Abstract:
Chromium-based metal-organic frameworks MIL-101 and MIL-100 catalyzed oxidation of propyleneglycol (PG) using tert-butyl hydroperoxide (TBHP) as oxidant. The main oxidation product was hydrox-yacetone (HA) while minor oxidation products were acetaldehyde and acetic acid. The best results (88%selectivity toward HA at ca. 10% PG conversion) were achieved over MIL-101 using acetonitrile as solvent.In water, C C bond cleavage products predominated. MIL-101 and MIL-100 revealed different behaviortoward adsorption of PG from MeCN solution, which affected their catalytic performances. Additives ofradical chain scavengers produced a strong rate-inhibiting effect whereas the presence of molecular oxy-gen accelerated the reaction, suggesting radical chain mechanism of the oxidation process. The oxidationof PG over MIL-101 at 50◦C proceeded without leaching of the active metal into solution and the catalysishad the truly heterogeneous nature. The MIL-101 catalyst could be recycled without significant loss ofactivity and selectivity and preserved its structure during, at least three, catalytic cycles.
