Description
<Desc/Clms Page number 1>
Verfahren zur Herstellung von Butanol- (1)-on- (3).
EMI1.1
<Desc/Clms Page number 2>
Diese Ausführungsform ist nur eine beispielsweise ; statt Schwefelsäure können beliebige andere Säuren Verwendung finden, ebenso kann die Konzentration der Reaktionskomponenten und des Katalysators sowie Umsetzungstemperatur und-dauer beliebig abgeändert werden. Bei höherer Temperatur läuft die Reaktion in kürzerer Zeit mit geringerem Katalysatoraufwand ab.
Beispiel 3 : In dem Destillationskolben eines Flüssigkeits-Extraktionsapparates, der mit verdünnter Schwefelsäure beschickt ist, wird eine Mischung von 15 Gew.-Teilen Äther, 7 Gew.-Teilen Buten- (1) -on- (3) und 2 Gew.-Teilen Wasser eingebracht. Die Dämpfe der siedenden Mischung werden kondensiert, das Kondensat perlt durch die Schwefelsäure und fliesst in die Vorlage zurück. Dabei wird das mit dem Äther übergangene Buten- (1) -on- (3) durch die Schwefelsäure zum Teil hydratisiert.
Die Hydratisierungsprodukte werden vom Äther aufgenommen und sammeln sich im Destillationskolben an. Auf diese Weise gelingt es, Buten- (1) -on- (3) fast quantitativ in ein Hydratisierungsprodukt
EMI2.1
Butanol- (1)-on- (3) und Bis- [-oxobutyl]-äther besteht.
PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Butanol- (1) -on- (3) durch Wasseranlagerung an Vinylacetylen in Gegenwart von Katalysatoren, dadurch gekennzeichnet, dass man während der Umsetzung das Entweichen von Buten- (1) -on- (3) aus dem Reaktionsraum verhindert und nach erfolgter Umsetzung das gebildete Butanol- (1) -on- (3) der weiteren Einwirkung des Katalysators, vorzugsweise durch Neutralisation oder Extraktion des Umsetzungsgemisehes, entzieht.

Process for the preparation of butanol- (1) -one- (3).
EMI1.1
<Desc / Clms Page number 2>
This embodiment is just an example; Instead of sulfuric acid, any other acids can be used, and the concentration of the reaction components and the catalyst as well as the reaction temperature and duration can be changed as desired. At a higher temperature, the reaction takes place in a shorter time with less catalyst expenditure.
Example 3: In the distillation flask of a liquid extraction apparatus which is charged with dilute sulfuric acid, a mixture of 15 parts by weight of ether, 7 parts by weight of butene- (1) -one- (3) and 2 parts by weight Parts of water introduced. The vapors of the boiling mixture are condensed, the condensate bubbles through the sulfuric acid and flows back into the receiver. The buten- (1) -one- (3) passed over with the ether is partially hydrated by the sulfuric acid.
The hydration products are absorbed by the ether and collect in the still. In this way it is possible to convert butene- (1) -one- (3) almost quantitatively into a hydration product
EMI2.1
Butanol- (1) -one- (3) and bis- [-oxobutyl] -ether.
PATENT CLAIMS:
1. A process for the preparation of butanol- (1) -one- (3) by addition of water to vinyl acetylene in the presence of catalysts, characterized in that the escape of butene- (1) -one- (3) from the during the reaction Prevents the reaction space and, after the reaction has taken place, removes the butanol- (1) -one- (3) formed from further action by the catalyst, preferably by neutralization or extraction of the reaction mixture.
