Description

  

  Verfahren zur Herstellung von     Ter        ephthaloyl-1-(2',4'-dichlor        anilid)-4-chlorid.            Gegenstand    des vorliegenden     Zusatzpaten-          tes    ist ein     Verfahren    zur Herstellung von       Terephthaloyl    - 1 -     (2',4'-        diehloranilid)    - 4     -          chlorid,        welches    dadurch     gekennzeichnet        ist,

            .dass    man auf ein     Mol        Terephthaloylchlorid    in  Gegenwart von organischen     Lösungsmitteln,     ,die nicht mit den     Säurehalogentidgruppen     reagieren,     ein        Mol        2;4-Dichloranilin    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     Textilhilfsmitteln        Ver-          wendung    finden.  



  <I>Beispiel:</I>  112     Gewichtsteile        Terephthaloylohlorid     werden in 600     Volumteil_en    Aceton gelöst,  und bei     5;0--55      C werden 99     Gewichtsteile     Salzsäure     2,4-Dichloranilineingetragen,    wor  auf     bis    zur beginnenden     Bildung    von     Tere-          phthaloyl--di-(2,4-.dichloranilid)    zum Sieden  erhitzt wird..

   Hierauf wird sofort filtriert und    durch     starkes        Abkühlen    das     Temphthaloyl-l-          (2',4'-dichloranilid)--4,1chlorid    abgeschieden.  Das abgesaugte und mit kaltem Aceton     .ge-          waschene        Produkt    wird im Vakuum bei     Zim-          mertemperatur        .getrocknet.    Durch     Einengen     .der     Mutterlauge    und     anschliessendes    Abküh  len werden weitere     Mengen    der Verbindung  erhalten.  



  An     Stelle        von.        Aceton    als     Lösungsmittel     können     andere        getane,    wie     Methyläthylketon     oder     Diäthylketon,    sowie     Kohlenwasserstoffe,     wie Benzol und     Xylol,    allein oder in Mi  schung mit Aden bereits     erwähnten        Betonen,     ferner auch     Dioxan        verwendet    werden.  



  Die erhaltene, bisher nicht bekannte Ver  bindung bildet farblose Kristalle, die bei       1'40      C schmelzen.



  Process for the preparation of Ter ephthaloyl-1- (2 ', 4'-dichloro anilide) -4-chloride. The subject of the present additional patent is a process for the production of terephthaloyl - 1 - (2 ', 4'-diehloranilid) - 4 - chloride, which is characterized by

            .that one mole of terephthaloyl chloride in the presence of organic solvents, which do not react with the acid halide groups, allows one mole of 2,4-dichloroaniline to act in the form of its mineral acid salt.



  The compound obtained in this way and not previously known is intended to be used as an intermediate for the production of dyes, pharmaceutical products and textile auxiliaries.



  <I> Example: </I> 112 parts by weight of terephthaloylochloride are dissolved in 600 parts by volume of acetone, and at 5; 0-55 ° C. 99 parts by weight of hydrochloric acid 2,4-dichloroaniline are introduced, which leads to the formation of terephthaloyl-- di- (2,4-dichloroanilide) is heated to boiling.

   It is then filtered immediately and the temphthaloyl-1- (2 ', 4'-dichloroanilide) -4.1 chloride is deposited by vigorous cooling. The product, which has been suctioned off and washed with cold acetone, is dried in vacuo at room temperature. Concentration of the mother liquor and subsequent cooling give further amounts of the compound.



  Instead of. Acetone as a solvent, other done, such as methyl ethyl ketone or diethyl ketone, and hydrocarbons such as benzene and xylene, alone or mixed with adene already mentioned concretes, also dioxane can be used.



  The compound obtained, previously unknown, forms colorless crystals that melt at 1.40 ° C.
