Claim 14:
15. A method for deactivating a residual transition metal-based catalyst system containing a co-catalyst comprising an aluminoxane and optionally an alkylaluminum in an effluent stream from an oligomerization reactor, the method comprising:
contacting the effluent stream, the effluent stream comprising unreacted ethylene, an oligomer product, the residual transition metal-based catalyst system containing the co-catalyst comprising the aluminoxane and optionally the alkylaluminum, and an organic reaction medium, with a C14-C18 alcohol co-catalyst deactivating agent at a molar amount of OH of the co-catalyst deactivating agent in a range from 0.5 to 1.5 times {(moles of aluminum of the aluminoxane)+(moles aluminum of the alkylaluminum)+(moles aluminum of the alkylaluminum)}.
