Description

  

  Zusatzpatent zum Hauptpatent Nr. 143025.    Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen  wertvollen Farbstoff erhält, wenn man 2     Mol          Deliydrothio-p-toluidinmonosulfosäure    mit.  einem     Mol        4.4'Dinitrostilben-2.2'-disulfo-          säure        unter    Druck kondensiert.  



  Der neue     Farbstoff    stellt getrocknet ein  Totoranges Pulver dar, welches sich in Was  ser und verdünnten Alkalien mit orangegelber,  in konzentrierter Schwefelsäure mit violetter  Farbe löst und Baumwolle in sehr licht- und       alkaliechten    orangegelben Tönen anfärbt.  



  <I>Beispiel:</I>  Man beschickt einen     Rührautoklaven    mit  einem Gemisch     vors    64 Teilen     Dehydrothio-          p-toluidinmonosulfosäLire,    43 Teilen p .     p'-          dinitrostilben    - o. o'-     disulfosaurem    Natrium,  1000 Teilen Wasser und 156 Teilen Natron  lauge von 36      B6.    Man erwärmt auf 120    und kondensiert 6 Stunden bei dieser Tem-         peratur.    Nach dem     Eikalter)    wird der Farb  stoff vollends     ausgesalzen,        abgenutseht,    ge  presst und getrocknet.



  Additional patent to main patent No. 143025. Process for the production of a new dye. It has been found that a new valuable dye is obtained if 2 moles of deliydrothio-p-toluidine monosulfonic acid are used. one mole of 4.4'Dinitrostilben-2.2'-disulfonic acid condensed under pressure.



  When dried, the new dye is a Totorange powder that dissolves in water and dilute alkalis with an orange-yellow color, in concentrated sulfuric acid with a violet color and dyes cotton in very light and alkali-like orange-yellow tones.



  <I> Example: </I> A stirred autoclave is charged with a mixture of 64 parts of dehydrothio-p-toluidine monosulfosallire, 43 parts of p. p'- dinitrostilben - o. o'- disulfosaurem sodium, 1000 parts of water and 156 parts of sodium hydroxide solution of 36 B6. The mixture is heated to 120 and condensed for 6 hours at this temperature. After the ice cold), the dye is completely salted out, grooved, pressed and dried.
