preparation example Construction
[0060] The preparation method of described water-soluble chitosan is as follows:
[0061] Add 15g of chitin and 450ml of 40%-50% NaOH solution into a 1000ml three-neck flask, and stir the reaction with an electric stirrer for 5-15min in a water bath at 60-100°C. After the reaction was completed, the sample was lowered to room temperature, and the sample was poured into a 120um stainless steel sieve, and most of the NaOH was recovered by pressure filtration, washed with a large amount of water until neutral, and dried in an oven at 80°C to obtain the water-soluble chitosan.
[0062] In the present invention, chitosan with different degrees of deacetylation is prepared by adjusting the concentration of NaOH solution and the reaction temperature. They are chitosan with deacetylation degrees of 58, 62, and 64, respectively. With the increase of NaOH concentration, the reaction speed and degree of chitin deacetylation increased, but the viscosity decreased. As the reaction temper...
