Ketalization of acetone with 1,4- and 1,2-diols was carried out in the presence of cation exchange resin catalysts to obtain corresponding cyclic ketals viz. dioxepins, dioxepanes and dioxolanes. The reaction is equilibrium controlled and low conversions were achieved in batch mode. Mol. sieves in semi-batch reactive distillation mode were used to remove the H2O from the reaction mixture This resulted in high conversion of the limiting diol. The batch kinetics was explained by a pseudohomogeneous model. The effects of different configurations as well as various parameters were studied in detail to arrive at optimum conditions. An engineering solution was arrived at to make the process industrially feasible.
