Description

  

      Zusatzpatent    zum Hauptpatent Nr. 278943.    Verfahren zur Herstellung eines     Indolyl-diphenvlmethanfarbstoffes.       Gegenstand des vorliegenden Zusatzpaten  tes ist ein Verfahren zur Herstellung eines       Indolyl-diphenylmethanfarbstoffes,    welches  dadurch gekennzeichnet ist,     dass    man     4,4'-Di-          chlorbenzophenon-3,3'-disulfosäure    mit     1,4,6-          Trimethyl-2-chlorphenylindol    in etwa mole  kularem     Verhältnis    kondensiert und das erhal  tene Kondensationsprodukt mit einem Über  schuss von     p-Aminodiphenyläther    umsetzt.  



  <I>Beispiel:</I>  35 Gewichtsteile     4,4'-dichlorbenzophenon-          3,3'-disulfosaures    Natrium werden mit 14,5  Gewichtsteilen     1,4,6-Trimethyl-2-chlorphenyl-          indol    in 100 Gewichtsteilen Eisessig bei Gegen  wart von Chlorzink 20 Stunden bei 100  C  kondensiert. Das rote Zwischenprodukt wird  durch Eingiessen in Wasser isoliert und mit  100 Gewichtsteilen     p-Aminodiphenyläther     5 Stunden bei l00  C verschmolzen.

   Die     Farb-          stoffschmelze    wird zur Entfernung des über  schüssigen     p-Aminodiphenyläthers    mit Salz  säure     ausgerührt    und der gebildete Farbstoff    mittels     Natriumcarbonat    gelöst und mit Koch  salz     ausgesalzen.     



  Das so erhaltene Produkt stellt ein violett  glänzendes Pulver dar, das Wolle und Seide  in blauen Tönen färbt, die sich durch     eine,     gute Lichtechtheit und sehr ,gute     Schweiss-          und        Seewasserechtheiten    auszeichnen.



      Additional patent to main patent No. 278943. Process for the production of an indolyl-diphenylmethane dye. The subject of the present additional patent is a process for the production of an indolyl-diphenylmethane dye, which is characterized in that 4,4'-dichlorobenzophenone-3,3'-disulfonic acid with 1,4,6-trimethyl-2-chlorophenylindole in about a molecular ratio condensed and the condensation product obtained is reacted with an excess of p-aminodiphenyl ether.



  <I> Example: </I> 35 parts by weight of 4,4'-dichlorobenzophenone-3,3'-disulfonic acid sodium are mixed with 14.5 parts by weight of 1,4,6-trimethyl-2-chlorophenyl indole in 100 parts by weight of glacial acetic acid at counter was condensed by zinc chloride for 20 hours at 100 C. The red intermediate is isolated by pouring into water and fused with 100 parts by weight of p-aminodiphenyl ether at 100 ° C. for 5 hours.

   To remove the excess p-aminodiphenyl ether, the molten dye is stirred with hydrochloric acid and the dye formed is dissolved using sodium carbonate and salted out with sodium chloride.



  The product obtained in this way is a shimmering violet powder that dyes wool and silk in blue tones, which are characterized by good lightfastness and very, good sweat and sea water fastnesses.
