>  Man erhitzt ein Gemisch von 26 Ge  wichtsteilen     Leuko-5    . 6 .     7.8-tetrahydrochin-          izarin,    160 Gewichtsteilen Äthylalkohol und  80 Gewichtsteilen einer 50     %    ixen     wässrigen          Äthylaminlösung    4 bis 5     Stunden    zum Sie  den. Dann leitet man 2 Stunden Luft durch  die Lösung. Das 1 .     4-Di-(äthylamino)-          5.6.7.8-tetrahydroanthrachinon    scheidet    sich in deren     bronzeglänzenden    Kristallen  schon in der     Hitze    aus.

   Es hat einen  Schmelzpunkt von 145 bis 146   C; die Lö  sungsfarbe in     konzentrierter    Schwefelsäure  ist blaustichig rot, in organischen Lösungs  mitteln     rein    blau. Auf     Acetatseide    erhält  man eine blaue Färbung.



  Process for the production of a nitrogen-containing 5.6.7.8-tetrahydro-anthraquinone derivative. The subject of this additional patent is a process for the production of a nitrogen-containing 5.6.7.8-tetrahydroanthraquinone derivative, which consists in reacting leuco-5.6.7.8-tetrahydroquinizarine with ethylamine and oxidizing the leuco compound.



  The new compound obtained in this way forms tough, shiny bronze crystals with a melting point of 145 to 146 C. The solution color in concentrated sulfuric acid is bluish red, in organic solvents it is pure blue. The connection dyes acetate silk in blue tones.



  <I> Example: </I> A mixture of 26 parts by weight of Leuko-5 is heated. 6th 7.8-tetrahydroquinizarin, 160 parts by weight of ethyl alcohol and 80 parts by weight of a 50% ixen aqueous ethylamine solution for 4 to 5 hours. Then air is passed through the solution for 2 hours. The 1st 4-Di- (äthylamino) - 5.6.7.8-tetrahydroanthraquinone separates in their shiny bronze crystals in the heat.

   It has a melting point of 145 to 146 C; the solution color in concentrated sulfuric acid is bluish red, in organic solvents it is pure blue. A blue coloration is obtained on acetate silk.
