Abstract
Se describen esteroles de las fracciones neutras de resina de tallol que se aíslan y purifican mediante un proceso de una extraccion de líquido-líquidodonde la corriente de extraccion de hidrocarburos se lava con una solucion de metanol acuosa para eliminar las impurezas solubles en metanol. Después deseparar las fases hidrocarbonada y acuosa, se agrega agua a la fase hidrocarbonada para facilitar la cristalizacion de los esteroles.Sterols of tallol resin neutral fractions that are isolated and purified by a liquid-liquid extraction process are described where the hydrocarbon extraction stream is washed with an aqueous methanol solution to remove methanol soluble impurities. After the hydrocarbon and aqueous phases are removed, water is added to the hydrocarbon phase to facilitate the crystallization of the sterols.
