Description
Terfahren zur Herstellung eines Oktodekandiols. Im Hauptpatent ist ein Verfahren zur Herstellung eines Dodecylalkohols beschrie ben, bei dem man einen Ester der Laurin- säure unter Anwendung von Hydrierungb- katalysatoren bei Temperaturen zwischen <B>1.50</B> und 400,'<B>C</B> mit einem Übe-rso,1-iuss an Wasserstoff bis zur Umwandlung der Carboxylgruppe in die -CH--,OH-Gruppe be handelt.
Es wurde nun aefunden, dass' man ein Oktodekandiol erhalten 'Kann, wenn man RieinolsiLure unter Anwendung von Hydrie- rungskatalysatoren bei Temperaturen zwi- sehen <B>150</B> und 4001 <B>C</B> mit Wasserstoff be handelt. Für das vorlie-ende Verfahren eignen sieh die gleichen Katalysatoren, wie sie, im Hauptpatent beschrieben sind.
Auch für das vorliegende Verfahren können so wohl die einfachen Hydrierungskatalysato- ren, zum Beispiel die Metalle der Eisen gruppe, wie Kobalt oder Niak#el, in sehr fein verteilter Form verwendet werden, als auch durch besondere Massnahmen aktivierte Ka talysatoren oder Misclikatalysatoren, zum Beispiel solche, die Kupfer, Kobalt, Mangan, Zink und Chrom enthalten.
Im Falle der Hydrierung von Ricinolsäure, die Kontakt- 01 fte enthält, ist es zweckmässig, giftfeste ei ZD Katalysatoren, beispielsweise solehe, die Molybdän oder seine Verbindungen für sich oder in Mischun- mit andern Stoffen ent halten, zu verwenden. Die Ricinolsäure kann gemäss dein Ver fahren der Erfindung sowohl in gasförmiger, als auch flüssiger Phase reduziert werden. Man arbeitet zweckmässig unter erhöllteia Druck.
Man kann hierbei auch in Gegen-' wart von Lösungs- oder Verdünnungsmitteln, z. B. niedrigmolekularen aliphatisehen <B>Al-</B> koholen, arbeiten, wobei jedoch die Anwen dung von Druck erfürderlieli ist. Zur Durch führung des vorliegenden' Verfahrens kön nen auch die durch Verseifung von Rizinus <B>öl</B> erhältlichen Fettsäuregemische, welche wesentliche Mengen Ricinolsäure enthalten, verwendet werden. Oftmals ist es zweck mässig, bei der Hydrierung in gasförmiger Phase dem Wasserstoff oder der zu hydrie renden Substanz andere Gase oder Dämpfe, z. B.
Wasserdampf, Alkoholdampf, Stiel,-- stoff, KohlenAure etc-, zuzusetzen. Bei dem vorliegenden Verfahren entstehen ebenso wie bei dem Verfahren des Hauptpatentes häufig als Nebenprodukte wachsartige Produkte von sehr wertvollen Eigenschaften, die durch Esterbildung aus dem entstandenen hoch molekularen Alkohol und der noch nicht hydrierten Rieinolsäure gebildet sind.
Diese wachsartigen Produkte können als Ersatz für natürliche Wachse und dergl. verwendet oder ebenfalls in das Oktodekandiol um- 01 andelt werden.
Z>ew Das gemäss dem Verfahren der Erfindung hergestellte Oktodekandiol ist bereits be- ka,unt. Es soll als Zwischenprodukt bei der Herstellung von Textilhilfsmitteln und dergl. 'Verwendung finden.
<I>Beispiel.</I> - Kobaltnitratlösung wird bei Raumtem peratur mit gesättigter Ammeniumbikarbo- natlösung gefällt. Nach dem Auswaschen mit Wasser und scharfen Absaucen des Ko- baltkarbonates wird dieses mit so viel 5%iger Ätzkalilösung angeteigt, dass das Gemisch<B>3</B> Mol-Prozent Ätzkali, bezogen auf das Kobalt, enthält.
Hierauf wird das so hergestellte Gemisch. im Vakuum bei<B>100 ' C</B> oletrocknet, fein gemahlen und bei<B>325</B> bis <B>350' C</B> im Wasserstoffstrom reduziert.
Behandelt man technische Rieinolsätirv, die durch> Verseifen von Rizinusöl gewonnen wurde, bei<B>230 ' C</B> in Gegenwart des in der oben beschriebenen Weise erhältlichen Katalysators unter gutem Rühren so lange mit Wasserstoff von 200 Atm., bis praktisch keine Druckabnahme mehr stattfindet, so er hält man ein helles, hartes Reaktionsprodukt, dessen Verseifungszahl kleiner als 2 ist.
Die Destillation im Vakuum liefert in eiiier Ausbeute von über<B>95</B> go' ein rein weisses De- stillat, das aus einem Gemiseli von Alk-6holen bestellt, welches dem Säuregemisch. der iii dem Rizinusöl vorhandenen Säuren entspricht. Durch fraktionierte Destillation im Vakuum lässt sich aus dem Destillat etwa<B>80</B> Iwo Okto- dekandiol gewinnen, das unter beträchtlicher Kontraktion zu einer glänzenden kristallinen Masse erstarrt, die bei<B>6,6 ' C</B> schmilzt.
Mit dem gleichen Effekt lässt sich die Hydrierung der Säuren aus dem Rizinusöl auch mit andern, zum Beispiel den im Haupt patent erwähnten Katalysatoren ausführen.
Terfahren for the production of an octodecanediol. The main patent describes a process for the production of a dodecyl alcohol in which an ester of lauric acid is used using hydrogenation catalysts at temperatures between 1.50 and 400 ° C treated with an excess of hydrogen until the carboxyl group is converted into the -CH -, OH group.
It has now been found that 'one can obtain an octodecanediol' if one treats Rieinolsilure with hydrogen using hydrogenation catalysts at temperatures between <B> 150 </B> and 4001 <B> C </B> . The same catalysts as described in the main patent are suitable for the present process.
The simple hydrogenation catalysts, for example the metals of the iron group such as cobalt or niak # el, can also be used in very finely divided form for the present process, as well as catalysts activated by special measures or misclic catalysts, for example those that contain copper, cobalt, manganese, zinc and chromium.
In the case of the hydrogenation of ricinoleic acid, which contains contact oil, it is advisable to use poison-resistant ei ZD catalysts, for example sols which contain molybdenum or its compounds alone or in mixtures with other substances. The ricinoleic acid can be reduced according to your method of the invention both in the gaseous phase and in the liquid phase. One works expediently under extreme pressure.
You can also in the presence of solvents or diluents such. B. low molecular weight aliphatic alcohols, work, but the application of pressure is required. The fatty acid mixtures which can be obtained by saponifying castor oil and which contain substantial amounts of ricinoleic acid can also be used to carry out the present process. Often it is useful in the hydrogenation in the gaseous phase to the hydrogen or the substance to be hydrie-generating other gases or vapors, eg. B.
To add water vapor, alcohol vapor, stem, substance, carbonic acid, etc. In the present process, as in the process of the main patent, waxy products with very valuable properties often arise as by-products, which are formed by ester formation from the high molecular weight alcohol and the not yet hydrogenated rioline acid.
These waxy products can be used as a substitute for natural waxes and the like, or they can also be converted into octodecanediol.
Z> ew The octodecanediol produced according to the process of the invention is already known, untill. It should be used as an intermediate in the production of textile auxiliaries and the like.
<I> Example. </I> - Cobalt nitrate solution is precipitated at room temperature with saturated ammonium bicarbonate solution. After washing the cobalt carbonate with water and hot sauces, it is made into a paste with so much 5% caustic potash solution that the mixture contains <B> 3 </B> mol percent caustic potash, based on the cobalt.
The mixture thus produced is then used. Oil-dried in a vacuum at <B> 100 'C </B>, finely ground and reduced in a stream of hydrogen at <B> 325 </B> to <B> 350' C </B>.
If technical Rieinolsätirv, which was obtained by> saponification of castor oil, at <B> 230 ° C </B> in the presence of the catalyst obtainable in the manner described above with good stirring with hydrogen of 200 atm., Until practically none Pressure decrease takes place more, so he keeps a light, hard reaction product whose saponification number is less than 2.
The distillation in vacuo delivers a pure white distillate in a yield of over 95%, which is ordered from a Gemiseli of Alk-6haben, which is the acid mixture. which corresponds to the acids present in castor oil. By fractional distillation in vacuo, about <B> 80 </B> Iwo octodecanediol can be obtained from the distillate, which solidifies under considerable contraction to form a shiny crystalline mass that is <B> 6.6 'C </B> melts.
The hydrogenation of the acids from castor oil can also be carried out with other catalysts, for example the catalysts mentioned in the main patent, with the same effect.
