Abstract

Chemically and thermally resistant membranes suitable for the separation of low molecular weight substances from organic solvents were developed. Porous membranes from polyacrylonitrile and polyamideimide were optimized for this application. Cellulose ethers, like hydroxypropylmethyl-cellulose (HPMC) and polyether-block-polyamides, were used as selective coatings. Special attention was paid to the separation of edible oil/solvent mixtures. Composite membranes with 99% oil retention could be prepared with HPMC as selective layer.
