Abstract

PURPOSE: To obtain an isobutene tetramer useful as a solvent, etc. in high selectivity in high yield, by dimerizing isobutene dimers using sulfonic acid or its derivative, or perchloric acid or its derivative as a catalyst.
CONSTITUTION: When isobutenes shown by the formulaI, II, etc. are dimerized to give an isobutene tetramer, a compound (e.g., fluorosulfuric acid, trifluoromethanesulfonic acid) shown by the formula III (R is halogen atom, halogen substituted hydrocarbon), perchloric acid, or its derivative (e.g., benzoyl perchlorate), is used as a catalyst. The amount of the catalyst is preferably 0.1W100 milmole based on 1mol isobutene dimer. The reaction is carried out in a solvent such as n-hexane, etc. at -30W100°C.
