| titleOfInvention | Production of granular porous chitosan |
| abstract | PURPOSE: To obtain porous granular chitosan having uniform particle size, and uniform fine pores on the surface of the sphere or the broken surface, and suitable as a stationary phase of chromatography, by preparing a concentrated chitosan solution from a chitosan having low molecular weight, and dripping the solution into a basic solution to effect the coagulation of the chitosan solution. n CONSTITUTION: A low-molecular weight chitosan having an average molecular weight of 10,000W230,000 is dissolved in an acidic aqueous solution (e.g. aqueous solution of acetic acid, dichloroacetic acid, etc.) to a concentration of 2W20wt%, and the solution is dripped into a basic solution composed of a basic substance (e.g. NaOH, ammonia, etc.) and water and/or an alcohol (e.g. methanol, ethanol, etc.). The obtained spherical coagulum is washed with water and dried to obtain the objective product. n COPYRIGHT: (C)1986,JPO&Japio |
