H(3)PMo(12)O(40) Immobilized on Amine Functionalized SBA-15 as a Catalyst for Aldose Epimerization

In this work various amount of phosphomolybdic acid (PMo) were immobilized on amine functionalized SBA-15 and used as heterogeneous catalysts in the epimerization of glucose in aqueous solution. 13.3PMo/NH(2)-SBA-15 exhibited the best catalytic performance with a glucose conversion of 34.8% and mann...

description In this work various amount of phosphomolybdic acid (PMo) were immobilized on amine functionalized SBA-15 and used as heterogeneous catalysts in the epimerization of glucose in aqueous solution. 13.3PMo/NH(2)-SBA-15 exhibited the best catalytic performance with a glucose conversion of 34.8% and mannose selectivity of 85.6% within two hours at 120 °C. The activation energy of 80.1 ± 0.1 kJ·mol(−1) was lower than that of 96 kJ·mol(−1) over the homogeneous H(3)PMo(12)O(40) catalyst. The catalytic activities of 13.3PMo/NH(2)-SBA-15 for the transformation of some other aldoses including mannose, arabinose and xylose were also investigated.
