Abstract:
This is a catalyst and a process for partially hydrogenating polycyclic and monocyclic aromatic hydrocarbons such as benzene, naphthalenes, biphenyls, and alkylbenzenes to produce the corresponding cycloolefins. The catalyst is a hydrogenation catalyst comprising ruthenium and a promoter metal, such as cobalt, on a composite support. It is a process in which the product cycloolefin is produced in high yield and with high selectivity.
Abstract:
This invention is a process for the production of trialkyl acetic acids, particularly of pivalic acid, from branched olefins, particularly isobutene, and carbon monoxide using a solid acid catalyst and optionally with minor amounts of a Lewis acid such as boron trifluoride.

Abstract:
L'invention se rapporte à un catalyseur et un procédé permettant d'hydrogéner partiellement des hydrocarbures aromatiques polycycliques et cycliques comme le benzène, le naphtalène et l'alkylbenzène, afin de produire les cyclo-oléfines correspondantes. Le catalyseur consiste en un catalyseur d'hydrogénation se composant de ruthénium sur un support composite. Ledit procédé permet de produire des cyclo-oléfines en grande quantité et avec une grande sélectivité.
