Description

  

      Verfahren    zur Herstellung eines     Farbstoffes        zier        Trinapht@-In@ethanreihe.       Es wurde gefunden, dass durch Behandeln  von     1-Naplrtol-2-ear-borssiiure    mit     Tetralralogen-          nrethan    in Gegenwart eines säurebindenden  Mittels und vorteilhaft in     Gegenwart    eines  Katalysators ein neuer Farbstoff erhalten  wird.

   Dieser bildet, in Form seiner     Farb-          säure,    ein rotbraunes Pulver mit metallischem  Glanz, welches     irr    Wasser schwerlöslich ist,  sich dagegen mit blauer Farbe in Natron  lauge,     Sodaliisurng    sind     cottc.        8chwefelsiittre     löst..

   Auf Wolle     gefärbt    und     naehclrromiert     erzeugt er     reisblaue    Nuancen von     hervor-          ragender        Walk-    und     Pottingechtlteit.       <I>Beispiel 1:</I>  188 Teile     1-Naplttol-2-carbortsi"irrre    werdest  bei 65 o in     einem        Gemisch    aus 525 Teilen  Natronlauge     :e    30      ;

  'o    und 150 'feilest Wasser  gelöst..     Elierauf    gibt man 34 Teile,     T'etra-          chlorkohlenstoff    und 0,2 Teile Kupferpulver  hinzu. blau rührt so lange bei 65      ,    bis die  rasch einsetzende     Farbstoffbildung    beendet  ist, was 6-7 Stunden erfordert.

      Nach     denn        Abstumpfen    eines entsprechen  den Teils des Alkalis kann der     Farbstoff    als       Di-    oder     Tritsatriunnsalz        ausgesalzen    oder       durch        Unnsetzen    mit einem     Erdalkali-    oder  einem     -lagnesittmsalz    als     schwurlösliches    Erd  alkali- oder     liagrtesiunrsalz    isoliert werden.

    <I>Beispiel 2</I>  188 Teile 1-N     aphtol-2-earbonsäure        werden     in 1000     Teilern        Alkohol    unter Zusatz von  130 Teilen 30     ",'oiger    Natronlauge     gelöst.    Es  werden     55    Teile     Tetrachlorkohlenstoff    zuge  fügt und das     (-franze    bei     gewöhnlicher    Tempe  ratur     mittelst    eines     kupfernen        Rührurs        durc.h-          gerülrrt,

      bis     keine        Farbstoffzunahme    mehr zu  erkennen ist. Der als     Na-Salz    kristallinisch  abgeschiedene Farbstoff wird     abfiltriert    und  getrocknet.  



        'endet        man    anstatt     Tetrachlorrnetlnan          Tetrabrommethan    an, so bildet sich derselbe  h     arbstolf.  



      Process for the production of a dye zier Trinapht @ -In @ ethane series. It has been found that treating 1-napol-2-ear-boric acid with tetralralogen nrethane in the presence of an acid-binding agent and advantageously in the presence of a catalyst gives a new dye.

   This forms, in the form of its coloring acid, a red-brown powder with a metallic sheen, which is sparingly soluble in water, but turns blue in caustic soda. 8sulfur acid dissolves ..

   Dyed on wool and chromated, it creates rice-blue nuances of excellent mill and potting fastness. <I> Example 1: </I> 188 parts of 1-Naplttol-2-carbortsi "errre will be at 65 o in a mixture of 525 parts of sodium hydroxide solution: e 30;

  '0 and 150' are dissolved in water. Elierauf is added 34 parts of carbon tetra-chloride and 0.2 part of copper powder. blue stirs at 65 until the rapid onset of dye formation has ended, which takes 6-7 hours.

      After a corresponding part of the alkali has been dulled, the dye can be salted out as di- or tritatrium salt or isolated as a sweat-soluble alkaline earth or liagrtesiunr salt by unsetting with an alkaline earth or magnesium salt.

    <I> Example 2 </I> 188 parts of 1-naphtol-2-carboxylic acid are dissolved in 1000 parts of alcohol with the addition of 130 parts of 30 "oiger sodium hydroxide solution. 55 parts of carbon tetrachloride are added and the (-franze ordinary temperature by means of a copper stirrer.

      until no more dye increase can be seen. The dyestuff, which is deposited in crystalline form as the sodium salt, is filtered off and dried.



        If you end up using tetrabromomethane instead of tetrachloride, the same hardness is formed.
