One-pot citral transformation to menthol over bifunctional micro- and mesoporous metal modified catalysts: Effect of catalyst support and metal
Citral transformation to menthols was conducted in liquid phase over Ni supported H-MCM-41 and H-Y. The highest selectivity to four different stereoisomers of menthol and to (+/-)-menthols over Ni-H-MCM-41 were 54 and 38%. respectively. The effect of different metals (Ni, Ir, Ru, Pd) was studied over H-MCM-41. The selectivity to menthols decreased in the following order: Ni > Pd > Ru > Ir. (c) 2005 Elsevier B.V. All rights reserved.
