Description

  

  Verfahren zur Herstellung eines wasserlöslichen Abkömmlings  der     beteroeyelischen    Reihe.    Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung eines     quater-          nKren        Indolderivates,    welches dadurch ge  kennzeichnet ist, dass man     2-Heptadecyl-2,3-          dihydroindol    mit     Dimethylsulfat    und das er  haltene Produkt hierauf mit     Glycerinmono-          chlorhydrin,    enthaltend ein Gemisch der     a-          und        ss-Isomeren,        behandelt.     



  Die neue     Verbindung    wird als zähflüssi  ges 01 erhalten, das sich in Wasser farblos  auflöst und das ein gutes     Carbonisiernetzmit-          tel    und     Mittel    zum Verbessern der Wasser  echtheit von Direktfärbungen ist und     starke          fungicide    und     bactericide    Wirkung besitzt.  Die     wässrige        Lösung    besitzt gute     kapillarak-          tive    Eigenschaften.  



  <I>Beispiel:</I>  34 g     2-Heptadecyl-2,3-dihydroindol,        in    be  kannter Weise aus     2-Heptadecylindol    darge  stellt, werden     in    100     cm$    Chlorbenzol gelöst  und 17 g     Natriumcarbonat        zugegeben.    Bei  100   C werden 20 g     Dimethylsulfat        zuge-          tropft        und    6     Stunden    auf 120   erhitzt.

   Dar-    auf werden 12 g     Glycerinmonochlorhydrin,     enthaltend     ein    Gemisch der a-     und        ss-Iso-          meren    eingetropft und weitere 6     Stunden    bei  120   C gehalten. Nachher wird von den un  gelösten, anorganischen Salzen     abfiltriert,     das Chlorbenzol mit Wasserdampf abge  blasen     und    die     wässrige    Lösung     im    Vakuum  eingedampft.

   Man erhält     ein        zähflüssiges    01,  das in Wasser sich farblos auflöst und das  ein gutes     Carbonisiernetzmittel    und     Mittel     zum     Verbessern    der     Wasserechtheit    von  Direktfärbungen ist und starke     fungicide    und       bactericide    Wirkungen besitzt. Die     wässrige          Lösung    besitzt gute     kapillaraktive    Eigen  schaften.



  Process for the preparation of a water-soluble derivative of the Beteroeyelic series. The subject of the present patent is a process for the production of a quater- nKren indole derivative, which is characterized in that 2-heptadecyl-2,3-dihydroindole is mixed with dimethyl sulfate and the product obtained thereupon with glycerol monochlorohydrin, containing a mixture of a - and ss-isomers.



  The new compound is obtained as a viscous oil which dissolves colorlessly in water and which is a good carbonizing wetting agent and agent for improving the water fastness of direct dyeings and has a strong fungicidal and bactericidal effect. The aqueous solution has good capillary-active properties.



  <I> Example: </I> 34 g of 2-heptadecyl-2,3-dihydroindole, prepared in a known manner from 2-heptadecylindole, are dissolved in 100 cm $ chlorobenzene and 17 g of sodium carbonate are added. 20 g of dimethyl sulfate are added dropwise at 100 ° C. and the mixture is heated to 120 for 6 hours.

   12 g of glycerol monochlorohydrin, containing a mixture of the α and β isomers, are then added dropwise and kept at 120 ° C. for a further 6 hours. The un dissolved inorganic salts are then filtered off, the chlorobenzene is blown with steam and the aqueous solution is evaporated in vacuo.

   A viscous oil is obtained which dissolves colorlessly in water and which is a good carbonizing wetting agent and agent for improving the waterfastness of direct dyeings and which has strong fungicidal and bactericidal effects. The aqueous solution has good capillary-active properties.
