Description
Verfahren zur Herstellung eines Oktodecylalkohols. Im Hauptpatent ist ein Verfahren zur Herstellung eines Dodecylalkohols beschrie ben, bei dein man einen Ester der Laurin- säure unter Anwendung von Hydrierungs- katalysatoren bei Temperaturen zwischen <B>150</B> und 400' C mit einem Überschuss an Wasserstoff bis zur Umwandlung der Carboxylgruppe in die -CH2OH-Gruppe be handelt.
Es wurde nun gefunden, dass man einen bekannten 0ktodecylalkohol, der als Zwischenprodukt für die Herstellung von Textilhilfsmitteln und dergl. Verwendung finden soll, erhalten kann, wenn man Stearin säure unter Anwendung von Hydrierungs- katalysatoren bei Temperaturen zwischen <B>150</B> und 400' C mit Wasserstoff behandelt. Für das vorliegende Verfahren eignen sich die gleichen Katalysatoren, wie sie im Haupt patent beschrieben sind. Auch für das vor liegende Verfahren können sowohl die ein fachen Hydrierungskatalysatoren, z.
B. die Metalle der Eisengruppe, wie Kobalt oder Nickel, in sehr fein verteilter Form ver wendet werden, als auch durch besondere Massnahmen aktivierte Katalysatoren oder Mischkatalysatoren, z. B. solche, die Kupfer, Kobalt, Mangan, Zink und Chrom enthalten. Im Falle der Hydrierung von Stearinsäure, die Kontaktgifte enthält, ist es zweckmässig, giftfeste Katalysatoren, beispielsweise sol che, die Molybdän oder seine Verbindungen für sich oder in Mischung mit andern Stof fen enthalten, zu verwenden.
Die Stearinsäure kann gemäss dem Ver fahren der Erfindung sowohl in gasförmigem, als auch flüssigem Zustand reduziert werden. Man kann hierbei auch in Gegenwart von Lösungs- oder Verdünnungsmitteln, z. B. niedr7gmolekularen aliphatischen Alkoholen, arbeiten, wobei jedoch die Anwendung von Druck erforderlich ist.
Zur Durchführung des vorliegenden Verfahrens können auch die durch Verseifung von Fetten erhältlichen Fettsäuregemische, die in der Hauptsache aus Stearinsäure bestehen,- verwendet werden. Für das vorliegende Verfahren lässt sich auch eine Stearinsäure verwenden, die aus deri der. Stearinsäure entsprechenden ungesättigten Karbonsäuren, z.
B. der in Ölen vorkom menden Linolsäure, erhalten wurde. In die sem Falle ist es zweckmässig, solche Kata lysatoren zu verwenden, die neben der Hydrierung der Carbogylgxuppe auch eine Hydrierung von olefinischen Doppelbindun gen bewirken, beispielsweise Katalysatoren, die erhebliche Mengen an Kupfer, Nickel oder Kobalt enthalten. Man kann mit sol chen Katalysatoren aus durch Verseifung von Ölen, z. B.
Olivenöl, Sojaöl und dergl., erhältlichen Bettsäuregemischen zunächst Stearinsäure herstellen und diese dann un- mittelbar .darauf zu Oktodecylalkohol redu zieren.
Oftmals ist es zweckmässig, bei der Hydrierung in gasförmiger Phase dem Wasserstoff oder der zu hydrierenden Sub stanz andere Gase oder Dämpfe, z. B. Wasserdampf, Alkoholdampf, Stickstoff, Kohlensäure etc., zuzusetzen. Bei dem vor liegenden 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 reduzierten Stearinsäure gebildet sind.
Diese wachsartigen Produkte können als Er satz von Bienenwachs imd dergl. verwendet oder ebenfalls in Oktodecylalkohol umgewan delt werden.
<I>Beispiel.</I> Stearinsäure wird mit<B>3,%</B> eines Kataly- sators, welcher aus Kobaltkarbonat, das 2. % Kaliumnitrit enthält, durch 36stündiges Re duzieren im Wasserstoffstrom bei NO' C dargestellt wird, versetzt und sodann bei 135 C mit Wasserstoff von 200 Atm. Druck behandelt, bis keine Wasserstoffaufnahme mehr erfolgt.
Das erhaltene Rohprodukt wird durch Filtration vom Katalysator ge- trennt, wobei es zur Erzielung eines guten Vakuums nötig ist, den Katalysator restlos zu entfernen, da er sonst auf das Destilla- tionsprodukt dehydrierend einwirkt. Die De stillation des Reaktionsproduktes liefert hauptsächlich Oktodecylalkohol vom Siede punkt 203 bis 2'10( C bei 11 mm Druck (Schmelzpunkt 56 C).
Das bei der Destil lation eventuell zurückbleibende Wachs, der Oktodecylester der Stearinsäure, kann erneut der Reduktion unterworfen werden, so dass die Ausbeute an Alkohol praktisch vollstän dig ist. Bricht man die Reduktion ab, wenn die Verseifungszahl auf die Hälfte der ur sprünglichen Säurezahl gefallen ist, so liegt nahezu reines Oktodecylstearat vor.
Verwendet man Ölsäure und den oben beschriebenen Katalysator, so erfolgt zu nächst eine Hydrierung der Doppelbindung und sodann die Hydrierung der Carbogyl- gruppe. Man erhält auch so den Oktodecyi- alkohol in guter Ausbeute.
Process for the production of an octodecyl alcohol. The main patent describes a process for producing a dodecyl alcohol, in which an ester of lauric acid is used using hydrogenation catalysts at temperatures between 150 and 400 ° C. with an excess of hydrogen until conversion the carboxyl group in the -CH2OH group.
It has now been found that a known octodecyl alcohol, which is intended to be used as an intermediate for the production of textile auxiliaries and the like, can be obtained if stearic acid is used using hydrogenation catalysts at temperatures between 150 and 400 'C treated with hydrogen. The same catalysts as described in the main patent are suitable for the present process. Even for the present process, both the simple hydrogenation catalysts, such.
B. the metals of the iron group, such as cobalt or nickel, are used ver in very finely divided form, as well as catalysts activated by special measures or mixed catalysts, eg. B. those that contain copper, cobalt, manganese, zinc and chromium. In the case of the hydrogenation of stearic acid, which contains contact poisons, it is expedient to use poison-resistant catalysts, for example those containing molybdenum or its compounds by themselves or in a mixture with other substances.
According to the method of the invention, the stearic acid can be reduced in both the gaseous and liquid state. 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 obtainable by saponification of fats, which mainly consist of stearic acid, can also be used to carry out the present process. A stearic acid derived from deri can also be used for the present process. Stearic acid corresponding unsaturated carboxylic acids, e.g.
B. the in oils vorkom coming linoleic acid was obtained. In this case it is expedient to use catalysts which, in addition to the hydrogenation of the Carbogylgxuppe also bring about a hydrogenation of olefinic double bonds, for example catalysts which contain considerable amounts of copper, nickel or cobalt. You can with sol chen catalysts by saponification of oils, for. B.
Olive oil, soybean oil and the like, available bed acid mixtures first produce stearic acid and then immediately reduce it to octodecyl alcohol.
Often it is expedient in the hydrogenation in the gaseous phase to the hydrogen or the substance to be hydrogenated, other gases or vapors, eg. B. water vapor, alcohol vapor, nitrogen, carbonic acid, etc., add. 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 reduced stearic acid.
These waxy products can be used as a replacement for beeswax and the like, or can also be converted into octodecyl alcohol.
<I> Example. </I> Stearic acid is produced with <B> 3.% </B> of a catalyst made from cobalt carbonate containing 2.% potassium nitrite by reducing it for 36 hours in a hydrogen stream at NO'C , and then at 135 C with hydrogen of 200 atm. Treated pressure until no more hydrogen absorption occurs.
The crude product obtained is separated from the catalyst by filtration, it being necessary to remove the catalyst completely in order to achieve a good vacuum, since otherwise it has a dehydrogenating effect on the distillation product. The distillation of the reaction product mainly gives octodecyl alcohol from boiling point 203 to 2'10 (C at 11 mm pressure (melting point 56 C).
The wax that may remain after the distillation, the octodecyl ester of stearic acid, can be subjected to the reduction again so that the alcohol yield is practically complete. If the reduction is stopped when the saponification number has fallen to half of the original acid number, the result is almost pure octodecyl stearate.
If oleic acid and the catalyst described above are used, the double bond is hydrogenated first and then the carbogyl group is hydrogenated. The octodecyl alcohol is also obtained in this way in good yield.
