Hydrogenation of the carbonyl groups in furfural compounds may produce furfuryl alcohol. Furfuryl alcohol is used in poly(furfurylalcohol) resin and pharmaceutical industries. The hydrogenation process of furfural generally uses high pressure H2. Research related to hydrogenation at a pressure of 1 atm using hydrogen sources other than H2 recently grew as an alternative to a more desirable process. The conversion of furfural to furfuryl alcohol by transfer of the hydrogen alcohol to the carbonyl group is known to be facilitated by Lewis MOF zirconium(IV) acid. Three zirconium MOFs, namely UiO-66, DUT-52 and MOF-808 were used as catalysts and their catalytic performances were observed. As a source of hydrogen, 2-propanol was observed to give better furfural conversion than methanol and ethanol. The reaction yield and furfural conversion were observed by gas chromatography and 1H-NMR (60 MHz). Researcher from UST Korea observed a non-catalytic behavior of DUT-52 when it was employed in the furfural reaction under 2-propanol. As DUT-52 was reportedto have stronger Lewis acidity than UiO-66, the nature of DUT-52 was predicted to have a good catalytic performance in such a reaction. Herein, DUT-52 showed a catalytic activity ofthat was equivalent to that of UiO-66 at 140 °C and 5 h reaction (TOF = 3?5 h?1). This phenomenon was in accordance with the initial hypothesis. The reaction was observed to follow a pseudo 1st reaction order with the highest turn over frequency (TOF) of 6?7 h?1. DUT- 52 was also observed to have a good regeneration potential with a catalyst mass regenerationof 80% and a post-regeneration furfural conversion of 92%.
