Abstract
SE REFIERE A UN PROCEDIMIENTO PARA EL TRATAMIENTO DE AGUAS MADRE QUE SE OBTIENEN EN LA FABRICACION DE ACIDO ADIPICO MEDIANTE OXIDACION DE CICLOHEXANOL Y/O CILCLOHEXANONA O DE SUS MEZCLAS CON ACIDO NITRICO. EL ACIDO NITRICO ES DESTILADO, COMO AZEOTROPO, CON AGUA. LA MASA FUNDIDA, QUE SE OBTIENE, ES CALENTADA HASTA 130 A. LA SOLUCION ACUOSA ES TRATADA CON UN INTERCAMBIADOR DE CATIONES, EVAPORANDOSE A CONTINUACION EL AGUA. LA MASA FUNDIDA DE ACIDO DICARBOXILICO ES CALENTADA HASTA UNA TEMPERATURA DE 200 CION UNA MEZCLA DE ACIDO DICARBOXILICO.
