수지 촉매에 의한 Polyfructan의 가수분해

Hydrolysis of Polyfructan by Resin Catalysts

Hydrolysis of inulin was investigated employing various commercially available resin catalysts for the production of high grade fructose syrup. The particle size and porosity of the resin significantly affected the distribution of the products, indicating that the intraparticle diffusion of reactants controls thc selectivity as well as the reaction rate. To confirm the effect of the intraparticle diffusion, two different types of resin catalysts were prepared: the one having sulfonic acid group distributed uniformly throughout genular microparticles (A-type) and the other having sulfonic acid group located mainly at the exterior surface of genular microparticles (E-type). The results were found that the reaction rate and the selectivity of the E-type catalyst were higher than those of the A-type catalyst.
