Abstract
La presente invención se refiere a un procedimiento para producir metacroleina por oxidación catalítica de isobutileno y un procedimiento para producir metacroleina y ácido metacrílico mediante una oxidación catalítica de dos etapas de isobutileno, en donde la primera etapa produce principalmente metacroleina y la segunda etapa produce principalmente ácido metacrílico mediante oxidación de la metacroleina, el procedimiento utiliza una o más corrientes de recirculación hacia cualesquiera o ambas etapas, ambas etapas funcionan en corrientes de alimentación que contienen oxígeno y un gas diluyente inerte; la mejora consiste de utilizar uno o más gases diluyentes esencialmente anhídridos y esencialmente inertes como la alimentación de gas diluyente esencialmente inerte adicionada en la priemra etapa, teniendo la alimentación de gas diluyente esencialmente anhidra y esencialmente inerte adicionada una capacidad termica compuesta de por lo menos aproximadamente 6.5 calorías/gramo-mol (gradoslmente anhidros y esencialmente inertes como el gas diluyente alimentado a la segunda etapa, teniendo el diluyente esencialmente anhidro y esencialmente inerte adicionado, una capacidad termica compuesta de por lo menos aproximadamente 6.5 calorías/gramo-mol (oC).
