terms to the shunt reaction, k4 and k–4 with which the parameter number that must be adjusted is six, and the model is reduced to one of second order for the consecutive reactions. In the second scenario, which exactly belongs to the one that shows Eq. 3, the two equilibrium constants of the shunt reaction were included, and therefore eight parameters must be calculated.
Figure 5 shows experimental and calculated data from the kinetics model of second order for the three consecutive reactions at 50 C, 0.2 wt% of NaOH and molar ratio 6:1. The rate constants for the two proposed scenarios are presented
