Kinetic pH Titration to Predict the Acid and Hydrothermal Conditions for the Hydrolysis of Disaccharides: Use of a Microcapillary System

Figure 3

Kinetic pH titration. (a) Time course of remaining sucrose concentration under various pH conditions at 180°C. The experiment was performed at 180°C, 10 MPa, C₀ = 0.5 wt%, and initial pH 4–10. (b) Relationship between the induced time (t_d) and apparent rate constant (k^app). (c) Time course of the pH at the outlet of reaction system. (d) Relationship between t_d and the corresponding pH (pH^amb).
