Abstract

UN PITCH ISOTROPICO QUE CONTIENE MESOGENOS SE COMBINA CON UN SOLVENTE Y SE SOMETE A UNA FASE DENSA O A CONDICIONES SUPERCRITICAS Y LOS MESOGENOS SON DE FASE SEPARADA. EN UN ASPECTO, EL PITCH ISOTROPICO QUE CONTIENE MESOGENOS SE FUNDE CON UN SOLVENTE PARA SOLUBILIZAR LOS MESOGENOS, LA MEZCLA DE FLUJO SE FILTRA PARA EXTRAER LOS ELEMENTOS INDISOLUBLES Y LOS MESOGENOS SE SEPARAN DE FASE UTILIZANDO EL MISMO SOLVENTE BAJO UNA FASE DENSA O BAJO CONDICIONES SUPERCRITICAS DE PRESION Y DE TEMPERATURA. LAS CONDICIONES DE LA SEPARACION DE FASE SON TALES QUE LOS MESOGENOS SE RECUPERAN COMO MESOFASE.
