Abstract

PROCEDIMIENTO PARA DESCONTAMINAR CIANHIDRINAS Y/O SOLUCIONES ACUOSAS QUE CONTIENEN NITRILOS. LA INVENCION CONCIERNE A UN PROCEDIMIENTO PARA LA DESCONTAMINACION DE CIANHIDRINAS, ESPECIALMENTE GLICOLNITRILO, Y/O SOLUCIONES ACUOSAS QUE CONTIENEN NITRILOS, QUE CONTIENEN ADICIONALMENTE CATALIZADORES DE DESCOMPOSICION PARA COMPUESTOS DE PEROXIDOS, ESPECIALMENTE COMPUESTOS DE MANGANESO, MEDIANTE LA PERHIDROLISIS DE LOS COMPUESTOS CIANICOS A UNAS TEMPERATURAS DE 5 A 80 (GRADOS) C Y VALORES DE PH DE 8 A 12, CON UNO O VARIOS COMPUESTOS DE PEROXIDO DE LA SERIE DE LOS PERCARBONATOS ALCALINOS Y PERBORATOS DE METALES ALCALINOS Y ALCALINO-TERREOS ASI COMO PEROXIDOS ALCALINO-TERREOS, EN DONDE LOS COMPUESTOS DE PEROXIDOS MENCIONADOS SE AÑADEN COMO TALES A LA SOLUCION A DESCONTAMINAR O SE FORMAN IN-SITU EN LA SOLUCION A DESCONTAMINAR. EL PROCEDIMIENTO DE LA INVENCION ES MAS EFECTIVO Y ECONOMICO QUE EL PROCEDIMIENTO CONOCIDO ANTERIOR BAJO LA APLICACION DE PEROXIDO DE HIDROGENO.
