Trimerization of isobutene over Amberlyst-15 catalyst

The purpose of this investigation is to study the oligomerization of isobutene over Amberlyst-15 catalyst in a mixed gas-liquid phase. Reaction conditions were optimised in order to maximise triisobutylene selectivity. Results show that more than 90% (w/w) triisobutylene was present in the final oligomer mixture.
