  <B>Zusatzpatent.</B> zum     Hauptpatent    Nr. 220744.    Verfahren zur Herstellung eines neuen Derivats der     technischen        Stearinhydroxamsäure.       Es wurde     gefunden,    dass man zu einem  neuen Derivat der technischen     Stearinhydro-          xamsäure    gelangt, wenn man technische     Stea-          rinhydroxamsäure    mit einer den Säurerest  
EMI0001.0009     
    abgebenden Verbindung behandelt.  
EMI0001.0010     
  
     abgebende Verbindung kann man z.

   B.     Benzoe-          säure-m-sulfochlorid    oder     Benzoylchlorid-m-          sulfosäure    verwenden.  



  Die Umsetzung     wird    zweckmässig bei er  höhter Temperatur, z. B.<B>700,</B> vorteilhaft in  Gegenwart eines säurebindenden Mittels, wie       Pyridin,    vorgenommen.    Das neue Derivat der technischen     Stearin-          hydroxamsäure    ist ein schwach gelb gefärbtes  Pulver, das in Wasser und in verdünnten       wässrigen        Alkalien    löslich ist. Es kann als       Textilhilfsstoff,    z. B.     zum    waschechten Wasser  abstossendmachen von Fasermaterialien, ver  wendet werden.  



  <I>Beispiel:</I>  13 Gewichtsteile     Benzoesäure-m-sulfochlo-          rid    werden mit     100        Gewichtsteilen        Pyridin     bei<B>70"</B> während einer     hälben    Stunde ver  rührt. Nach dem Abkühlen auf 5   werden  14 Gewichtsteile einer     technischen    Stearin  hydroxamsäure zugegeben. Nach dem Weiter  rühren während einigen     Stunden    bei Raum  temperatur     wird    das Gemisch kurze Zeit auf  30   erwärmt, wobei eine klare, fast farblose  Lösung entsteht.

   Diese     wird    in eine     Mischung     aus 85 Gewichtsteilen     konzentrierter        Salz-          säure    (D -1,19), 50 Gewichtsteilen gesät  tigter Kochsalzlösung und 150     Gewichtsteilen     Eis unter Rühren ausgegossen. Der etwas  schmierige Niederschlag wird nach einiger  Zeit     abfiltriert,    zweimal mit 1     %iger    Salz-           säure    und dann mit Wasser gewaschen, bis  das Waschwasser kongoneutral ist.

   Nach dem  Trocknen bei 40' im Vakuum wird das neue  Produkt als schwach gelb gefärbtes Pulver  erhalten, das sich gut pulverisieren lässt und  in Wasser und in verdünnten     wässrigen        Al-          kalien    löslich ist.



  <B> Additional patent. </B> to main patent no. 220744. Process for the production of a new derivative of technical stearic hydroxamic acid. It has been found that a new derivative of technical stearic hydroxamic acid is obtained if technical stearic hydroxamic acid is used with an acid residue
EMI0001.0009
    handing out connection.
EMI0001.0010
  
     delivering connection can be z.

   B. Use benzoic acid-m-sulfochloride or benzoyl chloride-m-sulfonic acid.



  The reaction is conveniently carried out at an elevated temperature, e.g. B. 700, is advantageously carried out in the presence of an acid-binding agent such as pyridine. The new derivative of technical stearic hydroxamic acid is a pale yellow powder that is soluble in water and in dilute aqueous alkalis. It can be used as a textile auxiliary, e.g. B. to make real water repellent of fiber materials are used ver.



  <I> Example: </I> 13 parts by weight of benzoic acid m-sulfochloride are stirred with 100 parts by weight of pyridine at <B> 70 "</B> for half an hour. After cooling to 5, 14 parts by weight of a technical Stearic hydroxamic acid was added After stirring for a few more hours at room temperature, the mixture was briefly heated to 30, a clear, almost colorless solution being formed.

   This is poured into a mixture of 85 parts by weight of concentrated hydrochloric acid (D -1.19), 50 parts by weight of saturated sodium chloride solution and 150 parts by weight of ice with stirring. The somewhat greasy precipitate is filtered off after some time, washed twice with 1% hydrochloric acid and then with water until the wash water is Congo-neutral.

   After drying at 40 'in a vacuum, the new product is obtained as a pale yellow colored powder, which can be pulverized easily and is soluble in water and in dilute aqueous alkalis.
