Silicalite Membrane for Separation of Acetic Acid / Water Mixture

Abstract
The polycrystalline silicalite membrane was prepared on a porous sintered stainless steel support and its pervaporation performance was investigated using an acetic acid / water mixture as a feed. The silicalite membrane selectively permeates acetic acid in the concentration of the feed acetic acid in the region of 5 to 40 vol%.
