Abstract
LA INVENCION SE REFIERE A UN PROCESO PARA LA PREPARACION DE DIBENCILAMINA POR HIDROGENACION DE BENZALDEHIDO EN PRESENCIA DE AMONIACO Y UN CATALIZADOR CON PALADIO USANDO UNA PEQUEÑA CANTIDAD DE SOLVENTE O MEDIO DE DISPERSION. CON ESTE PROCESO LA DIBENCILAMINA PUEDE PREPARARSE CON ALTA SELECTIVIDAD EN UN TIEMPO DE REACCION RELATIVAMENTE CORTO Y CON CONVERSION COMPLETA DEL BENZALDEHIDO EN UN PROCESO PARTICULARMENTE ATRACTIVO DESDE UN PUNTO DE VISTA COMERCIAL. EN ESTE PROCESO SE UTILIZA PREFERENTEMENTE UN CATALIZADOR DE PALADIOCARBON.
