Abstract  

This work describes the experimental determination of sucrose hydrolysis kinetics using a heterogeneous catalyst. We used an Amberlite IR-120 strong acidic cation-exchange resin. The experiments were performed under previously determined optimal process conditions: sucrose mass concentration, γS = 50 g L−1, catalyst mass concentration, γC = 180 g L−1, rotational frequency of the stirrer fm = 180 min−1, and temperature ϑ = 79 °C. The parameters of the supposed kinetic model were determined using experimental data. The kinetics of sucrose hydrolysis over Amberlite IR-120 has not been reported to date. Therefore, we could not directly compare the calculated values of kinetic parameters with those from the literature. However, the calculated values are within the range of values determined by other types of catalysts. Furthermore, we investigated the influence of catalyst mass concentration γC on the reaction rate constant k′.
