    摘要: A process for the hydrogenation of certain aromatic, olefinic and acetylenic compounds. The process is catalyzed by a zero-valent mixed metal catalyst which is in turn prepared by the reaction of an organic metal cluster compound wherein one of the metals is lithium with a complex of rhodium halide and an olefinic hydrocarbon ligand. The catalyst may, if desired, be deposited on a support such as alumina or silica. The hydrogenation process can, in many instances, be carried out under ordinary conditions, i.e., at room temperature and atmospheric pressure.

    摘要: Producton of cyclopentene by splitting of dicyclopentadiene to produce cyclopentadiene and hydrogenating the cyclopentadiene to produce the cyclopentene in crude form, and distilling the crude cyclopentene to separate low boilers and high boilers therefrom and provide the cyclopentene product. The high boilers are recycled to the dicyclopentadiene splitting stage and serve to reduce resin formation in that stage. The process is particularly effective where the dicyclopentadiene has a low content of the so-called "codimers" which, if present in sufficient amount, would reduce resin formation.
