Abstract
EL INVENTO SE REFIERE A UN NUEVOS PROCEDIMIENTO, QUE EVITA LA PRESENCIA DE ELEVADOS CONTENIDOS DE ALQUILENOXIDO Y DIOXANO CONTENIDO EN ALQUILENOXIDOS INFERIOR A 1 PPM Y EN DIOXANO 4 INFERIOR A 3 PPM. SE UTILIZA PARA OBTENER PRODUCTOS EMPLEADOS EN TOXICOLOGIA Y SE CARACTERIZA PORQUE SE EMPLEA UN CATALIZADOR PARA LA TRANSFORMACION DIRECTA DE ALCOHOLES GRASOS CON HIDROXIDO ALCALINO, QUE CONSISTE EN ALCOHOLATOS GRASOS.
