Abstract
La presente invencion se refiere al uso de una composicion solida de oxidos mixtos de la formula (I): 2<-a<-14, 0.1<-b<-6, 0<-c<-12, 0<-d<-6, 0<-e<-15;, x es la cantidad de oxigeno enlazada en los otros elementos y depende de sus estados de oxidacion, en la elaboracion de ácido acrílico por oxidacion de acroleína, reaccionado dicha composicion solida con acroleína de acuerdo con la reaccion de oxidacion-reduccion: SOLIDOoxidado+ACROLEINA -->SOLIDOreducido + ACIDO ACRILICO; para elaborar ácido acrílico, se hace pasar una mezcla gaseosa de acroleína y de vapor de agua y, si es apropiado, de un gas inerte, sobre una composicion solida de la formula (I), para conducir la reaccion de oxidacion-reduccion (1) trabajando a una temperatura de 200 a 500 degree C, a una presion de 1.01 x 104 a 1.01 x 106 Pa (0.1 a 10 atmosferas), y con un tiempo de permanencia de 0.01 segundo a 90 segundos, en ausencia de oxígeno molecular.
