  Verfahren zur Herstellung eines     hochsnbstantiven        2,3-Ogynaphthoesäurearylids.       Es     wurde    gefunden, dass man durch Kon  densation von     2,3rOgynaphthoesäure    mit  2 -     Amino    - 3 -     alkogydiphenylenogyden    oder  ihren     Substitutiomprodukten    zu     2,3-Ogy-          naphthoesäurearyliden    gelangt, die sich als  Grundierungen in der     Eisfärberei        durch    be  merkenswerte Eigenschaften auszeichnen.

   Sie  zeigen in alkalischer Lösung gegenüber  pflanzlichen     Fasern    eine     sehr    hohe     Substan-          tivi.tät,    so dass die     Grundierungsbäder    prak  tisch weitgehend erschöpft werden.

   Derartige  Kochsubstantive     Grundierungen        sind    zwar       bereits        aus    den deutschen     Patentschriften     Nr. 556477     und.    572473     bekannt    geworden,  doch zeichnen sich die nach dem vorliegen  den Verfahren erhältlichen     Arylide    vor die  sen bekannten Grundierungen     überTa;schender-          weise    durch eine viel bessere Löslichkeit aus.

    Sie neigen insbesondere nicht zur Hydrolyse,  was bei .den bisher bekannten Kochsubstan  tiven     2,3-Ogynaphthoesäurearyliden    durch  Verwendung von viel Natronlauge zum    Lösen und langes     Stehenlassen    .der Lösung  mit     Formaldehyd    einigermassen verhindert  werden konnte. Infolge ihrer einfacheren       Handhabung        stellen        die    nach dem vor  liegenden Verfahren erhältlichen     Farbstoff-          zwischenprodukte    eine wesentliche Bereiche  rung der     Technik    dar.  



  Gegenstand des vorliegenden Patentes ist  ein Verfahren zur     Herstellung    eines     hoch-          substantiven    2,3 -     Ogynaphthoesäurearylids,     welches dadurch     gekennzeichnet        ist,        .dass    man       2,3-Ogynaphthoesäure    mit     2-Amino-3-me-          thogyydiphenylenogyd        kondensiert.       <I>Beispiel:

  </I>    98     Gewichtsteile        2,3-Ogynaphthoesäure     werden mit 108     Gewichtsteilen        2-Amino-3-          methogydiphenylenogyd    vom     F.92-93'    C,  das zum Beispiel in der Weise erhältlich ist,       dass    man     3-Methogydiphenylenogyd        nitriert     und die erhaltene     Nitroverhindung    zu der  entsprechenden     Aminoverbindung        reduziert,         und<B>1000</B> Gewichtsteilen Chlorbenzol unter  Rühren auf<B>80'</B> C erwärmt.

   Man lässt bei  dieser Temperatur langsam 30     Gewichtsteile          Phosphortri.chlorid        eintropfen    und erhitzt  dann mehrere Stunden zum Sieden. Man  trennt heiss von der abgeschiedenen     phos-          phorigen    Säure und lässt die     Chlorbenzol-          lösung        erkalten,        wobei    das Kondensations  produkt fast vollkommen auskristallisiert.

    Das erhaltene     2-(2',3'-Oxyna.phthoylamino)-          3-methoxydiphenylenoxyd    kann mit wesent  lich weniger Natronlauge und Formaldehyd  zur Herstellung einer stabilen     Grundierungs-          lösung    verwendet werden als     beispielsweise     das     4-(2',3'-Oxyna.phthoylamino)-diphenyl.       Die neue Verbindung kristallisiert aus       Eisessig    in feinen Nadeln vom F. 227     bie     229   C.



  Process for the preparation of a highly stable 2,3-gynaphthoic acid arylide. It has been found that the condensation of 2,3-ogynaphthoic acid with 2-amino-3-alkogydiphenylenogyden or its substitute products leads to 2,3-ogynaphthoic acid arylides, which are notable for use as primers in ice dyeing.

   In an alkaline solution they show a very high substantivity compared to vegetable fibers, so that the primer baths are practically largely exhausted.

   Such cooking substance primers are already from German patents No. 556477 and. 572473 has become known, but the arylides obtainable by the present process are distinguished over these known primers by a much better solubility.

    In particular, they do not tend to hydrolysis, which in the case of the previously known boiling substances 2,3-Ogynaphthoesäurearyliden by using a lot of sodium hydroxide to dissolve and long standing .der solution with formaldehyde could be prevented to some extent. Due to their simpler handling, the dye intermediates obtainable according to the present process represent an essential area of technology.



  The subject of the present patent is a process for the production of a highly substantive 2,3-ogynaphthoic acid arylide, which is characterized in that 2,3-ogynaphthoic acid is condensed with 2-amino-3-methogyydiphenylenogyd. <I> example:

  98 parts by weight of 2,3-ogynaphthoic acid are mixed with 108 parts by weight of 2-amino-3-methogydiphenylenogyd from F.92-93'C, which can be obtained, for example, by nitrating 3-methogydiphenylenogyd and the nitro compound obtained reduced to the corresponding amino compound, and <B> 1000 </B> parts by weight of chlorobenzene heated to <B> 80 ° C with stirring.

   30 parts by weight of phosphorus trichloride are slowly added dropwise at this temperature and the mixture is then heated to the boil for several hours. The separated phosphoric acid is separated in a hot state and the chlorobenzene solution is allowed to cool, the condensation product crystallizing out almost completely.

    The 2- (2 ', 3'-Oxyna.phthoylamino) -3-methoxydiphenylene oxide obtained can be used with considerably less sodium hydroxide solution and formaldehyde to produce a stable primer solution than, for example, 4- (2', 3'-Oxyna. phthoylamino) diphenyl. The new compound crystallizes from glacial acetic acid in fine needles from F. 227 to 229 C.
