Abstract: A process is described for coproducing vinylidene alcohol and vinylidene olefin. The process involves dimerizing one or more vinylolefins with an alkyl aluminum catalyst to form a first product mixture comprising at least vinylidene olefin and alkyl aluminum compound. The vinylidene olefin is then reacted with the alkyl aluminum compound under displacement conditions to form 1-olefin while concurrently removing the 1-olefin from the displacement reaction mixture to form a second product mixture comprising at least beta-branched alkyl aluminum compound. The second product mixture is treated with air or oxygen under mild oxidation conditions to form a third product mixture comprising at least beta-branched aluminum alkoxide. The beta-branched aluminum alkoxide is then hydrolyzed to form vinylidene alcohol. The process makes effective use of the alkyl aluminum catalyst both as a catalyst and as a reactant, and requires only a relatively small amount of reaction equipment.

Reactive distillation effects a shift of the chemical equilibrium away from the trialkylaluminum compound and toward the production of tri-(beta-branched alkyl)aluminum. compound.

Abstract: Olefin is formed by displacing alkyl groups of aluminum trialkyl by contacting ethylene with the aluminum trialkyl in an ethylene:aluminum trialkyl mol ratio in the range of 2-8:1 at about 0.degree.-70.degree. C. and at atmospheric up to about 1000 psia pressure, for a reaction time of about 0.5 to about 60 minutes in the presence of a displacement enhancing amount of a nickel- or cobalt-containing displacement catalyst. Despite the fact that the displacement reaction is an equilibrium reaction, the process does not use, as did the prior art, large excesses of ethylene to shift the equilibrium to favor displacement. Consequently, the volumes of ethylene used in the processing are reduced very substantially and yet yields of the desired displaced alpha olefin remain favorable.
