ABSTRACT:
A process for producing 2,6-dimethyl-1,3,6-octatriene by dimerizing isoprene in the presence of a novel catalyst composition, which comprises: (A) a zirconium component represented by the formula: Zr(OR).sub.n Cl.sub.4.sub.-n wherein R is a chlorinated alkyl group containing two to 20 carbon atoms or a chlorinated cycloalkyl group containing three to 20 carbon atoms, and n is an integer of 1 to 4; (B) an aluminum component represented by the formula: AlR'.sub.m Cl.sub.3.sub.-m wherein R' is an alkyl group containing one to 10 carbon atoms, a cycloalkyl group containing three to 10 carbon atoms, or an aryl group, and m is 1.5 or 2; and (C) a coordinating component.
