Abstract
A process is provided to inhibit trimerization catalyst system activity which comprises the sequential steps of contacting a reactor effluent stream with alcohol; removing any desired olefin products; adding an aqueous base to the non-olefin portion; removing a precipitate; separating the aqueous and organic phases; and adding an acid to the aqueous phase.
