    Abstract: Procedimiento para separar iones metálico alcalinos de alcoxilados que contienen iones metálico alcalinos, que comprende: a) dilución del alcoxilado que contiene metal alcalino con un solvente inerte, b) tratamiento de la solución de alcoxilado que contiene metal alcalino con cambiador de cationes, para obtener una solución que contenga menos de 5 ppm de iones metálico alcalino, c) eliminación del solvente de la solución esencialmente libre de metal alcalino, para obtener un alcoxilado que contenga menos de 5 ppm de iones metálico alcalinos y menos de 1 000 ppm de solvente, siendo el procedimiento uno que comprende una regeneración del cambiador de cationes que consta de las siguientes etapas: d1) eliminación de la solución de alcoxilado a partir del cambiador de cationes y elución del cambiador de cationes con un solvente inerte, d2) elución, si es necesario, del cambiador de cationes con agua desmineralizada, d3) regeneración de la resina cambiadora de cationes con un ácido, d4) relavadode la resina cambiadora de cationes con agua desmineralizada, d5) elución del agua que se encuentra en la resina cambiadora de iones con un solvente inerte, y d6) si es necesario, cargar el cambiador de cationes con el solvente inerte deseado para el tratamiento con el cambiador de cationes, eliminando en la etapa d1) la solución de alcoxilado del cambiador de cationes, presionándolo con un gas inerte.
