Cyclopentadiene → Cyclopentene

Participants

Reaction Steps

reacting the purified cyclopentadiene of step (B) with hydrogen gas in the ratio of 1 to 1.5 mol hydrogen to 1 mol cyclopentadiene, in the presence of a palladium catalyst on a carrier and at a temperature of 50° to 200° C and at substantially ordinary atmospheric pressure thereby to produce a conversion ratio of 90 to 98% cyclopentene, remainder unreacted cyclopentadiene;
