Description
Verfahren zur Herstellung eines wasserlöslichen Mottenschutzmittels. Gegenstand dieses Patentes ist ein Ver fahren zur Herstellung eines wasserlöslichen Mottenschutzmittels. Das Verfahren ist da durch gekennzeichnet, dass man 2,2'-Diogy- 3,31' - 5,5'-4"-pentachlortriphenylmethan mit Sulfoessigsäurehalogenid in Gegenwart eines säurebindenden Mittels, beispielsweise was serfreien Pyridins, umsetzt. Der gebildete Ester kann in Form seines Natriumsalzes ab geschieden werden.
<I>Beispiel:</I> 35 Teile Sulfoessigsäurechlorid werden in <B>1.00</B> Teilen wasserfreiem Pyridin aufgelöst und dieser Lösung 44 Teile 2,2'-Diogy- 3,3'-5,5'-4"-pentachlortriphenylmethan un ter Rühren anschliessend zugefügt. Die Re aktion ist nach ein- bis zweistündigem Rüh ren bei einer Temperatur von 90 beendet. Nach der Verdünnung mit Wasser und An säuerung scheidet sich der Ester bezw. sein Dinatriumsalz durch Aussälzen mit Koch salz aus.
Wenn man ein Wollgewebe zum Beispiel mit 1 % (berechnet auf das Gewicht des zu behandelnden Materials) des so erhaltenen Esters gemäss dem Färbeprozess unter Hin- zugabe von Essigsäure und Schwefelsäure für eine Stunde beim Siedepunkt behandelt. so ist das Gewebe gegen: Mottenangriff ge schützt.
Die gleiche Schutzwirkung wird erhalten durch Behandlung von Mischgeweben, die aus Wolle und Viskose-Fasern bestehen, für eine Stunde bei einer Temperatur von 95 mit 1 % (berechnet auf das Gewicht des zu behandelnden Materials) der ubengenannten Verbindung in neutralem Bad mit 10 Glaubersalz.
Process for the production of a water-soluble moth repellent. The subject of this patent is a process for the production of a water-soluble moth repellent. The process is characterized in that 2,2'-diogy-3,31 '- 5,5'-4 "-pentachlorotriphenylmethane is reacted with sulfoacetic acid halide in the presence of an acid-binding agent, for example water-free pyridine. The ester formed can be converted into Form of its sodium salt to be divorced.
<I> Example: </I> 35 parts of sulfoacetic acid chloride are dissolved in <B> 1.00 </B> parts of anhydrous pyridine and 44 parts of 2,2'-Diogy-3,3'-5,5'-4 " The reaction is complete after one to two hours of stirring at a temperature of 90. After dilution with water and acidification, the ester or its disodium salt separates out by salting out with sodium chloride.
If, for example, a woolen fabric is treated with 1% (calculated on the weight of the material to be treated) of the ester obtained in this way according to the dyeing process with the addition of acetic acid and sulfuric acid for one hour at the boiling point. so the tissue is protected against: Moth attack.
The same protective effect is obtained by treating mixed fabrics consisting of wool and viscose fibers for one hour at a temperature of 95 with 1% (calculated on the weight of the material to be treated) of the aforementioned compound in a neutral bath with 10 Glauber's salt.
