Abstract

SE DESCUBRE UN PROCESO PARA PRODUCIR METACRILATO DE METILO, EL CUAL COMPRENDE: (I) UN PASO DE REACCIONAR ACIDO PRUSICO Y ACETONA PARA FORMAR ACETONACIANHIDRINA; (II)UN PASO DE HIDRATAR LA ACETONACIANHIDRINA OBTENIDA EN EL PASO (I) PARA FORMAR AMIDO ACIDO (ALFA)-HIDROXIISOBUTIRICO; (III)UN PASO DE DESHIDRATAR EL AMIDO ACIDO (ALFA)-HIDROXIISOBUTIRICO OBTENIDO EN EL PASO (II) PARA FORMAR AMIDO ACIDO METACRILICO; (IV)UN PASO DE REACCIONAR EL AMIDO ACIDO METACRILICO OBTENIDO EN EL PASO (III) Y FORMATO METILO PARA FORMAR METACRILATO DE METILO Y FORMAMIDA; Y (V)UN PASO DE DESHIDRATAR FORMAMIDA SEPARADA DEL PRODUCTO OBTENIDO EN EL PASO (IV) PARA FORMAR ACIDO PRUSICO Y RECICLAR DICHO ACIDO PRUSICO COMO MATERIAL DE PARTIDA PARA EL PASO (I). EL PROCESO PRODUCE METACRILATO DE METILO CON GRAN SELECTIVIDAD SIN INDESEABLES SUB-PRODUCTOS TALES COMO SULFATO AMONICO.
