摘要: Abstract The study of isoprene (2-methyl-1,3-butadiene) gas phase hydrogenation on ThNi 2 and UNi was undertaken the effect 5f element nickel catalytic behavior investigated. At nearly steady state, reaction products were isopentane isopentenes (2-methyl-2-butene, 2-methyl-1-butene 3-methyl-1-butene). total selectivity to higher (∼80 mol%) than (∼50 mol%) but, in both cases lower that pure Ni (∼96 mol%). sum 2-methyl-2-butene + 2-methyl-1-butene selectivities (valuable for tert -amyl methyl ether process) ∼75 mol% , whereas it significantly (∼50 mol%). is time invariant. difference properties between can be explained by electronic transfer from generates an density supply nickel, which .
