Separation of the unsaturated fractions of industrial cuts, like ethane-ethylene or benzene-cyclohexane, is a very important task for petrochemical industry. The conventional separation methods industrially are very expensive1,2 and the development of new separation methods to circumvent these disadvantages is of high interest.

In this work, the preparations of pervaporation (PV) aromatic selective mixed matrix membranes for toluene-heptane separation were carried outstarting from poly(vinylchloride) (PVC), a low cost polymer. Indeed PVC is a polar polymer endowed with a high affinity for aromatic solvents. Thus mixed matrix PVC membranes were studied to determine if it was possible to obtain interesting separation properties from this simple and cheap polymer. We report the results obtained by the incorporation of clays as inorganic fillers 3. Hence, PVC based mixed matrix membranes were prepared with HDL(NiFeCO3) particles. It was found that...
