Abstract

La presente invención se refiere a un proceso mejorado para preparar triacetonamina. El proceso implica realizar una etapa de absorción en donde la acetona presente en el producto crudo se elimina de la triacetonamina por destilación y después en forma gaseosa se absorbe en contracorriente en acetona líquida fresca. La corriente de acetona así obtenida se convierte después además en triacetonamina. Este proceso permite una reutilización más eficiente desde el punto de vista energético de los reactivos sin reaccionar utilizados en la síntesis de triacetonamina y, por lo tanto, reduce en general tanto el uso de reactivos como el gasto energético.
