Description
Verfahren zur Anlagerung von CO an organische Verbindungen in Gegenwart eines Natalysators und Wasserdampf. Es ist bereits bekannt, dass bei der Be handlung von organischen Verbindungen in der Dampfphase, insbesondere bei Anlage- rungsreaktionen, wie sie durch Einwirken von Alkoholen auf Kohlenoxyd herbeigeführt wer den, eine Anzahl von Katalysatoren sauren Charakters auf Trägern oder Absorbentien, wie Bimsstein, Silikagel und aktivierter Kohle, verteilt verwendet werden. Auf diese Weise ist zum Beispiel Methanol in Essig säure und Methylacetat umgewandelt worden.
Es wurde gefunden, dass Borhalogenver- bindungen flüchtiger Natur äusserst aktive Katalysatoren für diese Reaktionsform dar stellen und auch den Vorteil haben, sich leicht wiedergewinnen und wiederholt verwenden zu lassen.
Die vorliegendeErfindung bezieht sich auf ein Verfahren zur Anlagerung von CO an or ganische Verbindungen in Gegenwart von Wasser bei erhöhter Temperatur und Druck, dadurch gekennzeichnet, dass die Reaktionen in der Dampfphase in Gegenwart von min destens einer Borhalogenverbindung als Ka talysator mit kondensierender Wirkung, aus geführt werden. Beispiele für geeignete Ka talysatoren für vorliegendes Verfahren sind Borchloridjodid, -bromid und -fluorid einzeln oder zusammen angewandt.
Eine oder mehrere dieser Verbindungen können auch zusammen mit den entsprechenden Halogenwasserstoffen, insbesondere der HF, sowie der Säuren der Borhalogenide, angewandt werden, wie Di- hydroxyfluorborsäure,Borfluorwasserstoffsäure, ferner Mischungen von Fluorwasserstoff und Borsäure, wobei letztere zum Teil oder ganz dehydratisiert sein kann unter Bildung von BFs. Bei teilweiser Dehydratisierung mischt man mit Vorzug mit BFs . Borfluorid wird an sich vorgezogen.
Als Trägerstoffe lassen sich Tonerde, Kohlenstoff und aktivierte Kiesel säure verwenden, dies ist jedoch nicht we- sentlich. Die Trägerstoffe können Beschleu niger, wie gepulvertes Nickel oder Nickel- oxyde enthalten, indessen sind in) allgemeinen die Borhalogenide so aktiv, dass Beschleuniger nicht erforderlich sind.
Alkohole, z. B. Methanol, Äthanol, Pro- panol, die Butanole, Hexariol, Oktanol, 2,4- Dinietliylpetitanol-l, Ester, Alkyläther und Alkylhalogenide oder andere Verbindungen, die sich<B>unter</B> Bildung vors Alkoholen zer setzen lassen, werden leielit in der Dampf phase unter Verwendung der neuen Kataly satoren mit Kohlenstoffnionoxyd zur Reaktion gebracht; es bilden sich Säuren, Ester und dergleichen.
Es ist zweckmässig, dass Wasser dampf in den Reaktionsgasen vorhanden ist, wenn man eine Säure als Endprodukt erhalten will, insbesondere wenn ein Alkohol umge setzt wird.
Es ist zweckmässig, wenn der verwendete Druck iin allgemeinen zwischen 25-900 Atmosphären sich befindet, ein besonders vor teilhaftes Intervall wäre zwischen 350-700 Atmosphären. Das mit. Vorteil zti verwendende Temperaturintervall ist 200-300o C. Das Kohlensto$'monoxyd wird zweckmässig frei von Schwefel und Metallkarbonylverbindungen angewendet, obgleich inerte Gase wie Stick stoff sich ihm reit Vorteil beimischen lassen.
Beispiel: Eine gasförmige, 83% CO und je 5/'o Methanol, Wasserdampf und Wasserstoff ent haltende Mischung wird zusammen mit etwa 2 % BFa in eine Umwandlungskammer ein- geleitet, die aktivierte Knochenkohle enthält und geeignet ist,
gasförmige exothernie Re aktionen unter erhöhtem Druck auszufiihren. Die Reaktion wird bei etwa<B>3250</B> C unter einem Druck von etwa 700 Atmosphären durchgeführt. Bei der Kondensation erhält man eine gute, sich der quantitativen nähernde Ausbeute an Essigsäure und Metbylacetat zusammen mit kleinen Mengen anderer ali- phatischer Säuren und Ester.
Process for the addition of CO to organic compounds in the presence of a catalyst and water vapor. It is already known that in the treatment of organic compounds in the vapor phase, in particular in the case of attachment reactions such as those brought about by the action of alcohols on carbon oxide, a number of acidic catalysts on supports or absorbents such as pumice stone, silica gel and activated carbon, can be used in a distributed manner. In this way, for example, methanol has been converted into acetic acid and methyl acetate.
It has been found that boron-halogen compounds of a volatile nature are extremely active catalysts for this form of reaction and also have the advantage that they can be easily recovered and used repeatedly.
The present invention relates to a process for the addition of CO to organic compounds in the presence of water at elevated temperature and pressure, characterized in that the reactions are carried out in the vapor phase in the presence of at least one boron halogen compound as a catalyst with a condensing effect will. Examples of suitable catalysts for the present process are boron chloride iodide, bromide and fluoride used individually or together.
One or more of these compounds can also be used together with the corresponding hydrogen halides, in particular the HF, and the acids of the boron halides, such as dihydroxyfluoroboric acid, borofluoric acid, and also mixtures of hydrogen fluoride and boric acid, the latter can be partially or completely dehydrated under Formation of BFs. In the case of partial dehydration, preference is given to mixing with BFs. Boron fluoride is preferred per se.
Alumina, carbon and activated silicic acid can be used as carriers, but this is not essential. The carrier substances can contain accelerators such as powdered nickel or nickel oxides, but in general the boron halides are so active that accelerators are not required.
Alcohols e.g. B. methanol, ethanol, propanol, the butanols, hexariol, octanol, 2,4-dinietliylpetitanol-1, esters, alkyl ethers and alkyl halides or other compounds which can be decomposed with formation before alcohols , are made to react in the vapor phase using the new catalysts with carbon nonion oxide; acids, esters and the like are formed.
It is useful that water vapor is present in the reaction gases if you want to obtain an acid as the end product, especially if an alcohol is converted.
It is practical if the pressure used is generally between 25-900 atmospheres, a particularly advantageous interval would be between 350-700 atmospheres. That with. The advantage of the temperature range used is 200-300 ° C. The carbon monoxide is best used free of sulfur and metal carbonyl compounds, although inert gases such as nitrogen can be mixed with it.
Example: A gaseous mixture containing 83% CO and 5 / o each of methanol, water vapor and hydrogen is introduced into a conversion chamber together with about 2% BFa, which contains activated bone char and is suitable
perform gaseous exothermic reactions under increased pressure. The reaction is carried out at about 3250 C under a pressure of about 700 atmospheres. The condensation gives a good yield of acetic acid and methyl acetate that approximates the quantitative one, together with small amounts of other aliphatic acids and esters.
