Description
Verfahren zur Herstellung eines aktiven Sauerstoff enthaltenden Waschmittels. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung eines _ be ständigen, aktiven Sauerstoff abgebenden Waschmittels, das dadurch gekennzeichnet ist, dass man das Natriumsalz des durch Einwirkung von weniger als der moleku laren Menge Pyrophosphorsäure auf Cetyl- alkohol erhältlichen Cetylalkoholpyrophos- phorsäureesters mit Wasserstoffsuperoxyd behandelt.
<I>Beispiel:</I> 260 kg Cetylalkohol werden mit 90 kg reiner Pyrophosphorsäure bei 100 bis<B>110'</B> verestert.
Darauf wird das Reaktionsgemisch mit 40 kg @ Ätznatron neutralisiert und durch Umkristallisieren aus Alkohol und Äther der reine Natriumpyrophosphorsäureester von folgender Formel erhalten: R2Na2P20." wobei "R" den Alkoholrest darstellt. 664 kg von dem so hergestellten Alkoholpyrophos- phorsäureester werden mit 215 1 Wasser stoffsuperoxyd 40 % ig angeteigt und unter Zugabe von wenig Alkohol bei 40 in Lö sung gebracht.
Hierbei bildet sich analog dem Persalz, des Natriumpyrophosphates ein Anlagerungsprodukt in Form einer weissen Paste, in welchem 2i/2 Mol Wasserstoffsuper oxyd auf 1 Mol des Alkoholnatriumpyro- phosphates kommt.
Um zu einem trockenen Produkt zu ge langen, ist es zweckmässig, den Alkohol vor sichtig im Vakuum abzudampfen und den Rückstand in Äther aufzunehmen. Dabei fällt das Anlagerungsprodukt als weisses kör niges, kristallines Salz aus, welches abfil- triert und mit Äther nachgewaschen werden kann. Das erhaltene Produkt besitzt einen ungefähren Gehalt von 62 ,wo Fett und 5 aktivem Sauerstoff und ist leichter wasser löslich als der Fettalkoholpyrophosphorsäure- ester und bildet sowohl als Paste als auch als Pulver mit Wässer stark schäumende Lösungen.
Das Produkt kann ausser für die allge meinen Zwecke vor allem auch bei der Tex tilveredlung zum oxydativen Nachseifen, zum Vorbleichen von Farbware, zum Keu chen und Nachbleichen von Baumwolle, zum Entbasten von Rohseide, zum Aufschliessen von Stärke und ähnlichen Zwecken nutzbrin gend Verwendung finden, zum Beispiel in der Haushaltwäsche.
Process for the preparation of a detergent containing active oxygen. The subject of the present patent is a process for the production of a constant, active oxygen-releasing detergent, which is characterized in that the sodium salt of the cetyl alcohol pyrophosphoric acid ester obtainable by the action of less than the molecular amount of pyrophosphoric acid on cetyl alcohol is treated with hydrogen peroxide.
<I> Example: </I> 260 kg of cetyl alcohol are esterified with 90 kg of pure pyrophosphoric acid at 100 to <B> 110 '</B>.
The reaction mixture is then neutralized with 40 kg of caustic soda and the pure sodium pyrophosphoric acid ester of the following formula is obtained by recrystallization from alcohol and ether: R2Na2P20. "Where" R "represents the alcohol residue. 664 kg of the alcohol pyrophosphoric acid ester prepared in this way are mixed with 215 liters of water Fabric superoxide 40% made into a paste and brought into solution with the addition of a little alcohol at 40%.
Analogous to the persalt, sodium pyrophosphate, an addition product is formed in the form of a white paste in which 2½ moles of hydrogen peroxide are added to 1 mole of alcohol sodium pyrophosphate.
In order to get a dry product, it is advisable to carefully evaporate the alcohol in vacuo and absorb the residue in ether. The adduct precipitates out as a white, granular, crystalline salt, which can be filtered off and washed with ether. The product obtained has an approximate content of 62, where fat and 5 active oxygen and is more soluble in water than the fatty alcohol pyrophosphoric acid ester and forms strongly foaming solutions both as a paste and as a powder with water.
In addition to general purposes, the product can also be used to good effect in textile refinement for oxidative re-soaping, pre-bleaching of colored goods, cooking and re-bleaching of cotton, deboning of raw silk, opening up starch and similar purposes. for example in household linen.
