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.
