Description
Verfahren zur Herstellung eines Kondensationsproduktes. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Konden- sationsprocluktes der Formel
EMI0001.0003
dadurch gekennzeichnet, da.ss man ein 3-Tri- fluormethyl -4- chlor- 6 -sulfo-phenyl-1-0-aryl- urethan in Gegenwart von Wasser mit 2,4' hichlor-4-amino-diphenyl-thioäther umsetzt.
Das neue Kondensationsprodukt bildet ein helles, in heissem Wasser klar lösliches Kri stallpulver, das als Mottensehut.zmittel verwen det werden kann.
<I>Beispiel:</I> Zu einer wässrigen Emulsion von 20 Ge wichtsteilen des 3-Trifhtormethyl-4-chlor-6- sulfo-phenyl-1-0-aryl-urethans gibt man die berechnete Menge 2,4'-Dichlor-4-amino-diphe- nyl-thioäther und erwärmt einige Stunden im siedenden Wasserbad. Der Kolbeninhalt wird mit Kochsalz gesättigt. Hierbei scheidet sieh ein Öl aus, das beim Stehen über Nacht fest wird. Das Kondensationsprodukt wird in Wasser von 80 bis 90 gelöst, mit wenig Tier kohle versetzt und heiss filtriert. Nach Zugabe von gesättigter Kochsalzlösung scheidet sich das Kondensationsprodukt in guter Reinheit und Ausbeute aus.
Das neue Kondensationsprodukt stellt nach dem Trocknen und Mahlen ein helles, in hei ssem Wasser klar lösliches Pulver dar.
Process for the production of a condensation product. The subject of the present patent is a process for the production of a condensation product of the formula
EMI0001.0003
characterized in that a 3-trifluoromethyl -4-chloro-6-sulfo-phenyl-1-0-aryl urethane is reacted in the presence of water with 2,4 'dichloro-4-aminodiphenyl thioether .
The new condensation product forms a pale crystal powder which is clearly soluble in hot water and which can be used as a moth hat.
<I> Example: </I> The calculated amount of 2,4'-dichloro is added to an aqueous emulsion of 20 parts by weight of 3-trifhtomethyl-4-chloro-6-sulfo-phenyl-1-0-aryl-urethane -4-amino-diphenyl-thioether and heated for a few hours in a boiling water bath. The contents of the flask are saturated with table salt. Here you see an oil that solidifies when standing overnight. The condensation product is dissolved in water from 80 to 90, mixed with a little animal charcoal and filtered hot. After adding saturated sodium chloride solution, the condensation product separates out in good purity and yield.
After drying and grinding, the new condensation product is a pale powder that is clearly soluble in hot water.
