  Verfahren zur Herstellung eines     Anthraehinonfarbstoffes.       Es     wurde    gefunden,     dass.    man     einen    neuen       Anthrachinonfarbstoff        erhält,    wenn man     1,4-          Di-(y-Chlorr-,p-oxypropylamina)

  -anthraehnon     in     Gegenwart        eines        mit        Wasser        mischbaren          Lösungsmittels    und von Wasser mit     Natrium-          thiosulfat        uams@etzt.     



       Dem    so erhaltene     Farbstoff        bildet        eine          gallertartige    Masse von     tiefblauer    Farbe. Er  färbt Wolle in     kräftigen,        reinen    blauen  Tönen von guten     Echtheitseigenschaften    und  eignet sich auch zum Bedrucken von     Acetat-          kunstselde.     



  <I>Beispiel:</I>  2.0 Teile     1,4-Di-        (y-Chlor-ss-ogypropyl-          amino)-anthracIiinon    werden in 650     Teilen     Methylalkohol     und    350     Teilen    Wasser mit  20     Teilen.        Natriumthosulfat        eine    Stunde auf  <B>150'</B>     erhitzt.    Der Methylalkohol     wird    ab-         destilliert,

          worauf        eine        tiefblaue!     Lös     ung        erhalten        wird,    die beim     Erzkalten    zu       einer        Galle        emtaxzrt.  



  Process for the preparation of an anthraquinone dye. It has been found that a new anthraquinone dye is obtained if 1,4-di- (y-chloro-, p-oxypropylamina)

  -anthraehnone in the presence of a water-miscible solvent and water with sodium thiosulfate uams @ etzt.



       The dye thus obtained forms a gelatinous mass of deep blue color. It dyes wool in strong, pure blue tones with good fastness properties and is also suitable for printing on acetate artificial selde.



  <I> Example: </I> 2.0 parts of 1,4-di- (γ-chloro-ss-ogypropyl-amino) -anthracIinon are in 650 parts of methyl alcohol and 350 parts of water with 20 parts. Sodium thosulphate heated to <B> 150 '</B> for one hour. The methyl alcohol is distilled off,

          what a deep blue one! Solution is obtained which, when it is ore cold, emtaxzrt to a gall.
