Abstract
Procedimiento para la purificación de emulsionantes iónicos, del tipo de los productos de adición de óxidos de alquileno a compuestos que contienen grupos hidroxilo, carboxilo o carbonamida, de las impurezas que se forman durante su proceso de obtención, caracterizado porque las mezclas de reacción se disuelven en disolventes orgánicos, no miscibles con agua, se tratan con agua, se separa la capa acuosa y, en caso dado, los emulsionantes se aíslan retirando el disolvente orgánico.
