Abstract

LA INVENCION SE REFIERE A LA OBTENCION DE ACIDO GLIOXILICO. SE LLEGA A ELLO OXIDANDO UNA DISOLUCION ACUOSA DE GLIOXAL QUE TIENE UN PH INFERIOR A 1 CON OXIGENO MOLECULAR EN PRESENCIA DE MONOXIDO DE NITROGENO COMO CATALIZADOR. ESTE PROCEDIMIENTO PERMITE UNA TRANSFORMACION PRACTICAMENTE CUANTITATIVA DEL GLIOXAL DE SALIDA CON UN BUEN RENDIMIENTO EN ACIDO GLIOXILICO.
