reported a reaction order of 1 on substrate for the dehydration of fructose. In accordance with this result, a kinetic analysis of the dehydration of fructose in DMSO over Zr-P-Cr catalyst was performed according to previouly described methods. As summarized in , the value of k increases with increasing temperature, indicatingnthat higher temperature accelerated fructose dehydration reaction rate. Plots of lnk vs reaction time (t) were used to obtain first-order kinetic constants. An Arrhenius plot was obtained, as shown in (..). An apparent activation energy of 101.3 kj/mol was obtained for fructose dehydration.
