Process for isolating mesophase pitches.

摘要

A PITCH isotropic CONTAINING mesogens is combined with a solvent and undergoes a supercritical OR DENSE PHASE AND ARE mesogenic separate phase. In one aspect, THE PITCH isotropic CONTAINING mesogens is combined with a solvent to dissolve the mesogens, MIXTURE FLOW INGRESS TO EXTRACT ELEMENTS indissoluble AND mesogenic SEPARATE PHASE USING THE SAME SOLVENT UNDER A DENSE PHASE or under supercritical conditions PRESSURE AND TEMPERATURE. CONDITIONS OF PHASE SEPARATION mesogens are such that are recovered as mesophase.
