Abstract

SE REVELA UN PROCESO PARA RECUPERAR HIDROXIPIVALILO HIDROXIPIVALATO (HPHP) PURIFICADO DE UN MATERIAL CRUDO QUE CONTIENE HPHP CON RESIDUOS INORGANICOS DEL CATALIZADOR E IMPUREZAS CON PUNTOS DE EBULLICION BAJOS Y ALTOS (RESPECTO AL PUNTO DE EBULLICION DE HPHP). EL PROCESO DE PURIFICACION COMPRENDE DOS ZONAS DE DESTILACION, UNA DONDE SE SEPARAN LAS IMPUREZAS INORGANICAS Y DE ALTA EBULLICION Y OTRA DONDE SE SEPARAN LAS IMPUREZAS DE ALTA Y DE BAJA EBULLICION.
