| dc.description |
Catalytic conversion of sucrose by means of nickel-tin alloy catalyst supported on
aluminium hydroxide (Ni-Sn/AlOH) in aqueous solution under hydrogen gas atmosphere at
383-453 K produced levulinic acid, -valerolactone and hexitols (sorbitol and mannitol).
Ni-Sn/AlOH catalysts were easily obtained by a simple synthetic procedure according to
our previous report [1]. Raney nickel supported on aluminium hydroxide (R-Ni/AlOH) was
obtained from the alkali leaching of Raney Ni-Al alloy using a dilute sodium hydroxide
solution [2]. The mixture of R-Ni/AlOH and a solution containing tin species was treated
hydrothermally in the sealed-teflon autoclave reactor at 423 K for 2 h. R-Ni/AlOH catalyst
gave only hydrogenated products such as mannitol and sorbitol at 433 K, 2.0 MPa of H2 for
12-24 h. In contrast, Ni-Sn/AlOH catalyst gave levulinic acid product then continuously
converted into -valerolactone as main product instead of the hexitols at the same reaction
conditions. The addition of tin and the formation of Ni-Sn alloy are believed to play
important role on the product distribution.
