Description

  

  Verfahren zur Darstellung eines     ehromierbaren    Farbstoffes der     Triarylmethanreihe.            Gegenstand    dieses     Zusatzpatentes        isst        ein     Verfahren zur     Darstellung    eines     chromier-          baren        Farbstoffes    der     Triarylmethanreihe,     welches dadurch     ,gekennzeichnet    ist,

   dass     man          m-Piperidyl-phenol    mit     5-Ogytrimellithsäure-          anhydrid        kondensiert.       <I>Beispiel:</I>       ss5        ,Gewichtsteile        m-Piperidyl-phenol    (aus       Resorcin    und     Piperidin    bei<B>150'</B> C erhalten)       werden    mit 84     Gewichtsteilen        @5-Ogytrimel-          lithsäureanhydrid    bei<B>170-180'</B> C drei     ,

  Process for the preparation of an honorable dye of the triarylmethane series. The subject of this additional patent is a process for the preparation of a chromable dye of the triarylmethane series, which is characterized by

   that m-piperidyl-phenol is condensed with 5-ogytrimellitic anhydride. <I> Example: </I> ss5, parts by weight of m-piperidyl-phenol (obtained from resorcinol and piperidine at <B> 150 '</B> C) are combined with 84 parts by weight of 5-ogytrimellitic anhydride at <B> 170 -180 '</B> C three,

  Fused for hours with stirring. The cooled and pulverized melt is stirred with 500 parts by weight of concentrated hydrochloric acid until the dye is dissolved, the solution is suctioned off from the excess 5-ogytrimellitic acid and by-products and the dye is precipitated from the hydrochloric acid solution with 4-5 times the volume of water.

   The dye has the following constitution:
EMI0001.0043
    Fr dyes wool from acid baths: in fluorescent. tend to violet-red tones, which become a little darker when chroming and then show very good honesty.
