Description

  

  Verfahren zur Herstellung eines neuen Textilhilfsmittels.    Es wurde gefunden, dass man ein neues       Textilhilfsmittel    erhält, wenn man     m-Amino-          cyclohexanol    mit     Laurinsäurechlorid    behan  delt und das so -erhältliche Produkt mit     kon-          zentrierter    Schwefelsäure umsetzt. Nach der  Neutralisation bildet das neue Produkt in  trockenem Zustande ein weisses Pulver, das  sich in Wasser leicht löst. Die wässerige  Lösung zeigt ein hohes Netz-,     Emulgier-    und       Waschvermögen.     



       Beispiel:     24 Teile     m-Aminocyclohexanol    werden in  100 Teilen 4fach normaler wässeriger Na  triumacetatlösung gelöst und unter Eisküh  lung und gutem Rühren mit 42 Teilen       Laurinsäurechlorid    versetzt. Es entsteht eine  dicke Fällung. Die Masse wird nun langsam  unter starkem Rühren     erwärmt,    bis     sie,    sich  etwas zusammengeballt hat und     filtrierbar     wird. Sie wird nun     abfiltriert    und mit Was  ser gewaschen und getrocknet.

   Das so er  haltene Produkt bildet ein weisses Pulver,  das in Wasser unlöslich ist. 20 Teile     des     Produktes werden unter Rühren bei Zimmer  temperatur in 100 Teile 96     bis    98     %ige       Schwefelsäure eingetragen und so lange ver  rührt, bis die Masse in Wasser löslich ist.  Man giesst nun in eine Kältemischung, trennt  die ausgeschiedene Masse vom Wasser, zum  Beispiel .durch Filtrieren. Das Produkt wird  nun mit Alkalien, zum Beispiel     Natriumoar-          bonat,    neutralisiert und eingetrocknet, es  kann auch als wässerige Paste     verwendet     werden. Das Salz bildet in trockenem Zu  stande ein weisses Pulver, das sieh in Was  ser leicht löst.



  Process for the production of a new textile auxiliary. It has been found that a new textile auxiliary is obtained if m-amino-cyclohexanol is treated with lauric acid chloride and the product thus obtainable is reacted with concentrated sulfuric acid. After neutralization, the new product forms a white powder when dry, which easily dissolves in water. The aqueous solution shows high wetting, emulsifying and washing power.



       Example: 24 parts of m-aminocyclohexanol are dissolved in 100 parts of 4-fold normal aqueous sodium acetate solution, and 42 parts of lauric acid chloride are added with ice cooling and thorough stirring. A thick precipitate is formed. The mass is now slowly heated while stirring vigorously until it has clumped a little and can be filtered. It is then filtered off and washed with water and dried.

   The product obtained in this way forms a white powder that is insoluble in water. 20 parts of the product are introduced into 100 parts of 96 to 98% strength sulfuric acid with stirring at room temperature and the mixture is stirred until the mass is soluble in water. It is then poured into a cold mixture, the precipitated mass is separated from the water, for example by filtering. The product is then neutralized with alkalis, for example sodium carbonate, and dried. It can also be used as an aqueous paste. When dry, the salt forms a white powder that dissolves easily in water.
