    摘要: Production of unsaturated ketones by the aldol condensation of ketones such as acetone or methyl ethyl ketone by contacting the ketone in the vapor phase with a particulate catalyst comprising at least one basic alkali metal compound supported on an inert substrate at a temperature above 175° C. The produce ketones may be hydrogenated to form saturated ketones or alcohols.

    摘要: C-8-substituted 1,5-dimethyl-bicyclo[3.2.1]octane-8-ols having the general formula I ##STR1## wherein R is a lower open chained or cyclic alkyl- alkenyl- or alkinyl group having up to 6 carbon atoms and the wavy line at the C-8 atom means epimeric forms, the process for producing these compounds and their use as odorants and constituents of parfume composition for cosmetic and industrial parfuming or essential oils and flavoring agents.
