Patent

CA 2152669

The invention relates to the oligomerization of olefins or olefin mixtures, in particular long-chain hydrocarbon mixtures containing 6-20 carbon atoms or butenes, or mixtures of these said olefins, by means of a BF3/cocatalyst complex, the cocatalyst being water, a C2-C10 monoalcohol or a C2 C10 monocarboxylic acid. Examples of especially preferred cocatalysts are pentanol and n-valeric acid. BF3 is fed in gaseous state into the oligomerization reactor, and the reactor is pressurized thereby. In case a monomer mixture is oligomerized, the product is a true co-oligomer and it also contains double bonds which increase product ractivity, needed when the oligomer is used as an intermediate.
