The kinetics of continuous sucrose inversion catalyzed by fixed beds of acid form ion exchange resin was studied. A reactor 1 inch in diameter was used and solution flow rate and catalyst particle size were varied to cover a modified Reynolds number range of 0.014 to 4.8. Reaction temperature was varied from 50° to 75° C. The reaction was clearly first-order over this range and showed an activation energy of 15,950 cal. per gram mole. The data indicate that the observed rate of reaction is strongly influenced by diffusion within the resin particles and that external (film) mass transfer is not significant for the range of conditions explored.
