Description

  

  Verfahren zur Herstellung eines     stickstoffhaltigen    aromatischen     Aldehyds.       Gegenstand des     vorliegenden    Patentes ist  ein Verfahren zur     I3erstellung    eines stick  stoffhaltigen aromatischen Aldehyds.

   Das  Verfahren     ist    dadurch     gekennzeiohnet,    dass  in-an     N-Chloräthyldiphenylamin,        N-Methyl-          formanilid    und     Phosphoroxychlorid        aufein-          a.nder    einwirken     lä.sst.    Der so     erhältliche          p-Chloräthy        lphenylaminobenzald-ehyd    stellt  ein schwach gefärbtes     @01    dar. Es soll zur  Synthese von Farbstoffen u. a. dienen.  



       Beispiel:     Man versetzt allmählich 53 Gewichtsteile       N-Oxyäthyldiphenylamin    mit 42 Gewichts  teilen     P'hosphoroxychlorid    bei ca.<B>60',</B> er  wärmt     zwen        Stunden    auf 90 bis     1.00;'    und  tropft hierzu     naoh        Abkühlen    bei     etwa    20'       eine        Mischung    von 68 Gewichtsteilen     N-          3Tethylformanilid    und 77     Gewichtsteilen          Phosphoroxychlorid    in 100 Gewichtsteilen  Benzol zu.

   Nach     mehrstündigem    Erwärmen  auf     4.5        bis   <B>50'</B> und Austragen auf Eis     trennt     man die     benzolische.Schicht    ab, wäscht mehr  mals mit     oalz@s!äurohaltigem    Wasser und er-    hält dann ,den     p-Chloräthylphenylaminoben,z-          aldeby    d nach     Abd@estillieren    des Benzols als  schwach     gefärbtes    Öl in     sehr        guter    Aus  beute.



  Process for the preparation of a nitrogen-containing aromatic aldehyde. The subject of the present patent is a process for the production of a nitrogen-containing aromatic aldehyde.

   The process is characterized in that in-an N-chloroethyldiphenylamine, N-methylformanilide and phosphorus oxychloride act on one another. The thus obtainable p-Chloräthy lphenylaminobenzald-ehyd is a weakly colored @ 01. It is said to be used for the synthesis of dyes u. a. serve.



       Example: 53 parts by weight of N-oxyethyldiphenylamine are gradually added to 42 parts by weight of phosphorus oxychloride at about <B> 60 ', </B> it is heated to 90 to 1.00 for two hours;' and after cooling at about 20 ', add a mixture of 68 parts by weight of N-3-ethylformanilide and 77 parts by weight of phosphorus oxychloride in 100 parts by weight of benzene.

   After several hours of warming to 4.5 to 50 'and discharging onto ice, the benzene layer is separated off, washed several times with water containing oaline and then obtained the p-chloroethylphenylamine above, e.g. aldeby d after distilling off the benzene as a weakly colored oil in very good yield.
