Description
<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

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.
