Abstract
An improved process for the preparation of isobutene dimer comprising passing isobutene and a controlled amount of t-butanol and/or water (water reacts with isobutene under the conditions of the reaction to form t-butanol) through a fixed bed acidic cation exchange resin, producing only a hydrocarbon phase, removing the hydrocarbon phase, splitting the hydrocarbon phase, and recycling a portion thereof to the reaction. The recycle provides the means to control the temperature of the reaction by cooling the recycle and providing a heat sink. The controlled amount of t-butanol and/or water suppresses or inhibits the production of isobutene high polymers, e.g., trimers, tetramers and codimers (butene is also a common component of available C.sub.4 feed streams).
