Abstract

LA PRESENTE INVENCION TRATA UN PROCESO PARA LA PREPARACION DE 3-CIANO-3, 5, 5''-TRIMETIL-1-CICLOHEXANORA POR MEDIO DE LA REACCION DE ISOFORONA CON UN CIANURO ALKALINO. LA REACCION ES REALIZADA PARTIENDO DE CANTIDADES IGUALES DE ISOFORONA Y DE CIANURO DISUELTOS EN UNA SOLUCION HOMOGENEA ACUOSO/ORGONICO A UNA TEMPERATURA COMPRENDIDA ENTRE 20 C, Y LA TEMPERATURA DE REFLUJO MANTENIENDO UN PH ENTRE 14 Y 8 POR MEDIOS DE LA ADICION GRADUAL DE UN ACIDO INORGANICO DURANTE LA REACCION.
