Abstract: A process is provided for producing glutaric acid through oxidation of cyclopentene using a ruthenium compound oxidizing agent. The solvent for the reaction system is usually a halogenated hydrocarbon or a mixture of a halogenated hydrocarbon and an aliphatic nitrile. The oxidizing agent is added continuously or intermittently together with a co-oxidizing agent, such as sodium hypochlorite, in an aqueous alkaline solution. The process makes it possible to produce glutaric acid efficiently from cyclopentene.

Abstract: A process for the production of conjugated diolefins having 4-6 carbon atoms from the corresponding monoolefins according to the oxidative dehydrogenation process wherein oxides of molybdenum, arsenic and an alkaline earth metal are used as catalyst. The use of this catalyst enables the production of conjugated diolefins in a high yield.
