Abstract
Procedimiento para la obtención continua de cetonas insaturadas de la fórmula general I en la cual puede significar la línea discontinua un enlace de C-C adicional, R1 significa un grupo alquilo ramificado o no ramificado con 1 a 4 átomos de carbono, y R2 significa un resto hidrocarburo alifático saturado o insaturado, ramificado o no ramificado, en caso dado substituido por grupos metoxi, con 1 a 37 átomos de carbono, un grupo cicloalquilo con 4 a 12 átomos de carbono o un grupo cicloalquilo con 5 a 30 átomos de carbono, mediante reacción de un alcohol insaturado de la fórmula general II en la cual tienen R1 y R2 el significado anteriormente indicado, con un éster alquílico del ácido acetacético de la fórmula general III en la cual significa R3 un grupo alquilo ramificado o no ramificado con 1 a 5 átomos de carbono, en presencia de compuestos de aluminio orgánicos como catalizador, caracterizado porque A.se hacen reaccionar el alcohol insaturado de la fórmula II con el éster alquílico del ácido acetacético de la fórmula III sobre las piezas agregadas (16) de una columna de fraccionamiento (4) para dar el acetoacetato del alcohol insaturado y se separa el alcohol, que se forma en este caso, de la fórmula IV con la corriente de cabeza (5) de la columna de fraccionamiento, y B.se redispone el acetoacetato formado del alcohol de la fórmula II en la parte inferior de la columna de fraccionamiento y/o en la cola (20) de la columna de fraccionamiento en presencia del compuesto de aluminio orgánico en la cetona insaturada de la fórmula I, llegando en este caso el dióxido de carbono, que se forma en este caso, a través de la columna de fraccionamiento (4) a la corriente de cabeza (5) y se separa la cetona insaturada formada de la fórmula general I a través de la cola (20) de la columna de fraccionamiento.
