Description

  

  Verfahren zur Darstellung eines neuen     Thiophenolderivates.       Es wurde gefunden, dass man ein neues       Thioderivat    des Phenols erhalten kann, wenn  man Phenol mit     Antimonpentasulfid    in Ge  genwart von     Calciumhydroxyd    und Schwefel  erhitzt und das erhaltene     Calciumsalz    des       Thiophenols    mit Natriumkarbonat behandelt,  vom gebildeten     Calciumkarbonat        abfiltriert     und das erhaltene     Natriumsalz    des     antimon-          haltigen        Thiophenols    durch Eindampfen iso  liert.  



  <I>Beispiel:</I>  45 Teile Phenol, 40 Teile     Calciumhydro-          xyd,    40 Teile Schwefel und 50 Teile Wasser  werden 30 Stunden lang am     Rückflusskühler     gekocht; nach dieser Zeit werden der     dick-          flessigen    Schmelze 20 Teile     Antimonpenta-          sulfid    zugesetzt und weitere 24 Stunden er  hitzt. Hierauf wird die Masse mit Wasser  verdünnt, mit 50 Teilen Soda versetzt und       abfiltriert.    Man erhält eine hellbraune Lösung,  welche zur Trockne eingedampft wird.  



  Das erhaltene     antimonhaltige    Produkt ist  in Wasser und Äthylalkohol mit braungelber    Farbe leicht löslich; in Aceton ist es schwer  löslich. Auf Zusatz von verdünnten Mineral  und organischen Säuren zu einer verdünnten  Lösung des Produktes werden gelbe Nieder  schläge erhalten; auf Zusatz von     Ferrichlorid     wird ein grauschwarzer Niederschlag erhalten.  Das Produkt liefert mit basischen     Farbstoffen     klare, unlösliche Lacke. Es     besitzt    ferner aus  gezeichnete beizende Eigenschaften. Die da  mit behandelten     Fasern    besitzen eine ausge  zeichnete Lichtechtheit.



  Process for the preparation of a new thiophenol derivative. It has been found that a new thio derivative of phenol can be obtained if phenol is heated with antimony pentasulfide in the presence of calcium hydroxide and sulfur and the calcium salt of thiophenol obtained is treated with sodium carbonate, the calcium carbonate formed is filtered off and the sodium salt of the antimony-containing thiophenol obtained is filtered off isolated by evaporation.



  <I> Example: </I> 45 parts of phenol, 40 parts of calcium hydroxide, 40 parts of sulfur and 50 parts of water are boiled for 30 hours in a reflux condenser; After this time, 20 parts of antimony pentasulfide are added to the viscous melt and it is heated for a further 24 hours. The mass is then diluted with water, mixed with 50 parts of soda and filtered off. A light brown solution is obtained which is evaporated to dryness.



  The product containing antimony is easily soluble in water and ethyl alcohol with a brownish-yellow color; it is sparingly soluble in acetone. Yellow precipitates are obtained on addition of dilute mineral and organic acids to a dilute solution of the product; on addition of ferric chloride, a gray-black precipitate is obtained. With basic dyes, the product provides clear, insoluble paints. It also has excellent caustic properties. The fibers treated there with have excellent lightfastness.
