ABSTRACT:
A process for producing cycloalkadienes in liquid phase by metathesis reaction of cycloalkenes in the presence of a carrier catalyst based on Re.sub.2 O.sub.7 /Al.sub.2 O.sub.3. The cycloalkenes in the form of 0.01 to 0.05 molar solutions are contacted with the carrier catalyst in a fixed bed arrangement with contact times of 10 to 100 seconds.
