  Verfahren zur Herstellung von   Butanol- (1)-on- (3).

   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.

   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.

 

Claims (1)

2. Abänderung des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, dass man an Stelle von Vinylacetylen Buten- (1) -on- (3) als Ausgangsstoff verwendet und nach erfolgter Umsetzung das gebildete Butanol- (1) -on- (3) der weiteren Einwirkung des Katalysators, vorzugsweise durch Neutralisation oder Extraktion des Umsetzungsgemisches entzieht. 2. Modification of the method according to claim 1, characterized in that instead of vinylacetylene butene- (1) -one- (3) is used as the starting material and after the reaction has taken place the butanol- (1) -one- (3) formed removes further action of the catalyst, preferably by neutralization or extraction of the reaction mixture.
