Description

  

  Verfahren zur Herstellung eines wasserlöslichen     Nottenschützmittels.       Gegenstand dieses Patentes ist ein Ver  fahren zur Herstellung eines wasserlöslichen  Mottenschutzmittels. Das Verfahren ist da  durch gekennzeichnet, dass man     2,2'-Dioxy-          3,3',5,5',3",4"-hexachlortriphenylmethan    mit       Benzoesäure-m-sulfosäurehalogenid    in Gegen  wart eines säurebindenden Mittels, wie bei  spielsweise wasserfreien     Pyridins,    umsetzt.  Der     gebildete    neue Ester kann in Form  seines     Natriumsalzes    ausgeschieden werden.

    <I>Beispiel:</I>  Man löst 46 Gewichtsteile     Benzoesäure-m-          sulfochlorid    in 100 Gewichtsteilen wasser  freiem     Pyridin    bei etwa 80  C und gibt nach  und nach unter Rühren 48 Gewichtsteile       hexachlortriphenyl        -          methan    hinzu. Nach ein- bis     zweistündigem     Rühren ist die Reaktion beendet. Nach dem  Verdünnen mit Wasser und Ansäuern kann  der Ester     bezw.    sein     Natriumsalz    durch Aus  salzen mit Kochsalz abgeschieden werden.  



  Behandelt man Wollgewebe z. B. mit 1  des so erhältlichen Esters (bezogen auf das  Warengewicht) nach Art des Färbeprozesses    unter Zusatz von     Essigsäure    und Schwefel  säure eine Stunde bei     Kochtemperatur,    so  erhält die Ware dadurch einen echten  Mottenschutz.  



  Die gleiche Schutzwirkung wird erhalten,  wenn man Mischgewebe, das aus Wolle und       Viskose-Zellwolle    besteht, mit 1 % (bezogen  auf das Warengewicht) obiger Verbindung  in neutraler Flotte eine Stunde bei<B>95'</B> C  unter Zusatz von 10 % Glaubersalz behandelt.



  Process for the production of a water-soluble emergency protective agent. 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'-dioxy-3,3 ', 5,5', 3 ", 4" -hexachlorotriphenylmethane with benzoic acid-m-sulfonic acid halide in the presence of an acid-binding agent, such as anhydrous for example Pyridins. The new ester formed can be excreted in the form of its sodium salt.

    <I> Example: </I> 46 parts by weight of benzoic acid m-sulfochloride are dissolved in 100 parts by weight of anhydrous pyridine at about 80 ° C. and 48 parts by weight of hexachlorotriphenyl methane are gradually added with stirring. After stirring for one to two hours, the reaction has ended. After diluting with water and acidifying the ester can BEZW. its sodium salt can be deposited by salting it out with table salt.



  If you treat woolen fabric z. B. with 1 of the ester obtainable in this way (based on the weight of the goods) according to the type of dyeing process with the addition of acetic acid and sulfuric acid for one hour at the boiling temperature, the goods receive a real moth protection.



  The same protective effect is obtained if mixed fabrics consisting of wool and viscose-cellulose wool are mixed with 1% (based on the weight of the goods) of the above compound in a neutral liquor for one hour at 95 ° C with the addition of 10% % Glauber's salt treated.
