ENTENE

摘要

4-methyl-1-pentene is produced via the catalyst dimerization of propylene. Using a catalyst comprising at least one element selected from uranium and the rare earth metals. The selectivity to 4-methyl-1-pentene usually is at least 94 mole percent. The preferred catalysts are uranium and rare earth di(poly-substituted cyclopentadienyl) hydride complexes especially uranium (pentahaptopenta methyl cyclopentadienyl) hydride complexes.
