PURPOSE:To obtain the titled substance in high yield, by isomerizing 5-vinyl-2- norbornene in the presence of a catalyst containing an alkali metal supported on a carrier consisting of an alkaline earth metal oxide and alkali metal hydroxide or alkoxide. CONSTITUTION:5-Vinyl-2-norbornene is isomerized to the titled substance. The reaction is carried out in the presence of a catalyst containing an alkali metal, particularly Na supported on a carried consisting of an alkaline earth metal oxide, preferably CaO and hydroxide or alkoxide, preferably ethoxide of an alkalie metal at 15-100 deg.C for 10-40min. The hydroxide or alkoxide of the alkali metal which is a constituent component of the carrier is incorporated an amount of 5-15wt% based on the total weight of the catalyst and the amount of the supported alkali metal is 5-10wt% based on the weight of the carrier. USE:A diene component of ethylene-propylene-diene polymers. |
