ABSTRACT Cellulose acetate membranes, demonstrating good resistance to ketone and possessing the ability to separate ketone dewaxing solvent from dewaxed oil are described. They are prepared by using a carefully selected nonaqueous solvent process. The cellulose acetate membrane is cast, gelled and annealed in an entirely organic solvent system, preferably selected according to solubility parameter considerations. After casting, but before gelling, the more volatile of the two solvents is partially evaporated. The solvents used are such that no solvent exchange process is necessary to prepare the cellulose acetate membrane for use in ketone/oil separation procedures. Alternatively, the solvents are selected so that a solvent exchange process that does not weaken the membrane may be employed.
