Description
Verfuhren zur Darstellung eines Alkohols. Das Hauptpatent 164834 betrifft ein Ver fahren zur Darstellung eines Alkohols, wel= ches dadurch gekennzeichnet ist, dass man ein gemischtes Anhydrid zwischen Laurin- säure und Borsäure mit katalytisch ange regtem Wasserstoff behandelt.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Dodecyl- alkohols, welches dadurch gekennzeichnet ist, dass man ein gemischtes Anhydrid zwischen Laurinsäure und Kieselsäure, mit katalytisch angeregtem Wasserstoff behandelt.
Es hat sich auch hier als vorteilhaft er wiesen, die Reaktion, die man auch im kon tinuierlichen Arbeitsverfahren durchführen kann, durch Anwendung von stark aktiven Katalysatoren, sowie von höherem Druck und Wärme zu unterstützen. Man braucht zu der Reaktion nicht reines Wasserstoffgas zu verwenden, sondern kann auch Mischungen dieses Gases mit andern Gasen, wie Stick stoff, Kohlenoxyd und -dioxyd und dergleichen verwenden. Als Katalysatoren haben sich bewährt aktivierte Zink-, Silber-, Nickel-, Kupfer katalysatoren, Kupferchromit bezw. Nickel- chromit und andere mehr.
Die gegebenenfalls giftfesten Katalysatoren können in feinver teiltem Zustand oder auf Trägern wie Kiesel gur, Asbest und dergleichen niedergeschlagen verwendet werden.
Zweckmässig verwendet man natürlich die Ausgangsstoffe in vorgereinigtem Zustande, um Vergiftungen der Katalysatoren vorzu beugen.
Das Reaktionsprodukt lässt sich beispiels weise durch Destillation, gegebenenfalls unter Anwendung von Vakuum, von den Kataly satoren leicht trennen und kann so in sehr reiner Form erhalten werden. <I>Beispiel:</I> 300 Teile Laurinsäure-Kieselsäureanhydrid werden mit 30 Teilen Kupferkatalysator ver mengt und im Autoklaven bei 132 at Was serstoffanfangsdruck unter Rühren auf 250<B>0 0</B> erhitzt. Die einsetzende Reduktion gibt sich durch den Abfall des Wasserstoffdruckes alsbald zu erkennen. Wenn kein Wasserstoff mehr aufgenommen wird, kühlt man den Autoklaven ab, füllt das Produkt aus und befreit es vom Katalysator.
Durch Vakuum destillation kann der entstandene Dodecyl- alkohol noch weiter gereinigt werden.
Procedure to represent an alcohol. The main patent 164834 relates to a method for the preparation of an alcohol, which is characterized in that a mixed anhydride between lauric acid and boric acid is treated with catalytically excited hydrogen.
The subject of the present patent is a process for the production of a dodecyl alcohol, which is characterized in that a mixed anhydride between lauric acid and silica is treated with catalytically activated hydrogen.
Here, too, it has proven to be advantageous to support the reaction, which can also be carried out in a continuous process, by using highly active catalysts and by using higher pressure and heat. You do not need to use pure hydrogen gas for the reaction, but can also use mixtures of this gas with other gases such as nitrogen, carbon dioxide and carbon dioxide and the like. As catalysts, activated zinc, silver, nickel, copper catalysts, copper chromite respectively. Nickel chromite and others.
The optionally poison-resistant catalysts can be used in finely divided state or deposited on supports such as kieselguhr, asbestos and the like.
It is of course advisable to use the raw materials in a pre-cleaned state in order to prevent the catalytic converters from being poisoned.
The reaction product can be easily separated from the catalysts, for example, by distillation, if necessary using a vacuum, and can thus be obtained in a very pure form. <I> Example: </I> 300 parts of lauric acid-silicic acid anhydride are mixed with 30 parts of copper catalyst and heated to 250 <B> 0 0 </B> in an autoclave at 132 atm. Hydrogen initial pressure with stirring. The onset of reduction can be recognized immediately by the drop in hydrogen pressure. When no more hydrogen is absorbed, the autoclave is cooled, the product is poured out and the catalyst is removed from it.
The dodecyl alcohol produced can be purified further by vacuum distillation.
