Abstract

Un procedimiento para preparar compuestos ceto alfa,beta-insaturados por medio de la condensacion aldolica, catalizada con una base, de aldehidos y/ocetonas C1-15, en el que los aldehidos y/o las cetonas reaccionan con una solucion catalítica acuosa en una reaccion adiabática y la mezcla de reaccionobtenida de este modo se somete a una destilacion rápida. Este procedimiento para la condensacion de compuestos ceto para formar compuestos ceto alfa,beta-insaturados produce menos problemas ambiental es y es más economico que los procedimientos conocidos. El procedimiento descrito ofrece notables ventajas sobrelos procedimientos conocidos en la literatura: como resultado de las condiciones adiabáticas de la reaccion, el calor de reaccion en la me zcla de reaccion.Esto es utilizado en la destilacion rápida para evaporar el producto superior, o sea el agua y el material de partida sin reaccionar. Las pérdidas de calor delproceso se minimizan. Comparado con el procedimiento descrito en la patent e europea EP 0 634 994 B1, el procedimiento descrito más arriba tiene,adicionalmente, las siguientes ventajas: la mezcla de reaccion está sometida a las tensiones térmica y química en presencia de la solucion catalítica alcalinapor un tiempo signific ativamente menor que en una destilacion fraccionada. Como resultado, se forma una cantidad menor de ácido carboxílico por la reaccion deCannizzaro. Esto significa un rendimiento mayor en producto. Dada la menor cantidad de ácido carboxílico, que se p resenta como sal en la solucion catalítica,que debe ser descargada, la pérdida de catalizador es menor. Más aun, es ventajoso usar parte del agua destilada para lavar el producto en bruto. Comparado conlos procedimientos convencionales en los que el agua de reaccion queda en la solucion catalítica y se descarga en ella, el procedimiento descrito más arribatiene la ventaja adicional de un menor consumo de catalizador.
