Abstract

SE PRESENTA UN PROCESO PARA LA PURIFICACION DEL METACRILATO EN BRUTO OBTENIDO MEDIANTE LA REACCION DE ACETOCIANHIDRINA CON UN EXCESO DE ACIDO SULFURICO CONCENTRADO PARA FORMAR SULFATO DE METACRILAMIDO. ENTONCES SE LLEVA A CABO UNA REACCION DE TRANSPOSICION A ALTAS TEMPERATURAS PARA OBTENER SULFATO DE METACRILAMIDO; POSTERIORMENTE SE LLEVA A CABO LA ESTERIFICACION DEL METACRILAMIDO EN UNA SOLUCION DE ACIDO SULFURICO DILUIDO CON AGUA Y UTILIZANDO METANOL EN EXCESO; LAVANDO EL METILMETACRILATO EN BRUTO Y EFECTUANDO LA SUBSECUENTE DESTILACION; EL PROCESO SE CARACTERIZA EN QUE EL LAVADO SE LLEVA A CABO CON AMONIO DILUIDO, O AMINOS, Y AL MENOS UN AGENTE OXIDANTE OPERANDO EN LA PRESENCIA DE INHIBIDORES.
