| Summary: | Fufural may be produced from biomass. It can be converted into other feedstock chemicals. Furfuryl alcohol (FOL) is one of derivatives obtained from hydrogenation of its carbonyl. Direct hydrogenolysis of furfuryl alcohol results in 1,2-pentanediol (1,2-PeD) which is commonly used as cosmetic preservatives, disinfectants, and feedstock in surfactants. Hydrogenolysis of furfural to 1,2-PeD and hydrogenation of furfural to tetrahydrofurfuryl alcohol (THFA) catalyzed by platinum group metals, such as Rh/OMS-2, has been reported commonly in the presence of pressurized hydrogen (5-45 bar). Platinum group metals are relatively low in natural abundance and the use of high-pressure hydrogen bears difficulties in handling and the chemical infastructure. Herein, vanadyl@MOF-808 was used as catalyst for hydrogenolysis of furfural in alcohols. Heterogeneous vanadyl and its constraint geometry in the MOF may enhance the activity in hydrogenolysis. 2- Propanol and ethanol were used as the hydrogen source because of their ease in handling, non-toxic, and environmentally benign. Here, vanadyl@MOF-808 (3.5 mol% V) converted >99% furfural into >99% 1,2-PeD (>99% selectivity) at 160
?C for 11 h in 2-propanol, with turnover frequency (TOF) of 2.62 h?1. |
