Description

  

  Verfahren zur Darstellung eines sauren     Wollfarbstoffes    der     Antbrachinonreihe.       Nach der deutschen     Patentschrift    414865  erhält man     Wollfarbstoffe    durch     Sulfieren     von     Amino-    oder     Alkylaminodianthrachino-          nylaminen    mittelst     Oleum    bei An- oder<B>Ab-</B>  wesenheit von Borsäure.  



  Es wurde nun gefunden,     dass    die     Sul-          fierung    dieser     Dianthrachirionylaminderivate     mit     borsäurehaltigem        Oleum    wesentlich ra  scher erfolgt und zu leichter löslichen, wahr  scheinlich höher     sulfierten    Produkten führt,  welche für     Färberzwecke    von besonderem  Wert sind, wenn man sie bei Gegenwart von  Quecksilber oder dessen Verbindungen wie  Oxyde oder Salze, vorzugsweise bei Tempe  raturen zwischen ungefähr 120-150<B>0</B> aus  führt.  



  Es war nicht vorauszusehen,     dass    das  Quecksilber oder seine Salze oder Oxyde  unter diesen Bedingungen den Eintritt von       Suliogruppen    erleichtern würde, ohne die  gleichzeitige Bildung von     Oxydationsprodtik-          ten        züi    begünstigen, wie dies bei Abwesen-         heit    von Borsäure der Fall ist (siehe zum  Beispiel<B>D.</B> R. P.<B>472356,</B> Beispiel<B>3).</B>  



  Gegenstand vorliegenden Patentes ist ein  Verfahren zur Darstellung eines sauren Woll  farbstoffes der     Anthrachinonreihe,    dadurch  gekennzeichnet,     dass    man     4..4'-Diamino-1.1'-          dianthrachinonylamin    mit     Oleum    bei Gegen  wart von Borsäure und, Quecksilber oder  dessen Verbindungen, wie Salze oder Oxyde,  auf Temperaturen zwischen 120 und<B>150 0<I>C</I></B>  erhitzt.  



  <I>Beispiel:</I>  <B>10</B>     Gewiebtsteile        4.4'-Diai,.üino-1.1'-diaii-          thrachinonylamin    werden unter Rühren in       1510    Gewichtsteilen     Oleum    von<B>27</B>     "/o        SU3,     in dem zuvor 4 Teile Borsäure aufgelöst und  0,2 Teile     HgO    suspendiert waren, gelöst und  dann auf 135-140<B>0</B> zirka<B>3</B> Stunden erhitzt.  Die Schmelze wird nach dem Abkühlen in  <B>800</B> Teile Wasser eingerührt, das mit     #venig     schwefliger Säure versetzt war, sodann mit  <B>600</B> Teilen gesättigter     Kochsalzlösung    auf-      gekocht.

   Der abgeschiedene Farbstoff wird       abfiltriert    und mit verdünnter Kochsalzlösung  neutral gewaschen.  



  Das Produkt ist ein     blaugratie#3    Pulver,  das sich in Wasser     grünstichig    blaugrau, in  konzentrierter Schwefelsäure blaugrau, in     Bor-          Schwefelsäure        schmutzig-grün    löst. Es färbt       ungebeizte    Wolle aus saurem Bade in kräf  tigen blaugrauen Tönen von hervorragenden  Echtheitseigenschaften.



  Process for the preparation of an acidic wool dye of the antbrachinone series. According to German patent specification 414865, wool dyes are obtained by sulphonating amino or alkylaminodianthraquinonylamines by means of oleum in the presence or absence of boric acid.



  It has now been found that the sulphation of these dianthrachirionylamine derivatives with boric acid-containing oleum takes place much more rapidly and leads to more soluble, probably more sulphonated products which are of particular value for dyeing purposes if they are used in the presence of mercury or its compounds such as Oxides or salts, preferably at temperatures between about 120-150 <B> 0 </B> from.



  It could not be foreseen that mercury or its salts or oxides would facilitate the entry of sulio groups under these conditions without promoting the simultaneous formation of oxidation products, as is the case in the absence of boric acid (see for example < B> D. </B> RP <B> 472356, </B> Example <B> 3). </B>



  The present patent is a process for the preparation of an acidic wool dye of the anthraquinone series, characterized in that 4..4'-diamino-1.1'-dianthraquinonylamine with oleum in the presence of boric acid and mercury or its compounds, such as salts or oxides , heated to temperatures between 120 and <B> 150 0 <I> C </I> </B>.



  <I> Example: </I> <B> 10 </B> parts by weight of 4.4'-diai, .üino-1.1'-diaiithrachinonylamine are mixed with stirring in 1510 parts by weight of oleum of <B> 27 </B> "/ o SU3, in which 4 parts of boric acid were previously dissolved and 0.2 parts of HgO were suspended, dissolved and then heated to 135-140 <B> 0 </B> hours for about <B> 3 </B> hours After cooling, it was stirred into 800 parts of water to which slightly sulphurous acid had been added, then boiled up with 600 parts of saturated sodium chloride solution.

   The deposited dye is filtered off and washed neutral with dilute sodium chloride solution.



  The product is a blue-gray # 3 powder that dissolves in water with a greenish blue-gray, in concentrated sulfuric acid blue-gray, in boron-sulfuric acid a dirty green. It dyes unstained wool from acid baths in strong blue-gray tones with excellent fastness properties.
