| titleOfInvention | Process for the preparation of 2,5,6-trimethyl-cyclohex-2-en-1-on |
| abstract | a) gleichzeitig ein Mol Crotonaldehyd oder ein Mol einer Verbindung,ndie unter den Reaktionsbedingungen in Crotonaldehydnumgewandelt wird, etwa 5 bis 30 Mole Diethylketon und dienwässrige Lösung oder Suspension einer starken Base durch getrenntenZuleitungen oder zumindest teilweise in Form einesngeeigneten Gemisches kontinuierlich in einen gegebenenfallsnerhitzten Druckbehälter, der eine intensive Vermischung gewährleistet,nso zupumpt, daß b) die Reaktionstemperatur zwischen 150°C und 350°C liegt und dienmittlere Verweilzeit im Druckbehälter nur etwa 0,1 Sekundennbis 20 Minuten beträgt. Process for the preparation of 2,5,6-trimethyl-cyclohex-2-en-1-one by reacting diethyl ketone with crotonaldehyde or a compound which is converted into crotonaldehyde under the chosen reaction conditions in the presence of basic agents at elevated temperature, which is characterized in that one a) at the same time one mole of crotonaldehyde or one mole of a compound which is converted into crotonaldehyde under the reaction conditions, about 5 to 30 moles of diethyl ketone and the aqueous solution or suspension of a strong base by separate feed lines or at least partially in the form of a suitable mixture continuously into one if necessary heated pressure vessel, which ensures intensive mixing, pumped in such a way that b) the reaction temperature is between 150 ° C and 350 ° C and the average residence time in the pressure vessel is only about 0.1 seconds to 20 minutes. |
