Abstract

Procedimiento para la extracción continua de partículas de poliamida, con un agente de extracción acuoso, en una columna de extracción esencialmente vertical, caracterizado porque se emplea una columna de extracción dividida en dos zonas, y se lleva a cabo, en la primera zona, una extracción con una disolución acuosa de "caprolactama al 15 hasta 40 % en peso, en recirculación, y después, en la segunda zona, una extracción con agua en contracorriente, siendo el diámetro de la columna de extracción en la primera zona mayor que el de la segunda zona, y situándose una barrera de ujo en la transición entre la primera y segunda zonas.
