It is known that acidic ionexchange resins are successfully applied for adsorptive removal of Cr 3+. 22,23 Encouraged by that, we envisioned the preparation of Cr 3+ modified ion exchange resins as promoters for the glucose dehydration. A series of such catalysts was obtained by adsorption of Cr 3+ over ionexchange resins in MeOH solutions ...
