| 141 | Phosphorylated cellulose ester membrane for use in separation or concentration of substances | US469281 | 1974-05-13 | US3962212A | 1976-06-08 | Takezo Sano; Takatoshi Shimomura |
| 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. | ||||||

| Enzymes are fixed to cellulose containing 5 to 25% lignin to form an enzyme-cellulose complex by a process involving treating cellulose pieces with an alkaline solution to remove lignin on the surface of the pieces, treating the resultant cellulose pieces with a sulfochlorinating or a chlorinating agent in an excess of pyridine until sulfur and/or chlorine is combined with the cellulose, washing the sulfur and/or chlorine-containing cellulose pieces and treating the pieces with an aqueous enzyme solution to attach enzymes thereto. A very important application is preparation of a rennet-cellulose complex and using the complex for coagulating milk in making cheese. | ||||||

| This invention deals with new phosphorus containing polymeric esters having pendent groups therein of the formula
OBTAINED BY THE REACTION OF A POLYMER HAVING AT LEAST 2 AND PREFERABLY AT LEAST 4 HYDROXY GROUPS THEREIN WITH A PHOSPHORUSHALOGEN COMPOUND OF THE FORMULA XP(O) (ORCX CXR'')2 wherein: R represents a divalent hydrocarbon radical containing 1-20 carbon atoms; R'' represents X, hydrogen or R''''; R'''' represents a monovalent hydrocarbon radical containing 1-20 carbon atoms; and X represents chlorine or bromine. Somewhat related polymers are also disclosed as derived by the reaction of WHEREIN Q'' is an organic moiety, n'' has a value of at least one, n'''' is one or two, R'''''' represents hydrogen or a monovalent hydrocarbon group of 1-20 carbon atoms, and the other symbols have the same meaning as defined above. Also disclosed are the reaction products of the phosphite compound HOP(ORCX CXR'')2 with an aldehyde and an organic nitrogen compound having one or two hydrogen atoms on the nitrogen, or with a compound having an ethylenic group therein. These new ester polymers and compounds are useful particularly as fire retardants, agricultural chemicals, fuel additives, plasticizers, monomers and intermediates for the synthesis of other useful derivatives. |
