Fragmentation of Chitosan by Acids

Figure 3

The normalized intrinsic viscosity of chitosan fragments, , as a function of reaction time (0–300 min) for fragmentation of chitosan solution (1.0% w/v) by 0.5 N HCl at 65°C. Open circle for experimental point and dotted line for curve fit. The reaction was performed at 65°C, and intrinsic viscosity was measured at 25°C.
