Description

  

  Verfahren zur Herstellung eines neuen Kondensationsproduktes.    Es wurde gefunden, dass man zu einem  neuen Kondensationsprodukt gelangt, wenn  man     ,,c    -     heptadecylbenzimidazolsulfonsaures     Natrium mit     Diäthylcarbaminsäurechlorid     bei erhöhter Temperatur in Abwesenheit von  Wasser behandelt.  



  Die Umsetzung wird zweckmässig in  Gegenwart eines nichtwässerigen Lösungs  mittels, wie     Pyridin,    vorteilhaft bei etwa  100  , vorgenommen.  



  Das neue Kondensationsprodukt bildet  eine feste Masse, die nach dem Neutralisie  ren in Wasser     leicht    löslich ist. Es besitzt  eine bessere Säurebeständigkeit und eine be  deutend grössere Netzfähigkeit als das Aus  gangsmaterial und kann als     Tegtilhilfsstoff     verwendet werden.  



  <I>Beispiel:</I>  44,5     Gewichtsteile        ,u-heptadecylbenzimid-          azolsulfonsaures    Natrium werden mit 14 Ge  wichtsteilen     Diäthylcarbaminsäurechlorid    und    110     Volumteilen        Pyridin    während 10 :Stun  den bei 100   verrührt. Nach dem     Abdestil-          lieren    des     Pyridins    im Vakuum wird eine       zähflüssige,    Masse erhalten.

   Diese wird     in     600     Volumteilen    heissem Wasser gelöst, mit       ,Sodalösung    neutral gestellt und letztere im  Vakuum     .ein-gedampft    und der Rückstand  bei 100   getrocknet. Das Umsetzungspro  dukt, eine     feste,    in Wasser leicht lösliche  Masse, besitzt eine     bessere    Säurebeständig  keit und eine bedeutend     .grössere    Netzfähig  keit als das Ausgangsmaterial.



  Process for the production of a new condensation product. It has been found that a new condensation product is obtained if sodium c-heptadecylbenzimidazolesulfonic acid is treated with diethylcarbamic acid chloride at an elevated temperature in the absence of water.



  The reaction is conveniently carried out in the presence of a non-aqueous solvent such as pyridine, advantageously at about 100%.



  The new condensation product forms a solid mass that is easily soluble in water after neutralization. It has a better acid resistance and a significantly greater wetting ability than the starting material and can be used as a Tegtilhilfsstoff.



  <I> Example: </I> 44.5 parts by weight of sodium u-heptadecylbenzimidazolesulfonic acid are stirred with 14 parts by weight of diethylcarbamic acid chloride and 110 parts by volume of pyridine for 10 hours at 100. After the pyridine has been distilled off in vacuo, a viscous mass is obtained.

   This is dissolved in 600 parts by volume of hot water, made neutral with soda solution and the latter is evaporated in vacuo and the residue is dried at 100%. The conversion product, a solid, easily soluble mass in water, has a better acid resistance and a significantly greater wetting ability than the starting material.
