Description

  

  Verfahren zur Herstellung eines     stickstoffhaltigen,    aromatischen     Aldebyds.       Gegenstand des vorliegenden Patentes  ist ein Verfahren zur Herstellung eines stick  stoffhaltigen, aromatischen Aldehyds. Das  Verfahren ist dadurch gekennzeichnet, dass  man     N-,Q-Chlorpropyl-N-methyl-anilin,        N-Me-          thylformanilid    und     Phosphoroxychlorid    auf  einander einwirken lädt. Der so erhältliche       @-Chlorpropylmethylaminobenzaldehyd    stellt  ein wenig gefärbtes<B>01</B> dar. Es soll zur  Synthese von     Farbstoffen    u. a. dienen.  



  <I>Beispiel:</I>  Zu 80 Gewichtsteilen     Phosphoroxychlorid     lädt man bei 200 83 Gewichtsteile     N-ss-          Oxypropyl-N-methylanilin    langsam     zutropfen     und erwärmt das Gemisch noch einige Stun  den auf 90-100  . Nach dem Abkühlen auf  20-25   lädt man ein Gemisch von 135 Ge  wichtsteilen     Methylformanilid    und 154 Ge  wichtsteilen     Phosphoroxychlorid        zutropfen,     erwärmt nach einigen Stunden auf     45-500     und trägt auf Eis aus.

   Der entstandene p  ss-Chlorpropylmc     thylaminobenzaldehyd    fällt  dabei als wenig gefärbtes Öl aus und lädt    sich ohne weitere Reinigung zu weiteren  Reaktionen verwenden. Die     Ausbeute    ist gut.



  Process for the production of a nitrogen-containing, aromatic aldebyd. The subject of the present patent is a process for the preparation of a stick-containing aromatic aldehyde. The method is characterized in that N-, Q-chloropropyl-N-methyl-aniline, N-methylformanilide and phosphorus oxychloride are charged to act on one another. The @ -chloropropylmethylaminobenzaldehyde which can be obtained in this way is a slightly colored <B> 01 </B>. It is said to be used for the synthesis of dyes and the like. a. serve.



  <I> Example: </I> 80 parts by weight of phosphorus oxychloride are slowly added dropwise at 200 83 parts by weight of N-ss-oxypropyl-N-methylaniline and the mixture is heated to 90-100 for a few more hours. After cooling to 20-25, a mixture of 135 parts by weight of methylformanilide and 154 parts by weight of phosphorus oxychloride is added dropwise, heated after a few hours to 45-500 and carried out onto ice.

   The resulting pss-chloropropyl methylaminobenzaldehyde precipitates out as an oil of little color and can be used for further reactions without further purification. The yield is good.
