Description

  

  Verfahren zur Herstellung eines neuen Kondensationsproduktes.    Es wurde gefunden, dass man ein neues  Kondensationsprodukt erhält, wenn man  1     Mol        1-Phenyl-3-methyl-5-pyrazolon-4'-car-          bonsäure    auf 1     Mol    der     Dehydrothiotoluidin-          monosulfonsäure,    die erhältlich ist durch Be-  
EMI0001.0007     
    entspricht, stellt ein helles Pulver dar, das  zur Herstellung von Farbstoffen verwendet  wird.  



  <I>Beispiel:</I>  21,8 Teile     1-Phenyl-3-methyl-5-pyrazolon-          4'-carbonsäure    und 32 Teile     Dehydrothio-          toluidinmonosulfonsäure,    erhalten durch     Sul-          sieren    des     Dehydrothiotoluidins    mit Schwe-    handeln von     Dehydrothiotoluidin    mit     Schwe-          felsäuremonohydrat,        in    Gegenwart     eines          Phosphorchlorides    und eines Verdünnungs  mittels einwirken     läBt.     



  Das neue     Kondensationsprodukt,    das sehr  wahrscheinlich der Formel         felsäuremonohydrat,    werden in die 10fache  Menge eines Gemisches     aus        Pyridin    und       Dimethylanilin    eingetragen und bei 120    6 Teile     Phosphortrichlorid    zugegeben. Man  erhitzt noch 6 Stunden und nach Zugabe von  27 Teilen Soda wird mit Wasserdampf de  stilliert.     Hierauf    wird mit etwas Natrium  karbonat deutlich alkalisch gestellt und fil-      friert. Aus dem Filtrat     wird    durch Aus  säuren das neue Kondensationsprodukt er  halten. Es wird durch     Umlösen    seiner Al  kalisalze gereinigt.



  Process for the production of a new condensation product. It has been found that a new condensation product is obtained if 1 mole of 1-phenyl-3-methyl-5-pyrazolone-4'-carboxylic acid is added to 1 mole of the dehydrothiotoluidine monosulfonic acid, which is obtainable by loading
EMI0001.0007
    corresponds to, represents a light-colored powder that is used in the manufacture of dyes.



  <I> Example: </I> 21.8 parts of 1-phenyl-3-methyl-5-pyrazolone-4'-carboxylic acid and 32 parts of dehydrothiotoluidine monosulfonic acid, obtained by sulfurizing the dehydrothiotoluidine with sulfurizing of dehydrothiotoluidine Sulfuric acid monohydrate, in the presence of a phosphorus chloride and a diluent.



  The new condensation product, which is very likely of the formula felic acid monohydrate, is added to 10 times the amount of a mixture of pyridine and dimethylaniline and 6 parts of phosphorus trichloride are added at 120. The mixture is heated for a further 6 hours and after addition of 27 parts of soda is distilled with steam. Then it is made clearly alkaline with a little sodium carbonate and then filtered. The new condensation product is obtained from the filtrate by means of acids. It is purified by dissolving its alkali salts.
