Abstract
1.- Un proceso continuo para la recuperación de caprolactama a partir de un producto de caprolactama acuoso; dicho producto de caprolactama acuoso contiene (i) caprolactama, (ii) impurezas, y (iii) agua, dicho proceso comprende:- Adición de hidróxido de álcali al producto de caprolactama acuoso, en una cantidad no mayor de 100 mmol de hidróxido de álcali por kg de caprolactama;- Reacción de por lo menos parte del hidróxido de álcali adicionado, para formar caproato amino álcali, para obtener un producto de caprolactama rico en caproato; y- Destilación del producto de caprolactama rico en caproato, a presión reducida.2.- El proceso de acuerdo a la reivindicación 1, en donde el proceso comprende la reacción de la menos 50% mol del hidróxido de álcali adicionado, para formar un caproato amino álcali antes de dicha destilación.
