METHOD OF PREPARING CONJUGATED DIOLEFIN WHICH COMPRISES CONTACTING A NON-CONJUGATED VINYLCYCLOHEXENE AT A TEMPERATURE IN THE RANGE OF -40*C. TO +40*C. AND FOR A TIME SUFFICIENT TO EFFECT SUBSTANTIAL CONVERSION WITH A SODIUM-ON-ALUMINA CATALYST IN WHICH THE PROPORTION OF SODIUM THEREIN IS 0.1-3.0% BY WEIGHT, AND RECOVERING FROM THE REACTION MIXTURE CONJUGATED DIOLEFIN HAVING A TWO-CARBON ATOM CHAIN ATTACHED TO A CYCLOHEXENE RING.
