Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

C07C 2914

US Classification:

568881

Abstract:

Process for the hydrogenation of carbonyl-containing compouds at mild conditions of temperature and pressure to produce alcohols or amines is disclosed, employing catalysts comprising palladium and zinc on an inorganic support. A method for the preparation of these supported catalysts which are useful for the desired reductive conversion is also disclosed.

Abstract:

A method for selective dehydrogenation of a compound, comprising contacting a compound of the formula ##STR1## wherein each R. sup. 1, R. sup. 2, R. sup. 3 and R. sup. 4 is independently selected from the group consisting of H, (C. sub. 1 -C. sub. 20) alkyl, (C. sub. 3 -C. sub. 20) cycloalkyl, (C. sub. 6 -C. sub. 20) aryl, (C. sub. 7 -C. sub. 20) alkylaryl, (C. sub. 7 -C. sub. 20) aralkyl groups, as well as substituted (C. sub. 1 -C. sub. 20) alkyl, (C. sub. 3 -C. sub. 20) cycloalkyl, (C. sub. 6 -C. sub. 20) aryl, (C. sub. 7 -C. sub. 20) aralkyl and (C. sub. 7 -C. sub. 20) arylalkyl moieties, optionally further substituted with --OR, wherein R is R. sup. 1, R. sup. 2, R. sup. 3 or R. sup. 4 ; and wherein R. sup. 1 and R. sup. 2 or R. sup. 3 and R. sup. 4 may be joined as part of a ring structure, at a dehydrogenation temperature in the presence of a catalyst comprising about 0.
