Abstract

La invencion se refiere a un metodo para producir 3-ciano-3,5,5-trimetilciclohexanona (nitrilo de isoforona) al hacer reaccionar isoforona con cianuro de hidrogeno en presencia de una base como un catalizador. Un acido sulfonico especial o un acido carboxilico especial se agrega al producto de nitrilo de isoforona crudo resultante el cual es destilado posteriormente. La invencion se refiere ademas al uso de un acido sulfonico especial o un acido carboxilico especial como un agente de neutralizacion antes de la destilacion de un producto de nitrilo de isoforona crudo que se obtiene al hacer reaccionar isoforona con cianuro de hidrogeno en presencia de una base como un catalizador a fin de evitar precipitaciones durante la neutralizacion de la base utilizada como un catalizador con acido.
