Abstract

UN PROCESO CONTINUO PARA LA PRODUCCION DE OXAMIDA SE BASA EN LA OXIDACION CATALITICO DE CIANURO DE HIDROGENO CON OXIGENO O AIRE CON UN FUERTE EXCESO EN UNA SOLUCION DE NITRATO DE COBRE EN HIDROACIDO ACETICO. EL PROCESO SE REALIZA EN UN REACTOR TUBULAR VERTICAL , CON RECICLADO CONTINUO DE PARTE DE LA SUSPENSION DE OXAMIDAS DESDE EL FONDO A LA PARTE SUPERIOR DEL REACTOR.
