Description

  

  Verfahren zur Herstellung von     2-Methylaminophenol.       Gegenstand     des    vorliegenden Patentes     ist     ein Verfahren zur     Herstellung    von 2-     Methyl-          aminophenol,    welches dadurch     gekennzeich-          net    ist,     dass    man     o-Propionyl-methyl-amino-          phenol    mit starken Mineralsäuren verseift.  



  Gegenüber den bisher bekannten Verfah  ren zur Herstellung dieses Stoffes ist das vor  liegende Verfahren leichter durchführbar,  und ergibt es bessere     Ausbeuten.     



  Das erhaltene     2-Methyl-aminophenol    kann  insbesondere als     Entwzeklersubstanz    verwen  det werden.    <I>Beispiel:</I>       o-Propionyl-methyl-aminophenol    (F. P.  



  151  )     wird    mit     2'0        %        iger    Salzsäure zum     2-          Methyl-aminophenol    verseift.



  Process for the preparation of 2-methylaminophenol. The subject of the present patent is a process for the preparation of 2-methylaminophenol, which is characterized in that o-propionyl-methylamino-phenol is saponified with strong mineral acids.



  Compared to the previously known procedural Ren for the production of this substance, the present process is easier to carry out, and it gives better yields.



  The 2-methyl-aminophenol obtained can in particular be used as a desiccant substance. <I> Example: </I> o-Propionyl-methyl-aminophenol (F. P.



  151) is saponified with 2'0% hydrochloric acid to form 2-methyl-aminophenol.
