Highly selective hydrogenation of benzene to cyclohexene catalysed by a SiO2- or Al2O3-imnnobilized lanthanide catalyst
Abstract
Ytterbium catalysts immobilized on SiO2 or AI2O3, which are formed by the reaction of the support with the lanthanide dissolved in liquid ammonia, area new catalytic material for the partial hydrogenation of benzene to cyclohexene with extremely high selectivity of 96–100%.
