Description

  

  Verfahren zur Herstellung eines     nichtfärbenden        Thloderivates    des Chlorphenols.    Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Herstellung eines nichtfärben  den     Thioderivates    des Chlorphenols, welches  dadurch gekennzeichnet ist, dass man auf Chlor  phenol eine     Halogenschwefelverbindung    in Ge  genwart einer Zinnverbindung einwirken lässt.  <I>Beispiel:</I>  In 54 Gewichtsteile geschmolzenem Chlor  phenol werden 20 Gewichtsteile     Zinnchlorür     suspendiert.

   Man lässt 70 Gewichtsteile Chlor  schwefel     zutropfen,    rührt in der Wärme (bei  einer Temperatur von etwa     50-100')    noch  einige Zeit nach und gibt langsam 100 Ge  wichtsteile 35     o/oige    Natronlauge zu. Man  kocht nun etwa 25 Stunden unter     Rückfluss,     lässt abkühlen und trennt das ausgeschiedene  Produkt von der überstehenden Flüssigkeit.  Dann löst man es in Wasser und Natron  lauge, filtriert und dampft das Filtrat im  Vakuum zur Trockne. Das so erhaltene  Produkt ist wasserlöslich und     wird    aus dieser  Lösung durch verdünnte Säuren gefällt.

   Es  kann direkt als Beize und     Reservierungsmittel          verwendetwerden.    Das     Reservierungsvermögen       zum Beispiel ist sehr stark und nicht von  der Temperatur des Färbebades abhängig.



  Process for the preparation of a non-coloring chloride derivative of chlorophenol. The subject of this additional patent is a process for the production of a non-coloring thio derivative of chlorophenol, which is characterized in that a halosulfur compound is allowed to act on chlorophenol in the presence of a tin compound. <I> Example: </I> 20 parts by weight of tin chloride are suspended in 54 parts by weight of molten chlorophenol.

   70 parts by weight of chlorine sulfur are added dropwise, the mixture is stirred in the warm (at a temperature of about 50-100 °) for some time and 100 parts by weight of 35% sodium hydroxide solution are slowly added. The mixture is then refluxed for about 25 hours, allowed to cool and the precipitated product is separated from the supernatant liquid. It is then dissolved in water and sodium hydroxide solution, filtered and the filtrate is evaporated to dryness in a vacuum. The product obtained in this way is water-soluble and is precipitated from this solution using dilute acids.

   It can be used directly as a stain and reservation agent. The ability to reserve, for example, is very strong and does not depend on the temperature of the dye bath.

PATENTANSPRUCH: Verfahren zur Herstellung eines nicht färbenden Thioderivates des Chlorphenols, dadurch gekennzeichnet, dass man auf Chlor phenol eine Halogenschwefelverbindung in Ge genwart einer Zinnverbindung einwirken lässt. Das erhaltene Produkt ist in Form seiner Alkalisalze wasserlöslich und wird aus dieser Lösung durch verdünnte Säuren gefällt. Es kann direkt als Beize und Reservierungsmittel verwendet werden. Das Reservierungsvermögen zum Beispiel ist sehr stark und nicht von der Temperatur des Färbebades abhängig. Claim: Process for the production of a non-coloring thio derivative of chlorophenol, characterized in that a halogenated sulfur compound is allowed to act on chlorophenol in the presence of a tin compound. The product obtained is water-soluble in the form of its alkali metal salts and is precipitated from this solution using dilute acids. It can be used directly as a stain and reservation agent. The ability to reserve, for example, is very strong and does not depend on the temperature of the dye bath. UNTERANSPRUCH: Verfahren nach Patentanspruch, dadurch gekennzeichnet, dass man Chlorschwefel zu einer Suspension von Chlorphenol und Zinn- chlorür in der Wärme zutropfen lässt. SUBSTANTIAL CLAIM: Process according to patent claim, characterized in that chlorosulfur is allowed to drop in hot water to a suspension of chlorophenol and tin chlorine.
