Abstract
Se describe un proceso para preparar un producto de reacción que contienemetilendifenilamina, que comprende hacer reaccionar anilina con unaldehído, en la presencia de un nivel bajo de un ácido, en donde el nivelde ácido se reduce antes de digerir la mezcla de reacción a una altatemperatura, que es suficiente para efectuar una reordenación de losintermediarios, para producir un producto de reacción que contienemetilendifenilaminas y niveles bajos de impurezas.
