Abstract: Cyclic ketones of the formula I where n is an integer from 4 to 6, are prepared by converting an aliphatic dicarboxylate of the formula R1OCC-(CH2)n-COOR2II where n has the above meaning, R1 and R2 are each alkyl, cycloalkyl, aralkyl or aryl and R2 may furthermore be hydrogen, at from 150 DEG to 450 DEG C. over a solid oxide catalyst.

Abstract: Pure monoesters of adipic acid are prepared by a process in which (a) a pentenoate is reacted with carbon monoxide and hydrogen at from 90 DEG to 140 DEG C. and under from 5 to 300 bar in the presence of a carbonyl complex of cobalt or of rhodium, and a 5-formylvalerate is separated off, and (b) the 5-formylvalerate thus obtained is oxidized with molecular oxygen, or with a gas containing this, at from 20 DEG to 100 DEG C. under from 1 to 10 bar.

Abstract: The invention concerns the manufacture of a hydrogenation catalyst by the reduction of platinum from an oxidation state of not less than two with a reducing agent in an aqueous medium in the presence of a carbon-containing support following partial poisoning, the method using a compound of general formula (I) in which X, Y and Z, which may be the same or different, are hydrogen, C1-C18 alkyl, C5-C10 cycloalkyl, halogen, hydroxyl, C1-C6 alkoxy or-NR'R'', whereby R, R' and R'', which may by the same or different, are hydrogen, C1-C18 alkyl or C5-C10 cycloalkyl. The invention also concerns a hydrogenation catalyst manufactured by this method, its use in the production of hydroxylammonium salts, a method of producing hydroxylammonium salts and a method of regenerating platinum-based hydrogenation catalysts of this kind.
