Description

  

  Verfahren zur Herstellung eines unlöslichen Farbstoffes.    Es wurde     gef-unden,        dass    man zu einem  wertvollen unlöslichen Farbstoff gelangt,  wenn man     1-Plienyl-3-metliyl-5-pyrazolon     mit dem     Azomethin    der Formel  
EMI0001.0005     
    unter Abspalten von     1-Aminobenzol-3-sul-          fonsäure    kondensiert.  



  Das so erhaltene Kondensationsprodukt ist  ein rotes Pulver, das sich in organischen Lö  sungsmitteln, wie Aceton, Essigester, mit  gelbroter Farbe löst und das, in geeignete  Verteilung gebracht,     Acetatkunstseide    in ech  ten rotgelben Tönen färbt.  



  <I>Beispiel:</I>  In eine Lösung von<B>38,3</B> Teilen des     Azo-          methins    der Formel  
EMI0001.0011     
    in<B>300</B> Teilen einer     10%igen        Natriumearbo-          natlösung    giesst man unter Rühren eine Sus-         pension    von 17,4 Teilen     1-Phenyl-3-methyl-          5-pyrazolon    in<B>300</B> Teilen Wasser.     Nael     zirka 15stündigem Rühren ist das neue Kon  densationsprodukt gebildet und als rotes Pul  ver ausgefallen. Es wird     abfiltriert    und ge  trocknet.



  Process for the preparation of an insoluble dye. It has been found that a valuable insoluble dye is obtained by mixing 1-plienyl-3-methyl-5-pyrazolone with the azomethine of the formula
EMI0001.0005
    condensed with elimination of 1-aminobenzene-3-sulphonic acid.



  The condensation product obtained in this way is a red powder which dissolves in organic solvents such as acetone, ethyl acetate, with a yellow-red color and which, when appropriately distributed, dyes acetate rayon in real red-yellow tones.



  <I> Example: </I> In a solution of <B> 38.3 </B> parts of the azomethine of the formula
EMI0001.0011
    A suspension of 17.4 parts of 1-phenyl-3-methyl-5-pyrazolone in 300 is poured into 300 parts of a 10% sodium carbonate solution, while stirring Share water. After stirring for about 15 hours, the new condensation product has formed and precipitated as a red powder. It is filtered off and dried ge.
