Description

  

      Verfahren    zur Herstellung eines neuen     Tegtilhilfsproduktes.       Es wurde gefunden, dass man eine neue       Sulfonsäure    erhält, wenn man das     ,u-n-Hep-          tadecylbenzimidazol,    das beispielsweise ent  steht durch Kondensieren von     o-Phenylen-          diamin    mit     Stearinsäure,    zunächst einer     Me-          thylierung    durch Behandeln im geschlossenen  Gefäss mit überschüssigem     Chlormethyl    bei  Temperaturen, die zwischen 140 und<B>180'</B>  liegen,

   unterwirft und hierauf das so erhal  tene Produkt mit     sulfierend    wirkenden Mitteln  behandelt.  



  Die so erhaltene     Sulfonsäure    bildet in  Form ihrer     Alkalisalze    ein kaum gefärbtes  Pulver, dessen wässerige Lösungen hervor  ragende     kapillaraktive    Eigenschaften auf  weisen.  



  <I>Beispiel:</I>  Zu 71 Teilen     ss-n-Heptadecylbenzimidazol     werden in einem     Autoklaven    30 Teile Chlor  methyl gepresst, worauf das Reaktionsgemisch  während 14 Stunden auf 155-1600 erhitzt  wird. Nach dem Erkalten bildet das Reak  tionsprodukt eine feste fettige Masse, die in  Wasser spielend löslich ist.    200 Teile des so erhaltenen     Methylierungs-          produktes    werden zu 400 Teilen Schwefel  säure bei<B>10-15'</B> allmählich zugefügt.

   Nach  dem eine homogene Mischung entstanden ist,  kühlt man das Gemisch auf     --f-    5 0 ab und  führt nun die     Sulfonierung    bei     -(-    5 0 bis  10          durch, indem man langsam 380-385       Teile        Oleum        (24%        SO,        9-Gehalt)        zufliessen     lässt. Die     Sulfonierung    ist beendet, wenn eine  Probe der Masse in verdünnter     Natriumcar-          bonatlösung    völlig klar löslich ist.

   Nun giesst  man die     Sulfonierungsmasse    unter Rühren  auf 2400 Teile Eis, wobei die     Sulfonsäure     ausfällt und von der wässerigen Schwefel  säure     abfiltriert    und gewaschen werden kann.  Nach dem Neutralisieren der so erhaltenen       Sulfonsäure    mit     Natriumhydroaydlösung    und  Eindampfen der Lösung im Vakuum erhält  man das     Natriumsalz    der     Sulfosäure    als ein  in Wasser sehr leicht lösliches Pulver.



      Process for the production of a new Tegtil auxiliary product. It has been found that a new sulfonic acid is obtained if the un-heptadecylbenzimidazole, which is formed, for example, by condensing o-phenylenediamine with stearic acid, is first methylated by treating it in a closed vessel with excess chloromethyl Temperatures between 140 and <B> 180 '</B>,

   and then treated the product obtained in this way with sulphurizing agents.



  The sulfonic acid obtained in this way, in the form of its alkali metal salts, forms a hardly colored powder, the aqueous solutions of which have excellent capillary-active properties.



  <I> Example: </I> To 71 parts of ss-n-heptadecylbenzimidazole, 30 parts of chloromethyl are pressed in an autoclave, whereupon the reaction mixture is heated to 155-1600 for 14 hours. After cooling, the reaction product forms a solid, fatty mass that is easily soluble in water. 200 parts of the methylation product thus obtained are gradually added to 400 parts of sulfuric acid at <B> 10-15 '</B>.

   After a homogeneous mixture has formed, the mixture is cooled to --f- 5 0 and the sulfonation is now carried out at - (- 5 0 to 10 by slowly adding 380-385 parts of oleum (24% SO, 9- The sulfonation is complete when a sample of the mass is completely soluble in dilute sodium carbonate solution.

   The sulfonation mass is then poured onto 2400 parts of ice with stirring, the sulfonic acid precipitating and the aqueous sulfuric acid can be filtered off and washed. After neutralizing the sulfonic acid obtained in this way with sodium hydroxide solution and evaporating the solution in vacuo, the sodium salt of the sulfonic acid is obtained as a powder which is very easily soluble in water.
