Furfuraldehyde (FALD) is one of the promising chemicals from biomass lignocellulosic. FALD has a various derivatives that have many uses in vehicle fuel and raw materials of the chemical industry. The hydrogenation of FALD in the aldehyde group can produce furfuryl alcohol (FOL). FOL is an important material to make other FALD derivatives with value added. Hydrogenation of FALD to FOL generally uses pressurized hydrogen gas (20- 100 bar) and is catalyzed by platinum group metals. The catalysis reaction using pressurized hydrogen gas is dangerous and requires complicated of infrastructure and processes. The platinum group metals are quite expensive due to their low abundance. This research studied the catalytic performance of Ni(II)-phenoxyimine complex in the transfer hydrogen reaction of FALD to FOL with the alcohol as a hydrogen source. The ligand is synthesized by a reaction of 2-hydroxybenzaldehyde and aniline derivatives. The phenoxyimine ligand has been reacted with nickel chloride salt to produce a Ni(II)- phenoxyimine complexes. The ligand and complex has been characterized by FTIR, PXRD, H-NMR, and MS. The product of the hydrogenation reaction is observed by gas chromatography (GC). The selectivity of hydrogen transfer reaction FAL to FAL in this research achieved >99% with a FOL yield of 87% and a TOF value is 2,9 h?1 . The optimum condition reaction used was 160 °C for 6 h with a catalyst concentration is 5 mol% and isopropyl alcohol as the hydrogen source. The result indicates that Ni(II)-phenoxyimine has the potential as a catalyst of transfer hydrogen reaction FALD to FOL.
