PROCEDIMIENTO PARA PREPARAR POLIAMIDAS Y POLIISOCIANATOS
SE PRESENTA UN PROCESO MEJORADO PARA LA PREPARACION DE UNA MEZCLA DE POLIAMINA DERIVADA MEDIANTE LA REACCION DE ANILINA CON UN FORMALDEHIDO ANTE LA PRESENCIA DE UN CATALIZADOR ACIDO, EN DONDE LA MEJORA CONSISTE EN REDUCIR SUAVEMENTE LA MEZCLA DE POLIAMINA MEDIANTE UN PROCESO QUE CONSISTE EN HIDROGEN...

| description | SE PRESENTA UN PROCESO MEJORADO PARA LA PREPARACION DE UNA MEZCLA DE POLIAMINA DERIVADA MEDIANTE LA REACCION DE ANILINA CON UN FORMALDEHIDO ANTE LA PRESENCIA DE UN CATALIZADOR ACIDO, EN DONDE LA MEJORA CONSISTE EN REDUCIR SUAVEMENTE LA MEZCLA DE POLIAMINA MEDIANTE UN PROCESO QUE CONSISTE EN HIDROGENAR CATALITICA O QUIMICAMENTE LA MEZCLA DE POLIAMINA ANTE LA PRESENCIA DE UN CATALIZADOR METALICO.
Disclosed herein is an improved process for preparing a polyamine mixture derived by reacting aniline with formaldehyde in the presence of an acid catalyst the improvement comprising mildly reducing the polyamine mixture by a process step comprising catalytically or chemically hydrogenating the polyamine mixture in the presence of a metal catalyst. |
