| titleOfInvention | Method for dissolving chitosan through combined use of acid and alkali |
| abstract | The invention discloses a method for dissolving chitosan through combined use of acid and alkali. The method comprises the steps of mixing lithium hydroxide, potassium hydroxide, urea and water according to mass percentage, so as to obtain an alkaline aqueous solution; adding a chitosan raw material into an acetic solution or hydrochloric solution, and carrying out stirring dispersion for 20-60 seconds, so as to obtain a chitosan-containing solution; uniformly stirring and mixing the alkaline aqueous solution and the chitosan-containing solution according to the volume ratio of 1: 1, freezing and unfreezing, thereby obtaining a chitosan solution. According to the method, acidic-alkaline solvent systems are used in a combined manner, so that an alkaline system solution of chitosan is obtained, and the degradation of chitosan in an acidic solution is avoided; moreover, the processes of swelling and solvent system pre-cooling are not required, so that the dissolving time is shortened, and the dissolving efficiency is increased. |
