Description

  

      Verfahren    zur Herstellung eines     Thiosernicarbazons.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines     Thio-          semicarbazons,    das dadurch gekennzeichnet  ist, dass man     Benzaldehyd-4-n-butyl-sulfon     mit     Thiosemicarbazid    umsetzt und das ent  sprechende     Thiosemicarbazon    rein     gewinnt.     



  Die neue Verbindung kann ausser zur  Bekämpfung von     Tuberkuloseinfektionen    auch  zu andern Zwecken, z. B. zur Schädlings  bekämpfung, Verwendung finden.    <I>Beispiel:</I>    22 g     Benzaldehyd-4-n-butylsulfon    werden  in 100     cms        heissem        Alkohol    gelöst und mit  einer heissen Lösung von 10 g     Thiosemicarb-          azid    in 100     cm3    Wasser versetzt. Nach Zu  gabe von 5     cm3    Eisessig wird 30 Minuten ge-    kocht und abgekühlt. Das auskristallisierte       Thiosemicarbazon    wird aus Alkohol umkri  stallisiert.

   Man erhält das     Benzaldehyd-4-n-          butyl    -     sulfon    -     thiosemicarbazon    in schwach  gelblich gefärbten Kristallen vom Schmelz  punkt 194  C.



      Process for the production of a thiosernicarbazone. The present patent relates to a process for the production of a thiosemicarbazone which is characterized in that benzaldehyde-4-n-butyl-sulfone is reacted with thiosemicarbazide and the corresponding thiosemicarbazone is obtained in pure form.



  In addition to combating tuberculosis infections, the new compound can also be used for other purposes, e.g. B. for pest control, use. <I> Example: </I> 22 g of benzaldehyde-4-n-butylsulfone are dissolved in 100 cms of hot alcohol and a hot solution of 10 g of thiosemicarbazide in 100 cm3 of water is added. After adding 5 cm3 of glacial acetic acid, the mixture is boiled for 30 minutes and then cooled. The crystallized thiosemicarbazone is crystallized from alcohol.

   Benzaldehyde-4-n-butyl-sulfone-thiosemicarbazone is obtained in pale yellowish crystals with a melting point of 194 C.
