Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 213419.    Verfahren zur Herstellung eines neuen Kondensationsproduktes.    Es wurde gefunden, dass man zu     einem     neuen Kondensationsprodukt gelangt, wenn  man     2,4-Dimethyl-6-chlormethylphenol    mit       Thioharnstoff    umsetzt.  



  Die Umsetzung     wird    zweckmässig in Ge  genwart eines Lösungsmittels, wie Aceton,  vorgenommen.  



  Das neue Kondensationsprodukt stellt eine  schwach gelbgefärbte     Kristallmasse    dar, die  in Wasser leicht löslich ist und deren wässerige  Lösung auf Zusatz von     Natriumcarbonat    einen  unlöslichen Niederschlag abscheidet. Es kann  als     Textilhilfsstoff    verwendet werden.  



  <I>Beispiel:</I>  Man löst 5,1 Gewichtsteile     2,4-Dimethyl-          6-chlormethylphenol,    welches beispielsweise  durch Umsetzen des     o-Mesitylalkohols    mit       Salzsäuregas    in bekannter Weise erhalten  werden kann, in 20     Volumteilen    Aceton. Dazu  werden unter Rühren bei Raumtemperatur  nach und nach 2,7     Gewichtsteile    fein pulve  risierter     Thioharnstoff    gegeben. Das Reaktions  produkt scheidet sich in     Form    von farblosen  Kristallen aus. Nach einstündigem Rühren  bei Raumtemperatur ist die Umsetzung beendet.

      Nach dem<B>Ab</B> filtrieren wird das neue Produkt  als schwach gelbgefärbte     Kristallmasse    er  halten,     die    in Wasser leicht     löslich    ist und  deren wässerige Lösung auf Zusatz von     Na-          triumcarbonat    sofort einen     unlöslichen    Nieder  schlag abscheidet.



  <B> Additional patent </B> to main patent no. 213419. Process for the production of a new condensation product. It has been found that a new condensation product is obtained if 2,4-dimethyl-6-chloromethylphenol is reacted with thiourea.



  The reaction is expediently carried out in the presence of a solvent such as acetone.



  The new condensation product is a pale yellow-colored crystal mass which is easily soluble in water and the aqueous solution of which separates an insoluble precipitate on addition of sodium carbonate. It can be used as a textile auxiliary.



  <I> Example: </I> 5.1 parts by weight of 2,4-dimethyl-6-chloromethylphenol, which can be obtained, for example, by reacting o-mesityl alcohol with hydrochloric acid gas in a known manner, in 20 parts by volume of acetone. To this end, 2.7 parts by weight of finely powdered thiourea are gradually added at room temperature with stirring. The reaction product separates out in the form of colorless crystals. After stirring for one hour at room temperature, the reaction has ended.

      After the <B> Ab </B> filtration, the new product is obtained as a pale yellow-colored crystal mass, which is easily soluble in water and whose aqueous solution immediately separates an insoluble precipitate upon addition of sodium carbonate.
