Abstract
Fructose dehydration is one of the ways to produce HMF, a biobased building block. In this work a kinetic model is developed for this reaction. To prevent side reactions to humins, methanol was used as a solvent. In total 85 experiments with varying temperature (100°C or 120°C), initial concentration (0.1, 0.2 or 0.4 M) and acid concentration (8, 16 or 32 mM) were done with starting compound Fructose, HMF, MMF and LA. As a basis, the model from van Putten was used, which involves only first order reactions. Several models were tested, and finally a model as shown in Figure 1 was selected as the best model. All reactions were shown to be first order in reactant and acid, and reaction 2, -3, -4, 5 and -9 are also first order in water. Finally became clear that reaction two is not occurring, and was removed from the model which did not change the goodness of fit.
