Description

  

  Verfahren zur Darstellung eines     Harnstoffderivates.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur     Herstellung    eines Harn  stoffderivates der Formel  
EMI0001.0003     
    dadurch gekennzeichnet, dass man     4-Amino-          4'-chlor-1,1'-diphenylsulfid-2-sulfonsäure    mit       Phosgen    umsetzt. Das neue     Harnstoffderivat     bildet als     Natriumsalz    ein helles, gut wasser  lösliches Pulver, das sich zur Verwendung  als Mottenschutzmittel eignet.  



  <I>Beispiel:</I>  20 Teile     4-Amino-4'-chlor-1,1'-diphenyl-          sulfid-2-sulfonsäure    werden in 250 Teilen  Wasser mit der nötigen Menge 10     o/oiger          Sodalösung    in Lösung gebracht. Zu dieser  Lösung gibt man 30 Teile kristallisiertes       Natriumacetat    hinzu und leitet bei 40-50 o C       Phosgen    ein, bis eine Probe kein freies Amin    mehr anzeigt. Hierauf wird das     Natriumsalz     des neuen     Harnstoffderivates    durch Zusatz  von Kochsalz abgeschieden. Es wird nach  dem Abtrennen, Trocknen und Mahlen als  helles, gut wasserlösliches Pulver erhalten.  Die Ausbeute ist quantitativ.



  Process for the preparation of a urea derivative. The subject of the present patent is a process for the preparation of a urea derivative of the formula
EMI0001.0003
    characterized in that 4-amino-4'-chloro-1,1'-diphenylsulfide-2-sulfonic acid is reacted with phosgene. The new urea derivative forms a pale, water-soluble powder as a sodium salt, which is suitable for use as a moth repellent.



  <I> Example: </I> 20 parts of 4-amino-4'-chloro-1,1'-diphenylsulfide-2-sulfonic acid are dissolved in 250 parts of water with the necessary amount of 10% sodium carbonate solution. 30 parts of crystallized sodium acetate are added to this solution and phosgene is passed in at 40-50 ° C. until a sample no longer shows any free amine. The sodium salt of the new urea derivative is then deposited by adding common salt. It is obtained as a pale, readily water-soluble powder after it has been separated off, dried and ground. The yield is quantitative.
