Abstract
PROCEDIMIENTO PARA LA OBTENCION DE IMIDAS CICLICAS.CONSISTE EN LA NITROGENACION DE HIDROCARBUROS PONIENDOLOS EN CONTACTO CON AMONIACO O UNA AMINA PRIMARIA Y OXIGENO MOLECULAR O UN GAS QUE CONTIENE OXIGENO EN FASE DE VAPOR, A TEMPERATURA ELEVADA, ENTRE 250JC Y 600JC, EN PRESENCIA DE UN CATALIZADOR DE OXIDACION, Y EN RECUPERAR EL PRODUCTO DE IMIDA CICLICA. LOS HIDROCARBUROS SE SELECCIONAN ENTRE ALCANOS, ALQUENOS, ALCADIENOS, ARILOS, ARILOS SUSTITUIDOS CON ALCOHILO E HIDROCARBUROS OXIGENADOS. EL CATALIZADOR DE OXIDACION CONTIENE OXIDOS DE METALES DE VALENCIA VARIABLE,TALES COMO TITANIO, CIRCONIO, NIOBIO, TANTALO, HIERRO, ALUMINIO, PLATINO, TIERRAS RARAS, METALES ALCALINOS Y ALCALINOTERREOS, Y SIMILARES; CATALIZADO RES ADECUADOS SON, TAMBIEN, LOS MOLIBDATOS DE ANTIMONIO, DE VANADILO Y DE BISMUTO, LOS FOSFOMOLIBDATOS, ANTIMONIATOS DE HIERRO Y SEMEJANTES. LA RELACION MOLAR DE AGENTE NITROGENANTE E HIDROCARBURO ES, AL MENOS, 0,5:1, LA RELACION MOLAR DE OXIGENO A HIDROCARBURO ES, AL MENOS, 2:1 A 30:1.
