  Verfahren zur Herstellung von     Chlorterephthaloyl-1-(4'-nitranilid)-4-chlorid.            Gegenstand,des    vorliegenden     Zusatzpaten-          tes    ist ein     Verfahren    zur     Herstellung    von       Chlorterephthaloyl-l-(4'-nitranilid)-4-chlorid,          welches        idaadurch    gekennzeichnet ist, dass man  auf ein     Mol        Chlorteiephthaloylchlorid    in     Ge-          genwart    von organischen     Lösungsmitteln,

      .die  nicht     mit    den     Säurehalogenidgruppen    reagie  ren,     ein.        Mol        4,Nitranilin        in    Form seines       mineralsauren        Salzes        einwirken        lässt.     



       Die    so erhaltene,     bisher    nicht     bekannte          Verbindung    soll     als        Zwischenprodukt    für die  Herstellung von     Farbstoffen.,        pharmazeuti-          schen        Produkten    und     Textilhilfsmitbeln    Ver  wendung finden.  



       Beispiel:     1'30     Gewichtsteile        Chlorterephthaloyl-          c        hloric   <B>1</B>     werden,        in.        600        Volumteilen        Aceton     gelöst, und     bei   <B>50-601'</B> C werden.

   87 Ge  wichtsteile     salzsaures        4-Nitranilin    eingetra  gen, worauf bis zur beginnenden     Bildung    von       Chlorterephfihaloyl-di-(4-nitranilid)    zum Sie  den erhitzt     wird.    Hierauf wird     sofort        filtriert            und        durch        starkes    Abkühlen das     Chlortereph-          thaloyl-1-(4'-nitranilid)-4-ohlorid    abgeschie  den.

   Das     abgesaugte    und mit     kaltem        Aceton          gewaschene        Produkt        wird    im Vakuum bei       Zimmerbemperatur    getrocknet. Durch Ein  engen der Mutterlauge und     anschliessendes          Abkühlen    werden weitere Mengen der Ver  bindung     erhalten.     



  An     Stelle    von     Aceton    als     Lösungemitbel     können andere     Betone,    wie     Methyläthy        lketon     oder     Diäthylketon,        sowie    Kohlen     wasserstoffe,     wie Benzol und     Xylol,        allein    oder in Mi  schung mit den     bereits        erwähnten        Ketonen,     ferner auch     Dioxan    verwendet     werden..     



  Die     erhaltene,        bisher    nicht     bekannte    Ver  bindung     bildet        farblose        Kristalle,    die bei 94  bis 9'5   C     schmelzen.  



  Process for the preparation of chloroterephthaloyl-1- (4'-nitranilide) -4-chloride. The subject of the present additional patent is a process for the production of chloroterephthaloyl-1- (4'-nitranilide) -4-chloride, which is characterized in that one mole of chloroterephthaloyl chloride in the presence of organic solvents,

      .which do not react with the acid halide groups. Mol 4, nitroaniline in the form of its mineral acid salt.



       The previously unknown compound obtained in this way is intended to be used as an intermediate for the production of dyes, pharmaceutical products and textile auxiliaries.



       Example: 1'30 parts by weight of chloroterephthaloyl-chloric <B> 1 </B> are dissolved in 600 parts by volume of acetone and at <B> 50-601 '</B> C.

   Enter 87 parts by weight of hydrochloric acid 4-nitroaniline, after which it is heated to you until chloroterephihaloyl-di- (4-nitranilide) begins to form. It is then filtered immediately and the chloroterephthaloyl-1- (4'-nitranilide) -4-chloride is deposited by vigorous cooling.

   The product which has been filtered off with suction and washed with cold acetone is dried in vacuo at room temperature. By narrowing the mother liquor and then cooling it, further amounts of the compound are obtained.



  Instead of acetone as a solution agent, other concretes such as methyl ethyl ketone or diethyl ketone, and hydrocarbons such as benzene and xylene, alone or in admixture with the ketones already mentioned, and also dioxane can be used.



  The previously unknown compound obtained forms colorless crystals that melt at 94 to 9'5 ° C.
