Sucrose inversion was carried out in a batch reactor, using two types of macroreticular resin catalyst (Amberlyst 15 and Amberlyst XN-1010). Experimental data were obtained to determine the effect of particle size, reaction temperature and resin amount on the initial reaction rates. A two-phase model, proposed by the authors, was applied to elucidate the interaction between reaction and diffusion inside the resin particle. The present reaction is of first order and the overall effectiveness factor can be expressed analytically in terms of the pore- and the microparticle effectiveness factors together with the fraction of active acidic sites exposed to the pore space. The experimental data were in excellent correlation with the proposed model.
