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