ABSTRACT:
A process of the production of isoprene cyclic trimers, i.e., 1, 5, 9- and 1, 6, 9-trimethylcyclododecatriene-(1, 5, 9) through a catalytic oligomerization of isoprene by employing a catalyst prepared by a combination of a tri-valent titanium compound, an organoaluminum compound, an oxygen-containing compound such as carbonyl and ether compounds, and a compound such as a sulfur-containing compound and a nitrile compound.
