Description

  

      Verfahren    zur Herstellung eines     chromierbaren        Farbstoffes    der     Triarylmethanreihe.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Herstellung     eines        chromier-          baren    Farbstoffes der     Triarylmethanreihe,     welches dadurch     gekennzeichnet    ist, dass man       1-(4'-Diäthylamino-2'-ogybenzoyl)-o-ogycarb-          ogy-2-benzoesäure,

      die durch Verschmelzen  von 5 -     Ogytrimellitsäureanhydrid    mit     Di-          äthylamino    - m     -phenol    während mehrerer  Stunden bei etwa 120 bis<B>130'</B> C erhältlich  ist,     mit    dem aus     diazotiertem        o-Anisidin    und       Resorcin    erhältlichen     Azofarbstoff    konden  siert.

           Beispiel:       7,4 Gewichtsteile des salzsauren Salzes der       1-(4'-Diäthylamino-2'-ogybenzoyl)-o-ogycarb-          ogy-2-benzoesäure,    die durch Verschmelzen  von 5 -     Ogytrimellitsäureanhydrid    mit     Di-          äthylamino    - m -     phenol    während mehrerer  Stunden bei     etwa    120 bis 130   C erhältlich  ist, und 4,3     Gewichtsteile    des     Azofarbstoffes,

       der durch     Diazotieren    und Kuppeln von o-         Anisidin    auf     Resorcin    erhalten     wurde,    wer  den in 40     Volumteilen    konzentrierter Schwe  felsäure 4 bis 5 Stunden auf<B>90'</B> C erwärmt.  Nach Zugabe von 400 Gewichtsteilen Was  ser und kurzem Erwärmen erhält man     einen     Farbstoff, der, kalt abgesaugt, neutral ge  waschen, in das     Natriumsalz    überführt wird.  Aus saurem Bade gefärbt, erhält man ein  trübes Rot, das     nachchromiert    etwas blauer  und echter wird.



      Process for the preparation of a chromable dye of the triarylmethane series. The subject of this additional patent is a process for the production of a chromable dye of the triarylmethane series, which is characterized in that 1- (4'-diethylamino-2'-ogybenzoyl) -o-ogycarb-ogy-2-benzoic acid,

      which is obtainable by fusing 5 - ogytrimellitic anhydride with diethylamino - m -phenol for several hours at about 120 to 130 ° C, condenses with the azo dye obtainable from diazotized o-anisidine and resorcinol.

           Example: 7.4 parts by weight of the hydrochloric acid salt of 1- (4'-diethylamino-2'-ogybenzoyl) -o-ogycarb-ogy-2-benzoic acid, which is obtained by fusing 5 - ogytrimellitic anhydride with diethylamino - m - phenol during several hours at about 120 to 130 C, and 4.3 parts by weight of the azo dye,

       which was obtained by diazotizing and coupling o-anisidine on resorcinol, who heated the concentrated sulfuric acid in 40 parts by volume to 90 ° C for 4 to 5 hours. After adding 400 parts by weight of water and briefly warming up, a dye is obtained which, suctioned off cold, washed neutral ge, is converted into the sodium salt. Dyed from an acidic bath, the result is a cloudy red that, when chromed, becomes a little bluer and more genuine.

<B>PATENTANSPRUCH:</B> Verfahren zur Herstellung eines chromier- baren Farbstoffes der Triarylmethanreihe, dadurch gekennzeichnet, dass man 1-(4'-Di- äthylamino - 2'- ogybenzoyl) - o - ogycarbogy- 2- benzoesäure, <B> PATENT CLAIM: </B> Process for the production of a chromable dye of the triarylmethane series, characterized in that 1- (4'-diethylamino-2'-ogybenzoyl) - o-ogycarbogy-2-benzoic acid, die durch Verschmelzen von 5- Ogytrimellitsäureanhydrid mit Diäthyl- amino-m-phenol während mehrerer Stunden bei etwa 120 bis<B>1300</B> C erhältlich ist, mit dem aus diazotiertem o-Anisidin und Resor- cin erhältlichen Azofarbstoff kondensiert. which is obtainable by fusing 5-ogytrimellitic anhydride with diethylamino-m-phenol for several hours at about 120 to 1300 C, condenses with the azo dye obtainable from diazotized o-anisidine and resorcinol. Der so erhaltene Parbstoff liefert auf Wolle aus saurem Bade rote Töne, die dureh Nachchromieren etwas blauer und in den Echtheitseigenschaften verbessert werden. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man die Kondensation durch Ei rhitzen der lReaktionskomponenten auf 90 C während 4 bis 5 Stunden in kon zentrierter Schwefelsäure bewirkt. The paraffin obtained in this way provides red shades on wool from acid baths, which are somewhat bluer and the fastness properties are improved by subsequent chrome plating. SUBSTANTIAL CLAIM: Process according to patent claim, characterized in that the condensation is brought about by heating the reaction components to 90 C for 4 to 5 hours in concentrated sulfuric acid.
