Description
Verfahren zur Herstellung eines neuen Stearinsäurepolyglykolesters. Es wurde gefunden, dass man zu einem neuen S'tearinsäurepolyglykolester gelangt, wenn man 1 Mol Stearinsäure bei erhöhter Temperatur in Gegenwart eines Katalysa- tors mit etwa 2 Mol Äthylenoxyd umsetzt.
Die Umsetzung mit dem Äthylenoxyd kann z. B. bei 120 bis 180 vorgenommen -werden, vorteilhaft bei 150 bis 1ö.5 . Es ist zweckmässig, das Äthylenoxyd bei der Re- aktionstemperatur in der Weise allmählich in das Reaktionsgemisch einzupressen, dass der Druck in der Gasphase nicht über 4 bis 10 atü steigt.
Als Katalysatoren verwendet man zweckmässig alkalisch reagierende Stoffe, z. B. Alkalihydroxyde, mit besonderem Vor teil jedoch Alkalisalze von organischen Car bon:säuren, vorzugsweise von solchen mit niedrigem Molekulargewicht, wie Natrium acetat oder Natriumbutyrat.
Der neue Stearinsäurepolyglykolester bil det eine feste Masse, die beim Verrühren mit Wasser von 50 zunächst eine Paste bildet und bei weiterem Zusatz von 50 warmem Wasser eine opaleszierende Lösung liefert. Er kann als Textilhilfsstoff, z. B. zum Avi- vieren der Zellwolle, benützt werden.
Beispiel: Man erhitzt 400 Teile Stearinsäure und 8 Teile feingemahlenes, wasserfreies Natrium- aeetat in einem druckfesten Gefäss auf l50 und presst unter Rühren 131 Teile Äthylen- oxyd in kleinen Anteilen bei<B>150</B> bis 155 in der Weise ein, dass der Druck nicht über 10 atü steigt.
Wenn der Überdruck vollstän dig verschwunden ist, rührt man bei der angegebenen Temperatur 1 Stunde nach und lässt erkalten. Das Umsetzungsgut bildet eine feste Masse, die beim Verrühren mit Wasser von 50 zunächst eine Paste bildet und bei weiterem Zusatz von 50 warmem Wasser eine opaleszierende Lösung liefert. Es kann als Textilhilfsstoff, z. B. zum Avivieren der Zellwolle, benützt werden.
Process for the preparation of a new stearic acid polyglycol ester. It has been found that a new polyglycol ester of s'tearic acid is obtained if 1 mole of stearic acid is reacted with about 2 moles of ethylene oxide at an elevated temperature in the presence of a catalyst.
The reaction with the ethylene oxide can, for. B. made at 120 to 180, advantageously at 150 to 1ö.5. It is advisable to gradually inject the ethylene oxide into the reaction mixture at the reaction temperature in such a way that the pressure in the gas phase does not rise above 4 to 10 atmospheres.
The catalysts used are suitably alkaline substances such. B. alkali hydroxides, but with a special part before alkali salts of organic carbon: acids, preferably of those with low molecular weight, such as sodium acetate or sodium butyrate.
The new stearic acid polyglycol ester forms a solid mass which, when mixed with 50 water, initially forms a paste and when further 50 warm water is added, an opalescent solution is obtained. It can be used as a textile auxiliary, e.g. B. for avivating the rayon can be used.
Example: 400 parts of stearic acid and 8 parts of finely ground, anhydrous sodium acetate are heated in a pressure-tight vessel to 150 and, while stirring, 131 parts of ethylene oxide are pressed in in small proportions at 150 to 155 in the manner that the pressure does not rise above 10 atmospheres.
When the excess pressure has completely disappeared, the mixture is stirred at the specified temperature for 1 hour and allowed to cool. The reaction material forms a solid mass which, when mixed with 50 water, initially forms a paste and, with further addition of 50 warm water, produces an opalescent solution. It can be used as a textile auxiliary, e.g. B. can be used to finish the rayon.
