Description
Verfahren zur Herstellung von Acetoäthylalkohol Behandelt man t # 3-Butylenglykol in der Gasphase mit dehydrierenden Mitteln, so erhält man nach der Literatur Methyläthylketon.Process for the preparation of acetoethyl alcohol If one treats t # 3-Butylene glycol in the gas phase with dehydrating agents is obtained after Literature methyl ethyl ketone.
Es wurde nun gefunden, daB bei dem Arbeiten unter vermindertem Druck die Reaktion in anderer Richtung verläuft und als Hauptprodukt der Acetoäthylalkohol entsteht, der Verwendung z. B. als Zwischenprodukt für die Herstellung von Kunststoffen findet.It has now been found that when working under reduced pressure the reaction proceeds in the other direction and the main product is acetoethyl alcohol arises, the use z. B. as an intermediate product for the manufacture of plastics finds.
Beispiel Über einen Katalysator, der durch Auftragen von gefälltem basischem Kupfercarbonat mit Wasserglas auf einem Träger und darauffolgende Trocknung und Reduktion im Wasserstoffstrom bei etwa i So' erhalten wurde, leitet man einen Strom von t # 3-Butylen,-glykoldampf (l/41,-- pro Stunde und Liter Kontaktraum) bei Zoo bis 22o° und einem Quecksilberdruck von 25 mm. Die den Kontaktraum verlassenden Produkte werden kondensiert und enthalten neben Ausgangsmaterial, das dem ReaktionsprozeB im Kreislauf wieder zugeführt werden kann, in guter Ausbeute Acetoäthylall:ohol neben geringen Mengen von Nebenprodukten.Example of a catalyst that is produced by the application of precipitated basic copper carbonate with water glass on a support and subsequent drying and reduction in a stream of hydrogen at about i So ', one conducts one Stream of t # 3-butylene, -glycol vapor (l / 41, - per hour and liter of contact space) at zoo up to 22o ° and a mercury pressure of 25 mm. Those leaving the contact area Products are condensed and, in addition to starting material, they contain the reaction process can be fed back in the circuit, in good yield Acetoäthylall: ohol besides small amounts of by-products.
Zu ähnlichen Ergebnissen kommt man auch, nenn man Katalysatoren ohne Träger verwendet und bei Abwesenheit alkalisch wirkender Substanzen arbeitet.One also comes to similar results if one calls catalysts without Carrier used and works in the absence of alkaline substances.
