Abstract

LO DESCRITO ES UN METODO PARA PRODUCIR METACROLEINA, EL CUAL CONSISTE EN SOMETER AL MENOS UN ELEMENTO SELECCIONADO DEL GRUPO QUE CONSTA DE ISOBUTILENO Y TERC-BUTANOL A OXIDACION CATALITICA EN FASE GASEOSA CON UN GAS QUE CONTIENE OXIGENO MOLECULAR EN PRESENCIA DE UNA COMPOSICION CATALIZADORA DE OXIDO REPRESENTADA POR LA FORMULA MO{SUB,12}BI{SUB,A}CE{SUB,B}K{SUB,C}FE{SUB,D}A{SUB,E}B{SUB,F}O{SUB,G}, EN DONDE A ES UNICAMENTE CO, O UNA MEZCLA DE CO Y MG EN DONDE LA PROPORCION ATOMICA DE MG PARA CO NO ES MAS DE 0,7, B ES RB, CS O UNA MEZCLA DE LOS MISMOS, Y A, B, C, D, E, F Y G SON, RESPECTIVAMENTE, LAS PROPORCIONES ATOMICAS ESPECIFICAS DE BI, CE, K, FE, A, B Y O, RELATIVAS A DOCE ATOMOS DE MO. MEDIANTE EL METODO DE LA PRESENTE INVENCION, ES POSIBLE PRODUCIR DE FORMA ESTABLE METACROLEINA EN ALTO RENDIMIENTO, UTILIZANDO UNA COMPOSICION CATALIZADORA DE OXIDO QUE TIENE UNA COMPOSICION ESTRUCTURAL RELATIVAMENTE SENCILLA Y POR ELLO PUEDE PREPARARSE FACILMENTE, Y LA CUAL TIENE NO SOLO UNA VIDA DE CATALIZADOR PROLONGADA DEBIDA A LA EXCELENTE ESTABILIDAD TERMICA Y RESISTENCIA A LA REDUCCION, SINO TAMBIEN EXCELENTE SELECTIVIDAD PARA METACROLEINA, EN DONDE LA COMPOSICION CATALIZADORA CONTIENE BI, CE, K Y FE EN CANTIDADES ESPECIFICAS Y EN UNA PROPORCION DE CANTIDAD RELATIVA ESPECIFICA, Y NO CONTIENE DICHOS ELEMENTOS QUE CAUSAN CONTAMINACION AMBIENTAL Y PROBLEMAS DE TOXICIDAD, Y ADEMAS NO REQUIERE EL USO, COMO MATERIAS PRIMAS PARA LA PREPARACION DEL MISMO, COMPOSICIONES QUE TIENEN BAJA SOLUBILIDAD EN AGUA, COMO COMPOSICIONES DE W, SB Y NB, LAS CUALES SE HAN UTILIZADO FRECUENTEMENTE CON EL FIN DE LOGRAR RENDIMIENTOS CATALITICOS DESEADOS, AUNQUE LA UTILIZACION DE LAS CUALES TIENE DESVENTAJAS DEBIDO A LAS DIFICULTADES EN LA OBTENCION DE COMPOSICIONES CATALIZADORAS UNIFORMES.
