Description
Verfahren zur Herstellung primärer Alkohole. Es ist bekannt, durch Erhitzen eines Ge misches von Calciumsalzen der Fettsäuren mit ameisensaurem Calcium die Aldehyde der Fettreihe darzustellen. Ebenso ist es be kannt, Aldehyde durch katalytische Reduk tion mit Wasserstoff in die entsprechenden primären Alkohole umzuwandeln.
Es wurde nun gefunden, dass sieh die Umsetzung der Calciumsalze der höheren Fettsäuren und der Ameisensäure einerseits und die katalytische Hydrierung der Alde hyde der Fettreihe anderseits auf sehr ein fache und vorteilhafte Weise in einem Ar beitsgang bewerkstelligen lässt und man da durch primäre Alkohole in sehr hoher Aus beute und grosser Reinheit erhält. Die erst genannte Reaktion wird dadurch gefördert und zum vollständigen Ablaufen gebracht, dass die Aldehyde durch die gleichzeitig ver laufende katalytische Reduktion zu den Alkoholen aus dem Reaktionsgemisch ent fernt werden und dadurch das Gleichgewicht der Aldehydbildungsreaktion fortwährend gestört wird.
Es gelingt dadurch, die Alde- hydbildung bei milderen Bedingungen und viel vollständiger durchzuführen, als es bei getrennter Ausführung möglich ist. Nach dem neuen Verfahren kann man von dem Calciumsalz der Laurinsäure über den Lau rinaldehyd zum Laurinalkohol, vom stearin- sauren Calcium über den Stearinaldehyd zum Stearinalkohol gelangen usw. Das Verfah ren wird bei erhöhtem Druck ausgeführt.
Die Temperatur wird zweckmässig etwa zwi schen 150 und 400 C gehalten. Die Gegen wart eines Lösungsmittels, wie Tetralin, Dodecan, Butylalkohol, begünstigt im hohen Masse die Bildung des Aldehyds. Besonders zweckmässig ist es, als Lösungsmittel den bei der Reaktion als Endprodukt entstehenden Alkohol zu verwenden, zum Beispiel bei der Verarbeitung von laurinsaurem Calcium, also den Laurinalkohol. Die Aufarbeitung des Reaktionsgemisches wird dadurch wesentlich vereinfacht.
Als Katalysatoren können sämt liche bekannte, einfache oder zusammen- gesetzte Hydrierungskatalysatoren für sich oder auf geeigneten Trägern niedergeschla gen, gegebenenfalls auch ohne vorherige Re duktion, verwendet werden, zum Beispiel Hupfer-, Nickel-, Kobalt-, Chrom-Katalysa- toren und deren Kombinationen.
Beispiel: 15 Gewichtsteile octylsaures Calcium und 15 Gewichtsteile ameisensaures Calcium wer den in 60 Gewichtsteilen Laurinalkohol un ter mässigem Erwärmen gelöst. Das Gemisch versetzt man mit einem Kupferkatalysator (der zum Beispiel durch Niederschlagen von Kupferkarbonat auf Kieselgur, Auswaschen, Trocknen und feines Verreiben dargestellt wurde) in solcher Menge, dass 1,6/o Kupfer vom Gewicht des octylsauren Calciums vor handen sind.
Man bringt dann das Gemisch in ein geschlossenes Reaktionsgefäss und presst Wasserstoff bis zu einem Druck von 110 Atm. ein. Man heizt allmählich auf <B>350',</B> wobei der Druck auf zirka 229 Atm. steigt und erhält eine Stunde auf dieser Tem peratur. Man lässt dann erkalten und bläst den Wasserstoffüberdruck ab. Als Reaktions- produkt erhält man Octylalkoho1, der ge gebenenfalls durch Destillation von dem als Lösungsmittel dienenden Laurinalkohol abgetrennt werden kann.
Process for the production of primary alcohols. It is known to produce the aldehydes of the fatty acid series by heating a mixture of calcium salts of fatty acids with calcium formate. It is also known to convert aldehydes into the corresponding primary alcohols by catalytic reduction with hydrogen.
It has now been found that the conversion of the calcium salts of the higher fatty acids and of the formic acid on the one hand and the catalytic hydrogenation of the aldehydes of the fatty series on the other hand can be accomplished in a very simple and advantageous manner in one work process and that primary alcohols are very high Obtained from prey and great purity. The first-mentioned reaction is promoted and brought to full completion by the fact that the aldehydes are removed from the reaction mixture by the catalytic reduction to the alcohols that is taking place at the same time, and the equilibrium of the aldehyde-forming reaction is continuously disturbed as a result.
This makes it possible to carry out the aldehyde formation under milder conditions and much more completely than is possible when carried out separately. According to the new process, one can get from the calcium salt of lauric acid via the lauric aldehyde to the lauric alcohol, from the stearic acid calcium via the stearic aldehyde to the stearic alcohol, etc. The method is carried out at increased pressure.
The temperature is suitably kept between 150 and 400 ° C. The presence of a solvent such as tetralin, dodecane, butyl alcohol, favors the formation of the aldehyde to a large extent. It is particularly expedient to use the alcohol formed as the end product during the reaction, for example when processing calcium laurate, i.e. lauric alcohol, as the solvent. This considerably simplifies the work-up of the reaction mixture.
All known, simple or composite hydrogenation catalysts can be used as catalysts, either alone or deposited on suitable supports, optionally also without prior reduction, for example Hupfer, nickel, cobalt, chromium catalysts and their Combinations.
Example: 15 parts by weight of calcium octylate and 15 parts by weight of calcium formate who are dissolved in 60 parts by weight of lauric alcohol under moderate heating. The mixture is mixed with a copper catalyst (which was prepared, for example, by depositing copper carbonate on kieselguhr, washing, drying and fine grinding) in such an amount that 1.6 / o copper of the weight of the calcium octylate is present.
The mixture is then placed in a closed reaction vessel and hydrogen is pressed up to a pressure of 110 atm. one. You gradually heat up to <B> 350 ', </B> with the pressure increasing to about 229 Atm. rises and maintains this temperature for an hour. It is then allowed to cool and the excess hydrogen pressure is blown off. The reaction product obtained is octyl alcohol, which, if necessary, can be separated from the lauric alcohol used as solvent by distillation.
