    摘要: 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.

    摘要: A combined process for preparing alumina and alpha-olefins (.alpha.-olefins) is disclosed. The process comprises:(a) reacting tri-(C.sub.2 to C.sub.24) alkylaluminum with ethylene in the presence of nickel catalyst to form triethylaluminum and C.sub.2 to C.sub.24 .alpha.-olefins,(b) adding aluminum tri-(C.sub.4 to C.sub.8) alcoholate to the reaction product of step (a),(c) equilibrating the admixture of step (b) so that substantially all of the triethylaluminum is converted into aluminum ethyl alcoholates, compounds with at least one C.sub.4 to C.sub.8 alcoholate group per molecule,(d) subjecting the equilibrated mixture of step (c) to a fractionation to recover, (1) a C.sub.2 to C.sub.24 .alpha.-olefin fraction, and (2) an aluminum ethyl alcoholate fraction (a mixture of compounds with the general formula Al(C.sub.2 H.sub.6).sub.X (OC.sub.6 H.sub.13).sub.Y (where X is 0 to 2 and Y is 3 to 1) and X+Y=3).(e) adding C.sub.4 to C.sub.8 alcohol to the aluminum ethyl alcoholate fraction to form aluminum tri-(C.sub.4 to C.sub.8) alcoholate and ethane,(f) separating the ethane and aluminum tri-(C.sub.4 to C.sub.8) alcoholate by fractionation, and(g) hydrolyzing the aluminum tri-(C.sub.4 to C.sub.8) alcoholate to form C.sub.4 to C.sub.8 alcohols and the desired alumina,and process being characterized further in that preferably the tri-(C.sub.2 to C.sub.24) alkylaluminum is prepared by:(1) preparing triethylaluminum from aluminum, ethylene and hydrogen, in two stages, and(2) reacting with triethylaluminum of step (1) with ethylene to form tri-(C.sub.2 to C.sub.24) alkylaluminum.
