Process for preparing aqueous chitosan solutions and gels |
| abstract |
The invention relates to a process for the preparation of aqueous solutions and gels of chitosan, in which chitosan and an acidic chelating agent are dissolved in water.n n n Such solutions can be drastically increased in viscosity or converted into highly viscous gels by adding salts of polyvalent metals and acids in which chitosan is only moderately soluble or insoluble.n n n Salt-like chitosan-chelate complex adducts can be obtained from such solutions by dehydration or by precipitation with an organic solvent. |
