ABSTRACT:
A novel phosphorylated cellulose ester membrane containing 0.1 to 10% of phosphorus and having a selective permeability. This permselective phosphorylated cellulose ester membrane consists essentially of a phosphorylated cellulose ester obtained by reacting a phosphorylating reagent such as phosphorus oxychloride with a lower aliphatic acid ester of cellulose, which has a reactive hydroxyl group, in an organic solvent, and then hydrolyzing the resulting ester. The membrane can be used widely in separating materials by processes such as reverse osmosis, ultrafiltration, dialysis, electrodialysis, and the like.
