Description

  

  Verfahren zur Darstellung eines     Ogazins    der     Anthrachinonreihe.       Gegenstand des vorliegenden Zusatz  patentes ist ein Verfahren zur Darstellung  eines     Oxazins    der     Anthrachinonreihe,    welches  dadurch     gekennzeichnet    ist,

   dass man     1-jod-          anthrachinon-2-sulfosaures        Natrium    mit 3  amino - 4 -     oxydiphenylsulfon-ss'-sulfosaurem     Natrium in Gegenwart eines säurebindenden  Mittels kondensiert und das     Kondensations-          produkt        bis    zum Eintritt     einer    weiteren       Sulfrngruppe        srulfiert.       <I>Beispiel:

  </I>    56     Gewichtsteile        1-jodanthrachinon-2-sul-          fosaures    Natrium, 40 Gewichtsteile     3-amino-          4-oxydiphenylsulfon-3'-sulfosaures    Natrium,       2ä        Gewichtstele        Natriumca"rbonat,    1<B>,</B>5 Ge  wichtsteile     Natriumbicarbonat,    2 Gewichts  teile     gupferchlorür    und 700 Gewichtsteile  Wasser     werden    5     Stunden    bei 60 bis 65   C  gerührt. Nach dem Erkalten wird das aus  geschiedene     Kondensationsprodukt    abgesaugt  und mit Wasser ausgewaschen.

   In das so er-         haltene    Kondensationsprodukt wird zur Ver  besserung seiner Wasserlöslichkeit eine wei  tere     Sulfogruppe    eingeführt. Zu diesem  Zweck wird das getrocknete Produkt     in    der       zehnfachen    Gewichtsmenge 5 %     igen        Oleums     so lange bei 15 bis 20   C gerührt, bis     eine    in  Wasser gegossene Probe leicht löslich gewor  den ist. Ist dies der Fall, so wird auf Wasser  gegossen, abgesaugt,     mit    verdünnter     Koch-          salzlösung    neutral gewaschen und getrocknet.

         Man    erhält ein violettes Pulver, welches aus  saurem Bade Wolle     in        violetten    Tönen färbt.



  Process for the preparation of an ogazine of the anthraquinone series. The subject of the present additional patent is a process for the preparation of an oxazine of the anthraquinone series, which is characterized by

   that 1-iodo-anthraquinone-2-sulphonic acid is condensed with 3-amino-4-oxydiphenylsulphone-ss'-sulphonic acid sodium in the presence of an acid-binding agent and the condensation product is sulphated until a further sulphon group enters. <I> example:

  56 parts by weight of 1-iodanthraquinone-2-sulphonic acid, 40 parts by weight of 3-amino-4-oxydiphenylsulphone-3'-sulphonic acid sodium, 2 parts by weight of sodium carbonate, 1, 5 ge parts by weight of sodium bicarbonate, 2 parts by weight of gupferchlorur and 700 parts by weight of water are stirred for 5 hours at 60 to 65 ° C. After cooling, the condensation product which has separated out is filtered off with suction and washed out with water.

   A further sulfo group is introduced into the condensation product obtained in this way to improve its solubility in water. For this purpose, the dried product is stirred in ten times the weight of 5% oleum at 15 to 20 C until a sample poured into water is easily soluble. If this is the case, it is poured onto water, filtered off with suction, washed neutral with dilute sodium chloride solution and dried.

         A violet powder is obtained which dyes wool in violet shades from an acid bath.

PATENANSPRUCH Verfahren zur Darstellung eines Oxazins der Anthrachinonreihe, dadurch gekennzeich net, dass man 1-jodanthrachinon-2-sulfosaures Natrium mit 3-amino-4-oxydiphenylsulfon- 3'-sulfosaurem Natrium in Gegenwart eines säurebindenden Mittels 'kondensiert und das Kondensationsprodukt bis zum Eintritt einer weiteren Sulfogruppe sulfiert. Die so erhaltene I'arbs@toffdisulfosäure ist ein violettes Pulver, welches Wolle aus saurem Bade in violetten Tönen färbt. Claim process for the preparation of an oxazine of the anthraquinone series, characterized in that 1-iodanthraquinone-2-sulfonic acid sodium is condensed with 3-amino-4-oxydiphenylsulfone-3'-sulfonic acid sodium in the presence of an acid-binding agent and the condensation product is condensed until it occurs another sulfo group sulfated. The so obtained I'arbs @ toffdisulfonic acid is a violet powder which dyes wool from an acid bath in violet shades. UNTERANTSPRüCHE 1.
